How to Care for and Fix Hot Toys and Sixth-Scale Figures

Every repair starts with knowing the material in front of you, because the right care for one is the wrong care for its neighbour. A premium sixth-scale figure is usually some mix of these:

Fabric: the tailored costume, often with fine stitching, wires in collars and capes, and dark dyes. Coated fabric, sold as pleather or faux leather: a thin polyurethane film on a fabric backing, used for jackets, belts, boots, gloves and holsters. Soft rubber and flexible PVC (vinyl): rubber suits, muscle bodies, capes, vests and most head sculpts. Seamless bodies: a soft skin, often silicone or a thermoplastic elastomer (TPE), over a metal or plastic skeleton. Hard plastic: armour, accessories and the clear plastic joints inside many bodies. Vacuum-metallised “chrome”: a microscopically thin aluminium layer on plastic. Die-cast metal: zinc-alloy armour on the die-cast editions. Magnets, LEDs and batteries.

Polyurethane, flexible PVC and rubber are the materials museum conservators watch most closely: as they age they can go sticky, discoloured, brittle or crumbling, and their breakdown products can harm whatever they touch. That is why so much of this guide is about keeping those materials cool, dark, unstressed and apart from their neighbours.

Each fix below carries three labels. EVIDENCE says what it rests on: OFFICIAL means a maker’s or battery maker’s own published instruction; SCIENCE means museum conservation research on these materials; COLLECTOR PRACTICE means what collectors report doing. Collector practice is anecdotal: it can suggest a technique that has worked for some people, but it is not a maker’s instruction and it is not a proven-safe treatment for every figure. RISK says how much damage the fix can do if it goes wrong. STOP IF says when to put the tools down.

The golden rules, before any of it: the gentlest method first; test on a hidden spot; change one thing at a time; and prefer the fix you can undo to the one you cannot.

Unbox slowly. Photograph the tray before you lift anything out, so the figure and its accessories can go back exactly as they came, and check every compartment: spare hands, stand parts and small accessories hide under trays and behind inserts. Do not force a lid shut over a part that sticks up.

Then check the figure the same day, even if it is going straight back in the box. A sealed box hides problems, and collectors report finding them months later when the return window has closed: joints stuck solid, a cracked shoulder socket on a brand-new figure, two identical hands where there should be a pair, a missing piece of costume. Move each joint gently, count the hands against the box contents in the Archive, and look closely at the paint.

If something is wrong on arrival, report it to the shop or the maker rather than repairing it yourself. A repair can make a claim harder, and makers and large retailers do replace parts: Sideshow, for one, states a return period on its product pages, and collectors report receiving missing parts from customer service. Photograph the fault, keep the packaging and write to the seller first.

Light fades fabric and paint, yellows white plastics and helps break down rubber and polyurethane, and the damage adds up: it is the brightness multiplied by the hours. Conservation guidance for light-sensitive collections keeps light low (a few tens to a hundred or so lux, far dimmer than a sunny room) and keeps ultraviolet to a minimum. Collectors see it on their own shelves: the red on some painted plastic armour slowly turning pink. A UV filter alone is not enough, because visible light does much of the fading too. Keep figures out of direct sun and away from windows, use LED lighting, which gives off very little UV, and light the case when you are looking at it rather than all day.

Heat speeds up almost every kind of ageing. As a rule of thumb from conservation science, chemical decay in unstable materials roughly doubles with every 5 °C, and halves with every 5 °C cooler. A conservation model for the most heat-sensitive materials (rubber and polyurethane among them) puts that in years: a few decades at around 20 °C, a handful of years at 30 °C, mere months in hot sun. Those numbers are an illustration of how strongly heat accelerates ageing in a generic, highly unstable material. They are not a predicted lifespan for any particular figure, suit or brand.

What it means on the shelf: keep cases away from radiators, heaters, sunny windows and hot attics; leave a gap of about 10 cm between a case and an outside wall; avoid halogen or incandescent bulbs inside closed cases, which heat what they light; and never leave a figure in a car, where summer temperatures run far above the air outside. Soft, dark surfaces in direct sun can reach temperatures that deform plastics and soften glues.

Humidity is where collectors get the most contradictory advice, and the honest answer is that a figure has competing needs. Fabric and organic materials grow mould when the air stays damp. Metals and magnets corrode faster in high humidity. Polyurethane breaks down faster with moisture and heat together. Very dry air, meanwhile, can make some plastics more brittle, and large swings back and forth stress everything. So there is no single magic number. Aim for moderate and steady, avoid long spells of damp, avoid heat, and measure before you change anything.

On mould, the museum figures are worth knowing with their conditions attached. Conservation guidance for susceptible organic materials such as leather and textiles, kept warm (around 25 °C), illustrates how quickly risk rises with humidity: roughly months at 70 %, days at 80 %, and a couple of days near saturation, with growth stopping when the air dries below about 55 %. Real risk depends on the material, on dust and dirt (which feed mould), on temperature, on air movement and on how long the damp lasts, so treat those numbers as a warning about sustained damp, not a countdown for your shelf.

A glass case keeps dust and fingers off and slows changes in the air, but what the case is made of matters. Fresh paint, MDF and chipboard, oak and some woods, and acid-cure silicone sealants (the kind that smell of vinegar) release acids inside a closed case that can tarnish metal. If you build or paint a cabinet, let the paint cure for at least three to four weeks before the figures move in. Glass resists moisture better than acrylic.

Keep electronic air ionisers and “air purifiers” that make ozone away from the collection: ozone attacks rubber, especially rubber that is stretched or bent, and it cracks across the stress.

Silica gel is not a sprinkle-and-forget fix. In conservation it is used to hold a sealed or nearly sealed case at a chosen humidity: the gel is conditioned towards that target, there is enough of it for the case, and the reading is checked over time. A few sachets thrown into a leaky cabinet do very little, and fresh dry gel in a sealed box can pull the air drier than some materials like. Measure first; use gel only if the reading says you need it and the case can hold it; and keep checking.

Hands carry oils, salts and moisture that can mark metal and soft finishes over time. Clean, dry hands are fine for most handling of stable surfaces. Nitrile gloves are worth it for bare metal and die-cast, for anything already sticky or tacky, and for parts that are hard to grip. Cotton gloves reduce your grip on a heavy figure and their lint catches on tacky or flaking surfaces, so they are a poor choice for figures.

Respect the joints. New figures are often stiff, and they loosen with gentle use; force is how sockets crack and pegs snap. Move a joint in its natural direction, support the limb close to the joint you are bending, and stop at the first sign of resistance or a creak. Collectors report upper arms splitting inside the costume and clear shoulder sockets cracking during posing.

The most important rule in this guide is about time. Soft rubber, vinyl and seamless skin that are held stretched or folded for a long time can set into that shape, and conservation research on rubber is clear that cracks form across the line of stress, along the fold. On figures, collectors report exactly that at the elbows, knees, armpits and crotch: rubber suits and muscle bodies cracking where they were bent, seamless bodies splitting at the elbow after months in one dramatic pose, suits creasing permanently where they were folded. Silicone and rubber suits that crease when posed can keep the crease.

A stand that grips the waist or crotch holds a figure up by pressing on it, and pressure over months is how suits get dented and marked. Collectors report finding marks months after setting up a dramatic pose on a posing-arm stand; the reports are anecdotal, but the mechanism (steady pressure on a soft material) is the same one behind rubber setting into a fold. Heavy die-cast figures are the usual exception collectors mention, because their hard armour takes the grip.

Falls do more damage than ageing. Sixth-scale figures are top-heavy and their ankles are small. Collectors report figures walking off a top shelf when a cabinet door was opened, and the hands broke on landing.

Fabric costumes are the easiest to keep: out of the light so the dyes do not fade, out of damp so mould has nothing to work with, and loosely stored with padded folds. The danger fabric poses is to others: dark dyes can migrate into pale vinyl and seamless skin (see the section on stains).

Pleather is the material collectors complain about most, and the one with the least good news. Most pleather on figures is a polyurethane coating on a fabric backing. As it ages, moisture and heat break the coating down by a process called hydrolysis; conservation research shows that the acids this releases speed up the breakdown further, and that the coating can crack, delaminate and flake away from the fabric. Collectors report it at every age: jackets, belts and boots flaking within days of arriving in hot weather, and figures still sealed in their boxes in climate-controlled rooms peeling within a year. Some of that is the batch and its unknown history before it reached you; none of it is your fault.

What keeps pleather longest is the same as everything else: cool, dark, steady air, no long spells of damp, and no tight folds. What does not keep it is a conditioner. Nothing reverses hydrolysis, and pleather that has started to flake cannot be brought back to new. Products sold for leather, car interiors or vinyl are not made for polyurethane-coated fabric on a painted figure, and some can stain or discolour. If you love the outfit, the realistic options are disguise, careful repair, or replacement, which are covered in the section on cracks, tears and flaking.

Soft rubber and flexible PVC (vinyl) rely on plasticisers to stay soft. Over years those plasticisers migrate out: first as a sticky or oily film on the surface, later leaving the material hard, brittle and cracked. Where soft vinyl presses against hard plastic or other materials, collectors report it sticking, softening or deforming at the contact point: vests fused to bodies, suits softened in the armpits, sticky tyres on vehicles. Once the plasticiser has gone it cannot be put back, so the work is all in prevention: cool, dark, unstressed, and not pressed against other materials.

Seamless bodies, with a soft skin over a metal or plastic skeleton, are wonderful to pose and demanding to keep. Collectors report skin splitting at the elbows, knees, armpits and feet (sometimes on bodies stored straight), the skeleton working through the skin at the feet, and skins going oily or tacky. Many of these skins are thermoplastic elastomers whose softening oils are not chemically bound, so the oil slowly rises to the surface; heat speeds that up, and it is also why glue repairs on seamless skin rarely last. Most owners report no problems, some report “bad batches”, and the care is the same: neutral poses for storage, undressed or in pale, colourfast clothes, cool, dark and dry.

A premium head sculpt is painted in many fine, matte layers with glossy eyes, and it is the part most easily ruined by enthusiasm. Rubbing a matte skin tone polishes it shiny; most cleaning products dissolve or lift paint; and anything abrasive removes it. Dust it with a soft dry brush and leave it at that unless something has actually landed on it.

Rooted and sculpted hair attract dust; a soft brush or a gentle puff of air is enough. Keep the head out of the light, which fades fine skin tones before anything else.

Vacuum-metallised “chrome” is a layer of aluminium only a fraction of a micron thick on top of plastic, and once it is worn through it is gone. Handle chrome parts by their edges, and dust them with a soft dry brush or a barely damp cloth only.

Die-cast armour is tougher than painted plastic and much heavier. Collectors report die-cast suits wearing well over years where the plastic versions’ red has turned pink, but the evidence on die-cast is thinner than on any other material in this guide: reviews and owners’ reports, not studies. What is well established is general: metals corrode faster in damp air, so die-cast belongs in the same moderate, steady humidity as everything else, handled with clean hands or nitrile gloves to keep skin salts off bare metal. Owners mention removable panels loosening with use and armour edges catching each other; move panels gently and in their intended direction.

The weight is the other thing to respect. A heavy figure puts more load on small ankles and on any stand that holds it, so give die-cast figures a stable base, and support the body, not a limb, when you lift them.

You may read about “zinc pest”, the crumbling of zinc castings. It mainly affects old castings made with impure zinc, generally before about 1960, and it is not a reason to worry about a modern die-cast figure.

Small neodymium magnets are built into many figures to hold armour, weapons and accessories. These magnets rust if their plating is breached, and a rusting magnet loses some of its strength. Keep them dry, and do not prise at a magnet with a metal tool.

Wired capes hold a shape because of a thin wire sewn into the edge, and wire snaps when it is bent back and forth at the same spot. Bend a cape’s wire in gentle curves, change the bend points over time, and avoid folding it sharply for storage. One maker’s own display advice for capes is to clip external display wires to the cape’s ends rather than relying on the sewn-in wire alone.

Hands that will not come off are the most common frustration in the hobby, and snapped wrist pegs are the most common injury that follows. The rule for every stuck part: pull straight, never twist, and stop before anything bends that should not.

Some collectors use gentle warmth to soften a stuck soft-plastic part. That technique is collector practice, not a maker’s instruction, and it is bounded below with care. Heat guns are not gentle warmth: they run at hundreds of degrees, and plastics, paint, glues and seamless skin can deform or fail at a fraction of that. Boiling water is not gentle warmth either.

A body that cannot hold a pose is usually a loose joint rather than a broken one. Start with what can be undone.

The most common stain on a figure is not dirt but dye: colour migrating out of dark fabric, black pleather linings, dark thread or tight elastic and into pale vinyl or seamless skin. Collectors report it on necks under dark collars, on hands under coat cuffs and across seamless bodies under dark outfits. Heat, moisture and pressure all speed it up, which is another reason to keep figures cool, dry and not squeezed.

Sticky, tacky or oily surfaces are usually plasticiser or oil rising out of soft vinyl, rubber or seamless skin. Conservation research on PVC objects suggests that gently removing that surface film carries little risk of speeding the process up, and the film attracts dust if left. It will come back over time, because the material is still giving off what made it sticky; keep sticky parts from touching other figures and materials.

Fingerprints and smears on armour, visors and glossy parts lift with a soft dry cloth. On a matte head sculpt, less is more: rubbing makes it shiny, and a shiny spot is harder to fix than a smudge. Collectors restore a matte finish with a light mist of matte varnish, but overspray dulls the glossy eyes, so that is customiser territory.

Paint rub, where one painted part has worn against another or colour has transferred from a neighbouring part, is permanent wear on the factory paint. Touching it up with paint is a repair, not a restoration, and is best left to someone who paints figures.

Conservators do use some solvents, including alcohols, carefully and selectively on materials they have identified and tested. That is not the same thing as wiping a figure with a household product, and the household products below are the ones that do the damage.

Some damage can be stopped from getting worse, some can be disguised, and some can only be replaced. Knowing which is which saves a great deal of heartbreak and a little money.

Pleather that has begun to flake cannot be restored: the coating itself is breaking down. You can stop flexing and warming it, which slows the shedding; you can disguise or repair it; or you can replace the piece and keep the original with the figure’s records.

Cracked rubber and split seamless skin follow the same rule. Plasticiser that has left vinyl or rubber cannot be put back, and adhesives struggle to hold on oily, flexing skin. Repairs on these materials are cosmetic and temporary at best, and the honest long-term fix is often a replacement suit, body or head.

For long storage, return the figure to a neutral pose, take the batteries out, and give it its own space in its tray: soft materials should not press against each other, against hard plastic or against foam and paper they could stick to. Acid-free, unbuffered tissue makes a good wrap for most parts, though anything already tacky may stick to it. Log the spare hands and loose parts in your Vault’s Chests so the figure and its pieces can always find each other again.

Do not seal a figure that is already sticky or smells of vinegar in an airtight bag with nothing to absorb what it gives off; the breakdown products trapped inside can speed up the decay. Do not wrap figures in bubble wrap for storage, and keep wooden and fibreboard boxes away from them. Keep boxes off the floor, away from outside walls, and somewhere with the same cool, dry, steady air as the display.

To move or ship a figure, put it in its tray, the tray in its art box, and the art box in a sturdy outer carton with every gap filled. Never put tape on the figure or the art box itself. Collectors report pleather flaking after summer shipping, so send heat-sensitive figures in the cooler months if you can, and never leave a parcel in a car.

If you are selling, the guide to selling a sixth-scale figure covers packing for a buyer.

Put the tools down when a fix would cut, drill, use a solvent or a heat gun, or touch a face, a circuit or seamless skin; when it cannot be undone; or when the figure is still inside its return window. A figure can always be repaired later. It cannot be un-repaired.

Then ask, in this order: the shop that sold it; the maker’s customer service; a customiser who works on sixth-scale figures; and, for a truly valuable or historic piece, a conservator who works with plastics. Fellow collectors are often the fastest help of all: the Courtyard has a REPAIR SOS for exactly this, and every figure page has an Ask for repair help link that opens it with the figure already tagged.

And if the fix is a new part rather than a repaired one, the guide to parts, bodies and spares knows where to look. Now go and check your batteries, dear resident. I will wait.
