Dark fabric can transfer colour onto the doll's skin, a process known as dye migration, and the effect is permanent. Cleaning items, techniques, scrubbing: none of them, however much you apply, will remove a stain that's been absorbed into TPE. Your only defence is avoiding it, and that commences with a straightforward, free test that takes two minutes. Heat and Pressure Speed It Up It all comes down to chemistry. Dye behaves like water meeting a sponge here: TPE is oil-based, dark dyes tend to be oil-soluble, and so the colour is drawn out of the fabric and into the TPE. Leave a doll in a dark dress for a few hours in a warm room and that's enough to cause a permanent stain, as the process starts immediately on contact. It happens to some degree on every skin tone; on pale dolls, though, it's particularly noticeable because dark marks are impossible to miss. Rub It Against a White Cloth for Thirty Seconds The test itself is uncomplicated. Clean water, and plenty of it, goes on a small piece of the fabric that you've taken, ideally from an inside seam where it won't be seen. Then take a white cloth, a cotton bud, or a piece of kitchen paper, and rub the wet fabric firmly against the white cloth for about thirty seconds. If any colour transfers to the white cloth, the fabric will stain your doll, and you should not put it on her. When the white cloth stays clean, the fabric is safe to use, without worry. Fail It and It Will Stain Dye transfer is activated by the moisture naturally present on the doll's skin; water simulates that, consequently its use in the test. You want a worst-case scenario, and testing with water gives you one, because wet fabric on damp skin transfers more dye than dry fabric on dry skin. Fabric that gets through the water test is safe for typical use. Should it fail, it will stain, and that's that. Two Minutes vs Permanent Marks on Her Thighs Same brand as last time? Repeat the test for every new piece of clothing regardless. Changing manufacturing processes and varying dye batches mean a fabric that was safe last year might not be safe this year. Permanent dark marks on her thighs are the alternative to a doll that looks solid for years, and the test that decides it takes two minutes. Replacement dolls get bought by the customers who learn this the hard way, and there's no excuse for skipping the test. Concentrated, Oil-Soluble Dyes Expect failures from dark colours, cheap dyes, and anything with a somewhat waxy or coated feel. Pay most attention to black, dark red, dark blue and dark purple, the worst offenders, whose dyes are concentrated and oil-soluble. Hazardous as well are bright neon colours, with their large quantities of pigment. Cheaply dyed fabric is more likely to bleed than properly dyed fabric, so pricey clothing is often safer than cheap clothing, though the difference isn't guaranteed. Why Natural Fibres Bleed Less The safest fabrics are the light-coloured ones, the natural fibres, and anything that's been pre-washed. Because there's not enough pigment to cause evident staining, white, cream, beige and pale pastels are almost always safe. Bleeding is less likely with cotton, linen and other natural fibres, since they tend to hold dye more firmly than synthetics. Fabric that's been pre-washed isn't carrying as much excess dye, having already released most of it, and so is less likely to transfer onto the doll. Before putting any new clothing on the doll, pre-wash it when in doubt. Worth Trying for a Favourite Piece There are a few things to attempt with a fabric that fails the test before you give up on it. Setting the dye and cutting down on bleeding is what several hot washes with a small amount of white vinegar can do. Salt binds the dye to the fibres, acting as a mordant, so leaving the fabric in a saltwater solution overnight can also help. Try them if you really want to use a specific piece of clothing; just know they don't consistently work, and some fabrics will bleed no matter what you do. Neither Is Foolproof A fabric that still fails after washing is best not used at all; that's the safest option. Weigh the two: a stain on a doll is permanent, and a new doll costs far more than replacing a piece of clothing.You might be attached to the fabric and want to use it regardless; if so, a few mitigation strategies are there. Put light-coloured fabric inside the garment as a lining, producing a barrier between the dark dye and the doll's skin. The other way is to use the clothing for short periods only and take it off immediately after use. The risk is lessened by both, though neither is foolproof. Purchasing Clothes for Your Doll Seek out retailers who comprehend dye migration and have tested their fabrics when you're purchasing clothing for a doll; it's the safest approach. Their clothing is more expensive but also more reliable because doll-specific clothing brands are normally aware of the issue and pick their fabrics accordingly. A gamble is what you're taking with generic clothing from high street shops, and the cheaper it is the higher the risk. Generic clothing should always be tested before use. Dye Migration Is Worse in Warm Weather One more thing worth knowing about: a seasonal factor. Warm weather is bad news for dye migration, as heat accelerates the process. Passing in winter proves little, since the same fabric might fail in summer, particularly if the doll is stored in a warm room. If you're buying new clothing in summer, test it more fully, and consider washing it several times before use. The same applies if you're storing a doll in a warm room, because the heat will cause any residual dye to migrate faster. What a Dye Migration Stain Looks Like It pays to grasp the stain itself, if it occurs. Spreading through the material instead of sitting on the surface, the dye makes dye migration stains normally diffuse rather than sharp. Rather than imprinting a clear outline of the fabric, they show as a general darkening or discolouration of the area. As the stain spreads and deepens, it goes from hard to spot originally to more clear over time. There's no fixing a set stain, so you either cover it with clothing or accept it as part of the doll's history. Test Wet, Not Dry Testing technique matters every bit as much as the test. Stick with it for the thirty seconds of rubbing; a quick rub can miss a slow bleed. Soft won't do. The fabric will be pressed against the doll's skin with genuine pressure, so rub firmly, as though you're attempting to remove a stain. False results come from cloth already stained by a previous test, so use a fresh section of the white cloth for each one. Don't test it dry; test the fabric wet, since water is what activates the dye transfer. Light Sections Can Pass While Dark Ones Fail If you're testing a fabric with multiple colours, test the darkest section first. Failing on the dark sections is possible even if a fabric passes on the light ones, and the dark sections are what will stain the doll. Watch fabrics with dark patterns on a light background especially closely; the dark parts bleed. When unsure, test each colour separately. Assume a Failed Fabric Will Stain Eventually There's the matter of how long a fabric needs to be in contact with the doll before it stains. The fabric, the temperature and the pressure decide it, and the answer varies vastly. Days or weeks are what others take, while some fabrics will stain within an hour. No gambling on a failed fabric; the safest approach is to assume it will stain in the end and avoid it completely. The bleed is cumulative and irreversible, so there's no safe exposure time for a fabric that bleeds. Look at the Thighs, Back and Buttocks If the doll is used, dye migration is worth checking before purchase. Dark patches on the thighs, back, or buttocks are the signs to look for, being the most common areas for staining. Dye stains that are visible are permanent and influence the doll's appearance, so a doll with them is worth less than one without. Never pay full price for a soiled doll. Instead, factor the cost of covering the stains (with clothing or a new body) into the price when acquiring used. Final Word on Dye Migration The single most major maintenance habit any doll owner can develop is the wet-white-cloth test. Cheap it is not; free it is, and two minutes later you've prevented the most widespread cause of permanent damage. Skipping it because you're in a hurry is a bad habit, so make it part of your routine and test every new piece of clothing. Skipping the test saves you five minutes, which could cost you a doll.
