How To Avoid Dye Migration: Employing The Wet-White-Cloth Fabric Test
Ignored more than any other tip, this is still the single most essential thing a new doll owner can be told. Colour moving from dark fabric onto the doll's skin is called dye migration, and it's permanent once it has happened. Cleaning items, approaches, scrubbing: none of them, however much you apply, will remove a stain that's been absorbed into TPE. Your only defence is preventing it, and that begins with a straightforward, free test that takes two minutes.

Every Skin Tone Is at Risk
Behind it all sits some uncomplicated chemistry. Like water soaking into a sponge, dye migrates from the fabric into the TPE, because TPE is an oil-based material and dark dyes are typically oil-soluble. Heat and pressure accelerate it. It starts immediately on contact, so a dark dress left on a doll for a few hours in a warm room can cause a permanent stain. On pale dolls dark marks are impossible to miss, so it's particularly visible there, though it happens on every skin tone to some degree.

Cotton Bud, Kitchen Paper or White Cloth
It's an uncomplicated test. Snip a small piece of the fabric from somewhere it won't be seen; an inside seam is ideal. Wet it fully with clean water. You'll need something white to rub against, whether that's a cloth, a cotton bud or kitchen paper, and about thirty seconds of firm rubbing. A trace of colour on the white cloth tells you the fabric will stain your doll, so don't put it on her. A clean white cloth means the fabric is safe, and you can use it without worry.

Water Simulates Moisture on the Skin
The test uses water because water simulates the moisture that's naturally present on the doll's skin, the thing that activates the dye transfer. Less dye transfers from dry fabric on dry skin than from wet fabric on damp skin, so a water test gives you a worst-case scenario, exactly what you want. When the fabric passes the water test, you can treat it as safe for ordinary use. Fabric that fails will stain, and nothing gets around that.

Never Assume a Brand Is Safe
Run the test again for each new piece of clothing, same brand or not. Changing manufacturing processes and varying dye batches mean a fabric that was safe last year might not be safe this year. It takes two minutes, and the payoff is a doll that looks decent for years rather than one with permanent dark marks on her thighs. Skipping it is inexcusable, and customers who learn the hard way are the ones who end up acquiring replacement dolls.

Concentrated, Oil-Soluble Dyes
A slightly waxy or coated feel, a dark colour or a cheap dye each makes a fabric more likely to fail the test. If you want to know the worst offenders, it's black, dark red, dark blue and dark purple, because of their concentrated, oil-soluble dyes. Large amounts of pigment make bright neon colours risky as well. Costly clothing is frequently safer than cheap clothing, though not guaranteed, because cheaply dyed fabric is more likely to bleed than properly dyed fabric.

When in Doubt, Pre-Wash
You'll be safest with light colours, natural fibres and anything that's been pre-washed. Because there's not enough pigment to cause apparent staining, white, cream, beige and pale pastels are nearly always safe. Bleeding is less likely with cotton, linen and other natural fibres, since they tend to hold dye more firmly than synthetics. Pre-washed fabric has already released most of its excess dye, which means it's less likely to transfer onto the doll. When in doubt, pre-wash any new clothing before putting it on the doll.

Some Fabrics Bleed No Matter What
There are a few things to try with a fabric that fails the test before you give up on it. Attempt a number of hot washes with a small amount of white vinegar; the concept is to help set the dye and lessen bleeding. Bind the dye to the fibres with salt, which acts as a mordant, by soaking the fabric in a saltwater solution overnight. Attempt them if you truly want to use a particular piece of clothing; just know they don't always work, and some fabrics will bleed no matter what you do.

Lessening the Risk
The safest choice, if a fabric still fails after washing, is not to use it. A stain on a doll is permanent, and the cost of a new doll is far higher than the cost of replacing a piece of clothing.If you're attached to the fabric and want to use it regardless, there are a few mitigation strategies. A lining of light-coloured fabric on the inside of the clothing puts a barrier between the dark dye and her skin. The other way is to use the clothing for short durations only and take it off immediately after use. Foolproof they're not, but they do lessen the risk.

Cheaper Clothing, Higher Risk
Your safest bet when purchasing doll clothing is vendors who grasp dye migration and have tested their fabrics. Doll-specific clothing brands are normally aware of the issue and opt for their fabrics accordingly, which is why their clothing is more pricey but also more reliable. With generic clothing from high street shops you're gambling, and cheaper clothing means higher risk. Purchasing generic? Invariably test it before use.

How Weather Affects Staining
Another thing worth knowing about is a seasonal factor. Dye migration is worse in warm weather, because heat accelerates the process. There's a risk that a fabric passing the test in winter fails in summer, notably when the doll is stored in a warm room. If it's summer and you're buying new clothing, test it more fully and consider washing it several times before use. The heat of a warm room will cause any residual dye to migrate faster too, so the same applies to storing a doll there.

Once It's Set, It's There for Good
Knowing what the stain looks like, if it takes place, is valuable. Dye migration stains tend to be diffuse and not sharp, because the dye goes through the material instead of staying on the surface. Rather than imprinting a clear outline of the fabric, they show as a general darkening or discolouration of the area. At first it's harder to spot. Over time it's more clear, because the stain spreads and deepens. After it's set, removal is impossible, and the choice is to cover it with clothing or live with it as part of the doll's history.

Test Wet, Not Dry
The testing technique is as significant as the test itself. Thirty seconds can feel long, but a quick rub can miss a slow bleed, so don't skimp. Rub firmly, as though you're attempting to remove a stain, because that's the pressure the fabric will experience against the doll's skin. Fresh cloth for each test, please: a section already soiled from a previous test gives a false result. Don't test it dry; test the fabric wet, since water is what activates the dye transfer.

Start With the Darkest Colour
In a fabric with multiple colours, the darkest section is the one to test first. Light sections might pass while dark ones fail, and the dark sections are what will stain the doll. Unsure? Test each colour separately. Fabrics with dark patterns on a light background need particular care, because the dark parts are the ones that bleed.

How Long Before the Stain Appears?
How long does fabric need to touch the doll before staining takes place? How long? That varies hugely with the fabric, the temperature and the pressure. It might be an hour for some fabrics, or days or weeks for others, before they stain. Fail the test and the fabric is out: the safest approach is to assume it will stain eventually. A little at a time it adds up and never reverses, which is why a fabric that bleeds has no safe exposure time.

Look at the Thighs, Back and Buttocks
If you're buying a used doll, dye migration is worth checking before you purchase. Dark patches on the thighs, back or buttocks are what to look for, as these are the most widespread areas for staining. The stains are permanent and influence the doll's appearance, which is why a doll with noticeable dye stains is worth less than one without. Stains on a used doll mean additional spending on covering them (with clothing or a new body), so that cost belongs in the price and full cost is off the table.

The Wet-White-Cloth Test: Your Best Habit
Single most key maintenance habit for any doll owner: the wet-white-cloth test. What you get for two minutes and no outlay is protection against the most typical cause of permanent damage. In a hurry? Test anyway. Every new piece of clothing, as part of your routine. The five minutes saved by skipping the test could end up costing you a doll. More info at this rosslink.
