Repair Winsor and Newton brush cleaner and blue/green stains?

I've been using Windsor & Newton brush cleaner to remove faceups for more than 10 years. I've used it on resin, vinyl, ABS plastic, among other things. The only time I've had a faceup stain a doll is when I used to do Monster High repaints and I didn't seal the heads well enough. Something about the vinyl really soaked in the red/orange pigments. I got the same results with that type of staining when using isopropyl alcohol & nail polish remover, so I know it wasn't a chemical reaction with the Windsor & Newton brush cleaner.

I would say if the faceup isn't a company faceup, then it's most likely a reaction between the faceup materials- probably because there wasn't enough layers of sealant applied to the doll before the faceup. This is getting into chemistry, which I know next to nothing about. What I *do* know from working at a fine art supply store is that there are lots pigments- some natural, some chemical, some are even carcinogenic. Some colors are more "pure" then others with only one or two pigments, and some colors (cheaper paints or craft store paints) can have a bunch of pigments in them. So even if the color where the stains are weren't painted green, it could be a reaction between the resin and the (most likely) chemical-based pigment.

If it was a company faceup, well.... My only guess is something to do with age? 99 percent of the time, companies seal heads really well before applying faceups. In that case I have no idea.

My only suggestion would be to have another go at cleaning the head with a clean/fresh batch of windsor & newton brush cleaner or isopropyl alcohol (by that I don't mean buy another bottle, just don't re-use the same liquid that had previously been used) and check your cloth/paper towels to see if anything is continuing to come off. Wash well with dish soap and water (I always use Dawn) and let dry. If that does nothing, I would search the customization & maintenance threads to see if someone fixed a similar issue. Basically that was a long-winded way of saying I have no clue, but I hope I could give at least a little insight. Good luck!

 

I agree with @Mainframe110. I've used W&N brush cleaner for ages and never had something like this happen- besides, the brush cleaner is clear so I don't know how it could stain a color. (I have heard that happens with nail polish remover, because some of them have color added.) I'm more inclined to think that the faceup was painted with something that stained.

I'm also wondering what resin color the head is? If the resin is tan, it could be that the head has unevenly faded, which on tan resin has a "greening" effect. One of my tan dolls was very unevenly faded when I got him, and it just looked lighter tan at first, until I wiped his faceup and then the faded areas definitely looked greenish.

 

If anything I'm glad the mystery stain is starting to come off!

 

Tbh that sounds like the head yellowed/greened, and the face-up covered the yellowing really well?

 

I have recently heard someone received brand-new doll with green stain. If you had company faceup at first, maybe the stain was covered under the faceup the whole time. I have been using W&N cleanser for my work and dolls. Never had such problem with resin, wood, glass, natural or synthetic brushes.
If the stain is not too opaque, you may be able to neutralize the green with cool red (blueish red) which is the opposite colour of green, then apply skin tone that is close to other part of resin as possible.

 

Wow! Never seen anything like that!!

From my super optimistic point of view, this is not as bad to coverup. green is overall and is very transparent so you can just cover it up without blending it to normal part! I suggest making pale red based skin tone to cover the greenness. I think a few layers of pastel just do it if you don't have air brush for acrylics. (tho I never used airbrush) FYI Green undertone is actually used on traditional painting method called "verdaccio" to achieve luminous and lively skin tone.I am rather concerned with stains around the eyes.
