I was reading your suggestion on the fabric dye page for spandex blends. I have a Spider-Man suit that I believe was made through dye sublimation. I want to change the color of it for a new costume idea since it is a spare and I’d rather use the money for this project. I understood from the manufacturer that it is a spandex-polyester blend.
Originally, I was going to buy Dye-Na-Flow and get to work, yet I realized that it would be better to remove the existing dye. Which dye remover will work best for this?
Bad news here. It’s unlikely that any dye remover will restore your costume to a colorless condition. Some dyes can be removed, some can be lightened or turned to an unpleasant surprise of a color (such as black turning to orange), and some dyes cannot be removed at all; among the dyes currently coloring your costume are probably some of each.
What’s worse, trying to remove the dye is likely to damage the material. Spandex, the stretchy fiber which enables your costume to be close-fitting, really hates heat. All reducing-type dye removers require high heat. Oxidative bleaches such as chlorine bleach will destroy spandex and will turn polyester an ugly dull yellow color.
What I’d encourage you to do instead is find an inexpensive long-sleeved unitard, something like this item:
Unitard Men’s Zentai Bodysuit with Eyes Open
…in either white or a suitable color, keeping in mind that you can easily make it darker or more intense in color, but not lighter. Then go ahead with your Dye-Na-Flow fabric paint. Whatever fabric color you choose will show through any lighter color of paint or dye that you apply; you can apply an opaque color on top of it, such as Neopaque fabric paint, but there will be some slight change in texture, so that’s more suitable for details than large areas of color. (I’m not recommending that specific item, just the concept; make sure that it comes in a size large enough for you. Try a dance supply store if you can’t find it elsewhere.)
