Here's what I did:
In a glass baking dish, soak item in water with a generous splash of vinegar for 30-45 minutes. Use just enough liquid to cover. Drain excess liquid.
Mix one packet of Kool-Aid to 1/2 cup of water. Add about a tablespoon of vinegar.
Pour over soaker.
Microwave for two minutes. Rest for two minutes. Microwave for two minutes.
Let cool, then rinse with water the same temperature as the soaker.
Wash with Euculan.
I haven't had any problems with bleeding dye. I used two packets of lemon-lime, but at the time wished I had three.
