What's your mix?

For dye?

I used 32oz water, 4ish dish soap, and 4ish of acetone.

rit and water. I add more rit as I see fit. I doubt having acetone in there will do you much good after the first dye- that stuff is very volatile and evaporates away rapidly.

I heard that increasing the acidity will make the colors brighter, but haven't done any good scientific testing of it.

Lemon juice already does a million other nifty things..may as well throw it in a dye mix and find out.

I've been adding some cider vinegar to my Scarlet rit, and the only difference I have noted that stands out is the pan smells like vinegar.

I'm talking about an actual methodic experiment.

If I had any scrap plastic I'd give it a go, but the only discs I could dye are already dark colors. When you say "actual methodic experiment" do you mean having a few different baths with the same concentration of dye and the main difference being a pH of 3, 5, and 7?

exactly. All variables constant except for pH.

So Rit is thee dye, but has anyone found a better dye? One with less fade/bleeding? I have heard Metal Complex dye, as well as fast milling dye might work better on polyurethane than rit. Any experimenters out there?

Here are some of my recent dyes:
