Help with yoyo dye

So I’m looking to dye one of my yoyos. Does it matter if I use liquid RIT dye, or does have to be powder?

Thanks!

So I could be wrong on this but I was told that rit dye no longer works well for yoyos because it was reformulated.

I don’t think that is true, at least I’ve not seen that. Another though issue is the type of plastic. You can use a water, dye acetone mix on polycarbonate, but delrin requires just water.

I’m not surprised if I was wrong. I am speaking completely from what others have told me, no actual, personal experience.
