Hello! Thanks for the replies everyone. Yeah, in retrospect I probably shouldn't have tried coating them with a brand new brand of spray. :( Other than Dettol(what I'm using now) I'm not sure what stripping liquids I have access to. Perhaps simple green, but I'm not too sure.
I'm from Singapore, and the sprays that I've looked at so far are not as cheap as 1-3 dollars. I'll probably dump them back inside the remaining Dettol I have, since more of the minis are floating about in there anyway. I'll start over!
Before that, I'll try with the aceton nail polish remover thingy.
Once again, thanks for the replies guys!
Edit: I used acetone-free nail polish remover and instead of getting rid of the glossiness, it got rid of the paint. Everything went better than expected!
However, there're still hard to reach crevices that have quite some paint buildup, should I rinse my toothbrush in that and just brush it off?
