LOL, I wasn't quite sure what that reply was telling us. Thanks for the translation.
Not sure why Easy Off was needed. We usually use that stuff (lye-based chemicals) to safely strip paint from plastic model bodies. I would imagine that lacquer thinner or acetone would also work well for removing dried up paint in mixing bottles. Whether those are plastic or glass, they should be resistant to either of those chemicals, and would I rather mess around with lacquer thinner or acetone, than with lye.
