I know lacquer thinner eats through plastic. Same result. If you try
cleaning with a toothbrush its not long before it looks like you just
killed a centipede with a stick. A great cleaner, wire brush, cloths. WIll
eat the drain, so run water. Takes off dried paint. Evaporates. Supposed
to work for poly-like finishes. I use it all the time. Especially prior to
painting, or for brass hardware covered in paint.
