Trichlorethane 1.1.1 is similar.


Lacquer thinner was even less effective.

This is polyurethane and there is not much that will eat it.

Dynasolve CU-6 says they can do it but this is pretty nasty stuff.

I accidently tried acetone on a nylon windshirt, (Was going to use lacquer thinner on a stain)It did no harm it may have no harmful effect on other plastics....


On the orig. topic, learned the hard way about sealing conduits when came back to fixtures full of water. Lesson learned.
