Cleaning Plastic Crud off Pipes.
To get Plastic crud that has melted onto your pipes, we offer the following suggestions:
For really thick stuff:
a Canadian penny or other all copper coin.
a razor blade. (be careful not to nick the chrome!)
For semi-thick stuff:
#0000 steel wool. (be careful, steel wool may scratch.)
For just about every kind:
Turtle Wax Chrome Polish and Rust Remover
Mother's Chrome Polish
For everyday cleaning of chrome and glass:
Glass Wax in the Pink Can, Excellent stuff!
