I gotta agree T.Baggins, I tried it a decade or so ago on Dirty Bong, and the plastic started turning a funky white sorta color, and I washed it off.
I tried 420 grunge remover. It too, made the acrylic react. Also left a funky orange flavor in that plastic that was hard to get out.
I gave up getting it sparkling clean long ago, but the Olive Oil works SUPER! I can see the water in there for the first time in ages....
