WARNING: the use of spray solvents such as Birchwood Casey Gunscrubber and PowderBlast will severly damage the grips of your P6.
Last night as I cleaned my P6 after its initial trip to the range I looked at the grips and was reminded of my European model P220 that I owned in the Eighties, which got me to thinking. The P6 grips come from a gun from the same period made from what looks to be the same material. With the 220 I used Birchwood Casey GunScrubber and the grips hazed over white and cracked and cumbled in numerous places ruining them. Recalling that I sprayed some PowderBlast on the tip of a rag and dabbed it on a very small area on the inside of a P6 grip panel. Sure enough, it began to eat away at the material leaving black residue on the rag. Eventually it hazed over white.
I can tell you that B-C GunScrubber will definitely ruin the grips. I was a bit surprised that PowderBlast would as well, but polymers in the Seventies weren't what they are now. Even with solvents marked "polymer safe" I'd at least test a small interior area, or better yet just remove the grips from the gun for cleaning.
