<P style="MARGIN: 0px">Be careful with Gun Scrubber around plastics. Most are not harmed by it, but a friend of mine, back in the late '90's sprayed the trigger assembly of his 3" Charles Daly semi auto with it and dissolved it. It looked like someone had played a propane torch across it, it was so badly melted. I don't know if Charles Daly is using the same plastic to make their trigger guard assemblies, or if Gun Scrubber has the same formulation as it did back then.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">Also, I have seen problems with some of the solvents damaging plastic magazine followers, my BPS12 and BPS10, in particular. They must have had Charles Daly plastic in them.<IMG src="http://www.websitetoolbox.com/images/boards/smilies/wink.gif" align=absMiddle border=0> Don't just shoot the stuff down the magazine tube until you have removed the follower, if it is plastic. Otherwise, Gun Scrubber is great stuff. </P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">Carb cleaner and brake cleaner work, too. However, Carb cleaner will potentially harm some plastics and finishes. It is better used away from both. Brake cleaner is not as aggressive a cleaner as carb cleaner, and has not seemed to harm plastics or finishes on the guns I have.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">All of these cleaners will strip the oil off metal, so make certain you adequately reoil to prevent corrosion after using any of them.</P>
