Hhhhmmmm What the HELL!

Funny you should ask, I tend to dislike hosing down the slide with solvents for just those type of reasons.
My primary cleaning solvents are Hoppes (No.9) & (Crud Buster) and Tetra Blaster for hosing out the inside. The outside gets wiped down or rubbed with a T-B wetted cloth and wiped dry. It is possible to have gotten TB on the dots, but not much and not for very long. As a general rule I clean the slide over a trash can holding it vertical or pretty near vertical muzzle up. Unless of course it’s going to a full strip and I’m doing firing pin and extractor too.
