So I cleaned a few guns recently. A couple AR’s and a couple Glocks. Both had some carbon build up and stuff on them. I’ve got Hoppe’s #9, Rem oil, Ballistol and all seemed to do well at getting the loose stuff off, but all seemed to require a lot of elbow grease to clean off of the caked on areas. I sprayed on, let sit for a few mins and hit with a brass or plastic brush or both. Looking through the cleaning threads here, it seems like Hoppes #9 gets a lot of votes, but I’m not that impressed. To get my G19 feed ramp clean, I had to soak it in a shot glass multiple times and scrub, scrub, scrub. I don’t care about the work, I’m a farm kid. But most people seem to act like it’s a 5 minute process start to finish and it seems like I struggle to truly get a Glock feed ramp or an AR bolt carrier nice & clean. Anyone have any other solvent suggestions? FYI, I use Gun Butter for lube. It’s a little thicker and it comes in a container almost like Loctite and has like a hypodermic needle applicator. So it’s super easy to get a very small amount in a very specific location.
