Anyone else using Ballistol to clean there Glock? I bought some and I have to say its great stuff. I've been using it on my Gen4 to clean, and Gun Butter to lube. Last night when I was done cleaning my Glock I took two brushes that i've been using to brush down the frame with. They were both black. I sprayed Ballistol on both waited a few min and ran them under water and both were white again. There are many video's on Youtube.
