I got a couple guns from my grandpa that were in bad shape, I took them all apart put the pieces in the oven and then scrubbed them with this stuff, it cleaned them up great.

Most of the time though I just use it to clean like you normally would. Give it a good scrubbing and a good coat and it's good. It also makes them a lot easier to clean the next time.

I use both the liquid and the paste.

It smells good, it's non-toxic, it works great I have no complaints about it at all.
