Bought a small bottle of this at the Costa Mesa gun show and was totally amazed at the way this stuff works. I use less and it doesn’t smell up the house. Nice thing about it is that it does not evaporate. You can leave it on overnight and allow it to penetrate the fouling and it makes it easier to clean. It doesn’t dry out my hands if it gets on my skin like a lot of the other cleaners do. Being non toxic and biodegradable is a nice feature of the product. I would highly recommend this product to anyone. Awesome stuff!
