Nice to use. Just don't expect miracles, and be realistic. Heavy crud may require some scrubbing. I use it in conjunction with my other cleaning supplies.
The foam action of this product really helps clean out the lead in the Ruger 10/22 rifles especially when using dirty ammo. Put some foam and let it do its work while you clean the rest of the gun. Come back with a rod and some patches or a Viper snake and you are done. It really cuts down on the time on having to clean the barrel. Have been using it for 2 years now and LOVE it!
stumbled upon the Hoppe's foam bore cleaner looking for the old standard Hoppe's solvent cleaner. thought I'd give it a try with my rifled barrel 12 ga slug shotgun. It worked really slick, no mess no fuss. With the solvent cleaners, a spill of the slightest drop always leaves behind an odor. The foam cleaner had no spillage, no left behind odor. great new product.
