I use them. They work much better than silicon cloths. I use them on all my working guns.
I also use them in the chambers of my guns. Works wonders on finicky rimfires and makes cleaning simpler.
Thanks pilgrim. Do you use the marine or the other? I have the marine cloth and the 1/2 oz. bottle...not sure how to use the liquid on the guns, but the cloth work good on my high end knives.
I use the Marine cloth.
When new the cloth leaves a haze, that I rub in with a soft cloth.
If you store the cloth in a small glass jar, they'll last a long time.
