None of my seven Mosins have ever tasted water, and their bores are still good. Any good bore cleaner (I am NOT including Hoppes #9 in this) will work fine. Hoppes Elite, CLP, the old GI surplus LSA and Milspec "Rifle Bore Cleaner", Birchwood-Casey Bore Scrubber - all work well.
I then follow with a good gun oil in the bore to help prevent corrosion. I live in humid Florida - it works for me.
Ditto for my other milsurps.
Some gun owners get the oddest ideas from the internut.
