Thats what I've heard, its the leaving it on too long that does the damage.
If you just use peroxide as a cleaner, it will cause all kinds of rust. But when you combine it with Murphy's oil soap and alcohol (The MA of MAP), it causes a chemical change that helps the mixture clean easily and thoroughly without causing any rust. I've used MAP exclusively for the last 18-years or so and there's no rust to be found on my rifles. Tried the MA-only part of the MAP once and it didn't work very well. Just mix equal parts of each and you'll be fine.The MAP sounds swell and all . I've heard nothing but good stuff about it. However I'm still leery of one of the ingredients if used by itself. But so far ,on this forum anyway, most everyone seems to think Peroxide is safe to use. I have read where it will take the blueing off of a gun if left for several minutes. I've been assured it will not hurt the gun in anyway, but one cant help but wonder??
I have been using the -40 blue stuff. About 50% methanol with a ph of about 10. Doesn’t hurt automobile finishes, so I don’t see how it could hurt the bore of your gun. Best to check what it does to wood finish. Don’t know if the high methanol content is part of the reason why it works. Don’t usually see the low temp blue stuff available in the Carolinas. Usually rated to 32F. I have purchased what I use up north near the Canadian border (Upstate NY) where I believe all they sell is the low temp formula.I'm contemplating trying WWF as a lube. What I have available is winter de-icer washer fluid. It's not "blue" exactly but more of a bluish purple. Anyone know if this stuff will work? I don't want to damage the bore but it is cheap.
Never thought of using windshield washer fluid as a patch lube, nor ever cleaned my ML with it. I have used windex to wipe with at the range, with great success I might add. I have only ever cleaned with simply water, and likely its the cheapest cleaner.

If deep deep grooves is the answer, what is the question?deep deep grooves is the answer.
