What is the opinion on Tipton Remarkable? I have tried it recently, to find it is quite strong on copper, and am surprised to not seeing it mentioned.

It is strongly ammonia based and I do not leave it on the bore but a few minutes, using it locally on thespots theat my Hawkeye shows copper after an overnight treatment with Forrest foam, a product locally available and pretty much like WO.

thank you for your comments.
