I have never had a problem in all the years I have been shooting a ML cleaning with hot soapy water even use the dollar store dish soap. the cheapest cleaning solution I have ever found. Like any thing in life if done correctly it works and removes every thing in the bore. The water isn't tap water hot at 120F either, It is scalding hot off the stove.
I only use real black and triple 7 in my rifles.
