Sorry for such a simple post but I cannot find a definitive answer to this question. I will be removing an old existing Brasscraft multi turn compression stop valve and installing a new DAHL 1/4 turn compression valve for a toilet. The existing copper pipe is 20 years old and definitely does not look "clean". My dilemma is the instructions say to clean the pipe but do not say what I am supposed to use and I have read where some more aggressive cleaning can result in scratches deep enough in the pipe to cause a leak. So the question - what do I use to clean the pipe, if anything? I have seen suggested : Scotchbrite pad (not sure that would even do much but what kind pad there are many varieties) , Emery Cloth (comes in various grits, which grit? some say emery is too aggressive and can cause leaks), Steel Wool (same say do, some say don't use), I have a "Blue Monster 6 In 1 Fitting and Tube Deburring Reamer" that has steel brushes for cleaning a pipe , etc, ? I know cleaning for soldering is a different animal vs cleaning for compression but presume I should do something to clean it.
Thanks!
Thanks!
