I have a copper pipe that has a good coating of green corrosion from a

of something that will remove it? Or do I just need to use some elbow
grease or a drill/wire brush?


Getting it clean won't solve the leak and if it has a leak removing the
patina around the fitting will probably increase the rate of the leak.

Fix the leak first, then worry about the otherwise immaterial corrosion.
