The best way to clean and sanitize copper is to use a mild detergent and hot water. You can also use vinegar or lemon juice to help remove any built-up residue.

Can You Unsweat A Copper Fitting?

You likely cannot unsweat a copper fitting. Copper is a soft metal and when it is heated, it can easily form a sweat or seal. The heat from the fitting and the solder will create a permanent bond between the copper and the fitting. If you try to remove the fitting, you may damage the copper pipe.
