What Do You Clean Copper Pipe With Before Soldering?

You should clean copper pipe with a wire brush to remove any oxidation or dirt and then apply flux to the pipe and the solder.

How Do I Clean And Sanitize Copper?

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.

To Summarize

Removing solder from copper pipe can be a difficult task. If the solder is not too old, it can be removed by using a propane torch to heat the pipe until the solder liquefies. The solder can then be drained from the pipe by using a plunger. If the solder is too old or has been attached to the pipe for a long time, it may be necessary to use a hacksaw to cut through the solder.
