Redoing a joint like this which was done OK originally is not

You don't have to clean the pipe end up, just make sure the pipe

originally).

When you get the old joint apart, wipe the end of the pipe with a
slightly damp cloth while the solder is still molten (use a swift
motion, to avoid cooling things down). This will remove surplus
solder
and leave a nice clean tinned end for the new joint. It's similar
to

cleaning the tip of a soldering iron on a damp sponge.

Yep, the only thing that normally hinders a new coupler going on is a
lip of solder at the end of the pipe. I also just heat the end of the
pipe and wipe round with a cotton cloth, although not damp in my
case.


If the joint is in a tight place and or tight up against a wall then a
heat resitant mat might help. It takes the concentration of fitting a
joint like this way from the flames that are burning the wall.
