Hi, sorry I have missed this question? I looked it up before and the answer is simply NO, WD 40 is not good for potentiometers. There are additives that can cause problems.

What's the solution that you used to clean the circuit?

It was a contact spray. Not really cleaning, just adding conductive oil :) EDIT 2022: the contact spray is NOT conductive. Also never try to look for conductive grease/oil whatever. The purpose of the oil/grease is to protect the contacts. The contacts will push the oil away, thus a good contact is preserved.

With potentiometers there are several possibilities for problems: the resistive coating has worn out (the wiper has scratched it), the coating is cut, connectors are loose on the circuit board (resolder to fix). Or, in case of corded controls like this, the cord is broken.

I did not have my own experience, so I looked it up. The general opinion is that WD 40 is NOT suitable for potentiometers. It may work, but it's not a good lubricant nor cleaner, it leaves a residue that attracts dust and dirt. I read several opinions on this and it is clearly not recommended.

How to replace it

It's usual there are no spare parts for these. The potentiometer should be a standard part, but need to find it somwhere, then solder the old one out, new one in, and move the thumbwheel, if it's removable. Of course the whole thing can be re-built completely, it's just a volume control and a power switch, but that's electronics and I cannot get into details here really.
