It's CLP not CLR. It is a great general use product but as mentioned not the best solvent for heavy copper or lead build up. I do not see any need to soak overnight with any product unless you have a serious problem.

If I could only have one product it would probably be CLP

I generally just use Hoppes #9 or just Kerosene to clean all the firing /carbon residue and then follow up with a few patches of CLP.

Where was it stated that the Teflon was removed? All my new bottles (Safariland) list Teflon???
