What to use to clean PVC Threads and O'ring Face Seals

[laprjns]

I'm going to be reassembling my plumbing when I open over the next few weeks. I will not ask about tape versus pipe dope but what do you use to clean off old tape, pipe dope and o'ring lube? Is there a solvent that will clean them off without damaging the PVC pipe?

Thanks
Rich

It usually comes right off, although I have used a plastic knife to scrape off old pipe dope and silicon caulk. A good stiff bristle brush will probably work as well.

I have used an old toothbrush and it worked pretty well.
