Cleaning Plenum - Any New Ideas
I know the consensus has been to use a whitening toothpaste, but I was wondering if anyone has come up with something that might work better. Or maybe I'm not using the toothpaste correctly. I put it on a dampened soft cloth, rub lightly and then use a dampened clth to wipe it off with. I also tried a clay bar (no bueno).
