Author: LarryLSubject: Quartz Countertop Scaling QuestionPosted: 20 Jan 2010 at 1:35amWhen the plumbers installed my sink faucets - they used regular plumbers putty to seal the hot and cold water faucets. It reacted with the surface and left a ring of white, scaling around each faucet. (I read that there is a non- reactive putty available - but my plumbers did not use it!). How can I restore the counter surface in these small areas that ring the faucet stems?
