Grant, I've found CLR good for cleaning off deposits in faucets, etc. Also Rona, Home Depot, Lowes, and Canadian tire carry both waterproof grease and
silicone grease.
I wouldn't consume water from a faucet where you where you used the grease until I was sure no grease was coming out with the water.
