strange black dust/soot on new toilet seat
I know this sounds strange, but in all 3 of my brand new bathrooms, there is a strange black film, almost soot like that keeps appearing on toilet seats and white "wooden" shutters. At first I thought it was the residue from the smoke of candles that were lit, but we stopped with the candles and it keeps reappearing. It is almost as if this dust like substance is being pulled toward smooth, plastic like finishes.
Has anyone ever seen this?? It wipes up easily, but still strange. Any thoughts on what is causing it and how to clean/treat surfaces so it doesn't reappear?
