I have had a fountain in my house for 30 years. I clean it every couple months never had a problem.
I started burning Yankee Candles a couple months ago because they were given to me as a gift and now I'm noticing black everywhere.
I looked at my fountain today and it had black sludge all over the rocks at the bottom of the fountain and coming out the holes in the Fountain arm. The window close to where the candle burns has black residue all over, it's so nasty.
Product or Service Mentioned: Yankee Candle Candle.
