QUESTION:
Please advise tips to remove hard water stains on marble and granite as I am facing a severe problem. I am unable to use any chemicals and acids in the market as they may spoil the stone. Please advise with some home tips to use so that the hard water stains can be removed without damaging the marble and granite. Thanks.
ANSWER:
Ravi,
PRISTINE Soap Film/Hard Water Remover is your best bet... it's formulated for use on marble and natural stone (only available in the US) But very often you can remove hard water build-up by simply buffing the area with a super fine grade 0000 steel wool pad.
In a pinch, you could also try a mild ammonia and water solution (1/2 cup ammonia to a gallon of water or 120ml to 4 liters) and soft scrub brush.
If used too much though, ammonia will dull the marble and is not recommended as a regular cleaner
Hope that helps!
Good Luck,
Ryan
