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, the Hard Water / Soap Scum Remover we recommend is your best bet... it's specially formulated for use on marble and natural stone (only available in the US).

Best product we've ever found for removing hard water deposits on marble and granite countertops.

Excellent for removing soap scum in showers and baths too.

It's easiest to clean the hard water stains and/or soap scum if you spray on and let sit for 5-10 minutes and then scrub with a soft-bristle brush.

But first, you should remove any large crusty hard water build-up using a plastic scraper to get the bulk of it off.

You may see ammonia suggested sometimes, however, using ammonia will definitely damage marble immediately and if used regularly can damage granite too.

Nearly all common generic and name-brand cleaners are too harsh for use on stone... especially marble.

But all the products we recommend are safe for use on all stone including marble without any damage.

Hope that helps!

Good Luck,
Ryan

See which products I recommend as the best for cleaning marble, travertine & marble maintenance, cleaning granite countertops, granite sealers and keeping all your stone and floors in optimal condition. I've used many good products (Stone Tech, Miracle, MB) but found others more reliable, effective and cheaper too!
