Try regular toothpaste, not the gel kind.

Don't know if it will work on granite but I used toilet bowl cleaner on a fiberglass sink that had a lot of hard water stains, mostly lime build up & it took it right off.

1ST TRY A RAG SOAKED IN VINEGAR LET SIT ON THE STAIN FOR 5-10 MIN MAY NEED TO DO MORE THAN 1 TIME TO COMPLETELY GET IT OFF.

White vinegar is the best choice for water residue on a counter-top. Toilet bowl cleaner might work, but many contain muriatic acid which could etch natural stone.

Years ago, I had a client who owned a laundry-mat. He used a scrubby-sponge dipped in Downey to clean the hard water spots off his equipment. Try it, at least it won't hurt your granite or your hands.

Never use vinegar, Toilet bowl cleaner, lemon anything acidic. Use a pumice powder. Better yet read the cleaning guidelines. Also never use home made cleaning ideas. Granite is a porous stone, It can last forever if taken care of right. I am linking the marble Institute of America cleaning guidelines on stone. Please read this before you decide to pour toilet bowl cleaner on such a expensive surface. http://www.marble-institute.com/stoneprofessionals/commercial_care_clean.pdf

Buy food grade citric acid from amazon.com. mix 2 tbs in a spray bottle with water. Spray and let sit 2 minutes. It will literally wipe right off and will not damage granite or the polished finish/sealer. This also works amazingly on glass shower doors and any tile.

You can buff the hard water stains from the surface by using steel wool. Alternately you can also use a fresh razor blade to scrap of the hard water stains. It is very important that you wear gloves when you are using grade steel wool.
