Remove hard water stains on black granite
Any tips for removing hard water stains on black granite? I contacted a granite care/sales place and they sold me a product specific for this problem - it smelled awful and didn't work. I tried scrubbing, doesn't seem to be helping.
I also have tried to wipe up and water as soon as it spills but in the bathroom there always seems to be some splashed on the counter that escapes me!
Any tips for preventing further stains is also appreciated :)
