I have a Paradisio Bash Granite Countertop in my kitchen. The granite area where the handle of the faucet is located has lost its shine and is rough to touch (seems like it is not sealed anymore). I guess it is because water is constantly in the area. We have hard water, not sure if that matters or not. Is there something I can do to put the sheen back to the granite and make it look like the rest of the counter? Thank you very much for your help.
