I would encourage you to take a drive over to Greenspace in Santa Cruz to look at their very unique options available.
While we would love to clean and maintain your Granite and Tile counter tops in the future, you really should look into the great “green” products that the fine folks @ Greenspace has to offer..

Make sure to pick up some Neutral pH cleaner for your kitchen while your there.
Tell them Connoisseur sent you.
