I asked the installer if there were any special instructions to cleaning my new granite countertops lombard. I have been saving money for a long time to have my kitchen remodeled so I want to know as much as possible about the products that I have chosen. I certainly do not want to do anything to the countertops to damage them. The installer gave me a brochure that explained the proper care. It also listed a few specific products that could be used for cleaning.
