The most important step in insuring that your counter tops stay clean and beautiful is ensuring they are properly sealed. Granite is a very hard surface and less porous than marble. Unsealed or poorly sealed granite will soak up liquids, oils, stains and helps prevent bacteria growth. Checking that your granite is sealed properly is easy. Place a few drops of water on the surface of the counter for 5 minutes. If it beads up, you have a good seal. If after a few minutes the water has soaked into the granite, then it’s time to reseal the stone.
With a good seal granite is very easy to clean and maintain, that is one of the benefits of these counter tops. Typically, a rag and warm soapy water is all you will need to maintain clean bacteria free counter tops on a daily basis. If you require something a little stronger after raw meat or other bacteria hazards, try a mixture of 50% isopropyl alcohol and 50% warm water.
Do not clean with.
Harsh or abrasive cleaners and sponges, acidic cleaners like vinegar, lemon, lime, or anything with ammonia or bleach. Frequent use of harsh chemicals and abrasive scrubbers will dull and weaken the sealant over time.
