Most natural stone is porous, which means it can absorb staining agents in spilled liquids, dropped food and other substances. To protect against staining, most natural stone countertops should be properly sealed and re-sealed as needed.
TIP: Here’s a great way to test whether your countertops need to be sealed. Pour a bit of water on the most-used areas and let it sit for several minutes before wiping it away. If the area where the water was left a dark spot, this is an indication that the stone absorbed the water, and sealing is needed.
Sealing. DIY or Call in a PRO?
This is possible to do yourself, but you may prefer to have your stone care technician do the sealing to ensure proper coverage and the complete removal of any excess sealer which could dull or mar your stone’s appearance.
For routine cleaning you should use a pH neutral cleaner specifically designated safe for natural stone. It is not recommended for you to use vinegar and water to clean your stone. In fact, avoid any cleaner that is acidic or abrasive. Even cleaning your natural stone with dish soap and water can create a filmy buildup and possibly even discoloration, depending on the soap’s ingredients. Using glass cleaner can be even worse, as it may eventually dull the polish. By the way, if you are cleaning mirrors above delicate vanity tops, try to avoid over spraying of the glass cleaner.
Blot spills up immediately. If your stone does become stained, treat it as soon as you can.
Always be careful to use coasters under glasses and clean up spills as quickly as possible. On delicate vanity tops, don’t put perfumes and cosmetics directly on the surface but rather use a pretty tray to display them.
Granite is tough, no doubt about it, but take reasonable precautions. Most natural granite can take the heat, but don’t take unnecessary chances. Use trivets under hot pans.
Try to minimize direct sunlight. UV rays on some stone can result in dulled or discolored areas. This is more in the fillers used on some stone than the stone itself. There are protective treatments that can be done, but simply minimizing the direct exposure should be sufficient in most cases.
We recommend that you have a periodic beauty treatment – a clean, polish and seal service – performed on your countertops by your stone restoration technician.
