The kitchen is dirtier than most bathrooms. A kitchen worktop has about 10 times more bacteria than a toilet seat! Near the drain there are about 3,000 bacterial per sq.cm. Without nutrients and water, bacterial cannot grow. An impregnating sealer will make the countertop highly water and oil repellent. This doesn't mean that the surface won't get dirty, but it will impede water and oil based liquids from penetrating into the pores and causing a permanent stains (the ones germs cling onto), making the countertop easier to clean and more hygienic. Even once impregnated, natural stone still needs to be correctly cared for. STAIN-PROOF^® has created a new Countertop Care Sheet, a simple guide to caring for natural stone countertops which can be printed off and given to customers. STAIN-PROOF Daily Countertop Cleaner is a gentle daily cleaner designed for natural and engineered stone countertops, which contains a touch of sealer so an extra layer of protection is added over multiple cleanings.
