It is really important that you do not clean with anything acidic: vinegar, glass cleaners, or other harsh chemicals. This will break down your sealer extremely fast. And could actually remove the polish from your stone.

We have a great granite care kit that includes everything you need that would be perfect for you. This kit offers a premium professional grade sealer plus a great granite cleaner that will leave the stone streak free, and a super stone polish. This is basically a Pledge for stone. It works great, leaves the stone super smooth, keeps the color rich and bright, and it will continually add sealer into the stone. So by applying this once every couple of weeks, you will not need to reseal your stone.
