When North Coast Tile & Stone fabricates and installs granite counters, we seal the stone 2x with a penetrating stone sealer. These stones should be re-sealed every year with 511 Impregnator Pro or Dupont StoneTec Impregnator.  These sealers will not change the color of the stone. 

*This sealer will help prevent stains from setting into your stone counter. It will allow water transmission – so a cold glass of water will leave a moist ring and will dry over several hours. This will not damage or permanently affect your stone.
*Marble, Travertine and Limestone can be affected by acids. Citrus, Beer, wine, liquors, and vinegar will also cause etching (dulling of polished finish).
*Wipe up spills and drips as soon as you notice them.
*This stone is more porous and can scratch more easily

DO NOT USE:

• Citrus-based cleansers
• Ammonia-based cleansers: Dawn, Windex
• Vinegar
• Bleach or bleach wipes
• Harsh chemical cleansers (409, Comet, Soft Scrub, TileX, etc)
• These products will slowly remove the sealer used.

PLEASE USE:

• Gentle Ph balanced cleansers
• Stone specified cleanser
• Liquid Ivory Soap and water
• Simple Green (diluted)
