In this video, This Old House Kevin O'Connor learns important maintenance tips from stone countertop contractor Jason Keefe.

Steps:
1. Use a white cotton cloth to rub silicone impregnator into stone surface.
Treat limestone and marble four times annually and granite twice per year; engineered stone doesn't require sealing.
2. Wipe up spills and drips immediately to prevent staining.
3. If stains do occur, remove them with limestone poultice.
Spread thick layer of poultice over stain using a plastic putty knife.
Wait 48 to 72 hours for the poultice to absorb the stain, then wipe the area clean.
4. For everyday cleaning, wash stone counters with mild soap and water; don't use citrus-based cleaners or scouring powders.
