Getting through the holidays (and the winter), can leave your fireplace discolored with soot and smoke damage. Did you know smoke film is acidic? Left alone, this buildup will not only continue to discolor the stone, but can cause corrosion as well.
Because marble is a very sensitive stone it is important to take precautions when choosing a cleaning product to avoid etching. Here are a couple quick cleaning tips you can try before having to call a Stone Restoration Professional.
- Start with cleaning the stone with a solution of warm, soapy water using a pH neutral detergent. Be sure the soap does not include citrus or any other acidic agent. Agitate the affected area then rinse thoroughly. If this process does not work you will need try something more aggressive.
- Mix 4 parts water and 1 part hydrogen peroxide. Apply this to the stone surface using a soft plastic or natural bristle brush (this requires very soft bristles so as not to scratch the marble). Scrub the affected area then thoroughly rinse with distilled water until the surface is streak free. Continue to wipe dry using a clean cotton cloth (an old clean t-shirt will do).
- If step 1 and 2 did not work, it is time for the hard stuff — Trisodium Phosphate (TSP). TSP is specifically designed to remove soot and smoke residue. It is a very harsh chemical so it is very important to wear protective clothing when handling. We recommend wearing gloves, protective glasses or goggles, and a respirator. Mix 1/2 cup with a gallon of hot water. Apply with a sponge and rinse thoroughly.
Regular cleaning of your marble fireplace will decrease the need to have the surface resurfaced or resealed.
