Fireplaces add warmth, value and aesthetic appeal to homes. The heat resistance, durability and longevity of limestone make the natural stone ideal for fireplaces. Limestone is available in many natural colours to enhance and accommodate individual styles. As with all fireplace surfaces, limestone fireplace fronts accumulate dirt and grime, which cause them to appear dingy. Regular cleaning prevents limestone from becoming scratched due to abrasive grit particles. Fortunately, simple solutions can effectively clean limestone fireplace fronts.
Lay plastic dust sheets around the perimeter of the fireplace to protect the floor from cleaning solutions.
Brush the limestone with a whisk broom to loosen dirt and grit particles. Vacuum the front of the fireplace with a vacuum attachment to remove any remaining particles.
Fill a spray bottle with warm water and a couple drops of mild liquid dish soap. Mix the solution thoroughly. Fill a plastic bucket with warm water, for rinsing.
Spray the solution onto a one-by-one-foot section of the limestone. Scrub the limestone with a nonabrasive sponge to remove dirt, grime and residue.
Dampen a microfiber cloth in the bucket of warm water. Wipe the damp cloth over the soapy limestone to rinse away the soap and grime.
Wash the remaining one-by-one-foot sections of the limestone surface using the same techniques. Frequently refill the plastic bucket with fresh warm water to prevent reapplying dirt to the stone surface.
Dry the entire limestone surface with a terrycloth towel. Fold up the dust sheets and remove them from the area.
You can substitute stone soap for the mild liquid dish soap. Remove stubborn stains on limestone with ready-made poultices.
Do not use vinegar, lemon-based cleaners or other acidic products; the limestone surface may become etched. Do not use scouring powders, steel wool, wire brush or other abrasive products; the limestone surface will become scratched and possibly permanently damaged.
