Cleaning Methods: Application Only - Highly effective for all stone and masonry. No brushing or rinsing required; rain provides natural rinsing. Recommended for fragile or eroded stones. Saturate stone from top to bottom with Gravestone & Monument Cleaner. Cleaner percolates deeply under the surface for long-term effects. Water reactivates cleaning action, from rain, dew, or misting. Application, Brushing, and Rinsing - Suitable for stable stones, especially modern granite monuments. Saturate stone with cleaner. Let dwell on surface for 15 minutes Remove loose lichen with a soft plastic scraper, if needed. Lightly brush with soft-bristle brushes. Mist with water to keep surface wet while brushing. Rinse thoroughly with potable water. Coverage: Ranges from approximately 200-400 sq ft/gal (Coverage will vary depending on the porosity of the surface) Important Note: Thoroughly saturate surrounding grass and plants with water to minimize absorption and provide protection from cleaner. The stone may temporarily change colors, most commonly orange, red, or black. This is called the blushing effect. The discoloration will fade within a few days without rinsing and is not harmful to the stone.
