What are the best methods to clean biological growth from stone?
Biological growth such as algae, moss, and lichen can mar the appearance of stone surfaces over time. To restore their beauty, several effective cleaning methods can be employed.
1. Pressure Washing: A high-pressure water stream removes surface growth without harsh chemicals. Use a low setting to avoid damaging porous stone.
2. Vinegar Solution: Mix equal parts white vinegar and water for a natural cleaning spray. Apply, scrub gently, and rinse after 15 minutes.
3. Bleach Dilution: For stubborn growth, a 1:10 bleach-water solution can be used sparingly. Rinse thoroughly to prevent residue buildup.
4. Commercial Stone Cleaners: Eco-friendly enzymatic cleaners break down organic matter without harming the stone’s integrity.
5. Manual Scrubbing: For delicate stones, a soft brush and soapy water can lift growth without abrasion.
Prevent regrowth by improving drainage and sunlight exposure. Regular maintenance ensures long-lasting results. Always test cleaners on a small area first to avoid discoloration.
