Key Takeaways
- Vinegar and baking soda tackle stains and algae without toxicity.
- Hydrogen peroxide kills mold and brightens discolored stones.
- Pressure washing works for deep cleaning but requires caution.
1. White Vinegar Solution
White vinegar is a powerhouse for dissolving mineral deposits, grease, and algae. Mix equal parts vinegar and water in a spray bottle, apply to stains, and scrub with a stiff brush. For heavy moss, use undiluted vinegar. Rinse after 15 minutes to avoid etching sensitive stones like limestone. Pair it with our scented vinegar solutions for a fresher finish.
2. Baking Soda Paste
For grease or oil stains, make a paste with baking soda and water. Apply it thickly, let it sit for 30 minutes, then scrub. Its mild abrasiveness lifts grime without scratching. Combine with vinegar for fizzy, deep-cleaning action.
3. Hydrogen Peroxide
A 3% hydrogen peroxide solution kills mold and mildew. Spray it on damp stones, leave for 10 minutes, then rinse. For tough stains, mix with dish soap for extra lifting power. Avoid using on colored stones to prevent fading.
4. Lemon Juice
Lemon juice bleaches stains naturally. Mix with salt for a scrubbing paste or dilute with water for general cleaning. Ideal for light-colored stones, but test first to avoid discoloration.
5. Pressure Washing
For large areas, a pressure washer (under 1,500 PSI) blasts away dirt. Hold the nozzle 12 inches away to prevent damage. Pre-treat with vinegar for better results. Not recommended for soft stones like sandstone.
6. Castile Soap
Mix Castile soap with warm water for a gentle, plant-safe cleaner. Effective for routine maintenance without harsh residues. Add essential oils for fragrance.
7. Oxygen Bleach
Unlike chlorine bleach, oxygen bleach (sodium percarbonate) brightens stones without harming plants. Dissolve in warm water, apply, and rinse after 15 minutes.
