Maintenance Of Natural Granite Curbstones

Routine Cleaning: Use clean water and a soft-bristled brush or a low-pressure water sprayer to wash away surface dust and fallen leaves. Periodically clear accumulated mud from joints using a high-pressure water sprayer (8–12 MPa, applied at a 45° angle).
Stain Treatment:
Oil/Organic Stains: First, perform a spot test using a neutral cleaner (pH 7–8.5) before wiping the area. For stubborn stains, use a specialized granite rust and yellowing remover (containing mild organic acids or enzymes); let it sit for 3–5 minutes, then scrub and rinse clean.
Rust Spots: Use only a granite-specific rust remover (pH < 1; do not use marble rust removers). Apply locally by dabbing, ensuring the product does not come into contact with plants or metal components.
