To clean a headstone, the general steps are:
- Assess the headstone for any damage such as cracks or flaking. If damaged, consult a professional to avoid worsening it. If not damaged, prepare cleaning supplies such as soft-bristle brush, distilled water, and pH-neutral soap.
- Wet the headstone thoroughly with distilled water to prevent the cleaner from soaking into the stone, which could cause discoloration.
- Apply a small amount of pH-neutral soap to the soft brush and gently scrub the headstone in circular motions, focusing especially on dirty areas. Avoid abrasive cleaners and stiff brushes.
- Rinse the stone thoroughly with distilled water to remove all soap residue.
- Dry the headstone carefully to prevent streaks.
For specific materials like granite, marble, or limestone:
- Granite is durable; tough stains can be treated with granite-specific cleaners but avoid acidic products.
- Marble is porous and sensitive to acids; stubborn stains can be treated with a baking soda and water poultice.
- Limestone is prone to erosion; clean carefully and infrequently, also with a baking soda poultice for stains.
Avoid bleach and acidic cleaners as they can damage the stone. Cleaning is best done in temperate weather to avoid water damage from freezing or thermal shock. Regular cleaning every 12 months is recommended for maintenance. Additional tips include removing plant growth by hand first, using a plastic scraper for moss or lichen, and testing any cleaner on a small hidden area before full use. Always get permission if required by the cemetery. This method honors the memory of the deceased and preserves the headstone's condition over time.
