The most important thing to remember when cleaning a tombstone is to be GENTLE. The first priority should be to make sure that nothing you do to a stone will cause harm. 1) Be sure that the tombstone is sturdy and stable, and not wobbly, flaking, chipping, or crumbling. 2) Clean the tombstone with plain water and a soft bristle (natural or nylon) brush. 3) Scrub the stone from the bottom up to avoid streaking and staining. Flush well with water as you go. 4) If lichen is stubborn then soak it well with water and gently scrape with a wooden craft stick/tongue depressor or a plastic putty scraper. 5) Stay away from chemicals and bleach on older stones. While these may provide immediate results, the chemicals may cause deterioration of the stone over time. 6) Don't aim for perfection!
