The information below will help you to understand how to remove organic issues; Such as algae, lichen, mould, leaf staining and bird droppings which affect natural stone gravestones.

Removing organic contaminations from gravestones

Older headstones or just plain matt finish headstones are often sandstone but could be limestone or another kind of local stone. Matt finished honed natural stones often display organic contaminations on their surface. The older the headstone the more likely it will have significantly discoloured.

If the problem you are facing is a dull dark contamination it will probably be organic. This could include lichens, moulds or various algae. Moulds and lichens will often be darker spots or speckles but can also just be a general darkening of the stone. Algae will usually be green but can be red – all are organic so it is possible to remove them.

You can rinse the surface with clean water, or for light applications simply leave the product to dry.

If there are inlaid metals, such as written scripts, made from metals like lead or gold, you can cover this with Vaseline or similar to protect it – Then wipe away after treatment.

General carved writing, inlaid with paints should be fine, other than requiring a quick rinse down with water.

Cleaning & sealing polished marble & granite headstones

The method for cleaning & maintaining highly polished headstones is basically the same. Often a quick overspray of Floorseal Stone Pro is enough to clean off organic issues like algae, lichen, bird droppings & dirt. Cover any metal script and rinse the product off after use.
