Moss and lichen are very common on graves in the UK, especially in older cemeteries. While they may appear unsightly, they are a natural result of the environment — and removing them incorrectly can damage the headstone.

Why Moss and Lichen Form

Headstones are ideal surfaces for moss and lichen because they are:

• Constantly exposed to moisture
• Often shaded by trees or walls
• Made from porous stone
• Rarely disturbed or cleaned

Lichen, in particular, grows slowly and bonds tightly to stone surfaces, especially softer stones.

Are Moss and Lichen Harmful?

Over time, yes. While they start as a surface growth, moss and lichen:

• Trap moisture against the stone
• Encourage frost damage in winter
• Slowly break down softer stone surfaces
• Obscure inscriptions and carvings

That said, aggressive removal can be far more damaging than the growth itself.

How Moss and Lichen Should Not Be Removed

Avoid:

• Scraping with metal tools
• Pressure washing
• Bleach, vinegar, or acidic solutions
• Hard brushes or abrasive pads

These methods can permanently scar the stone and accelerate decay.

Safe Removal Methods

Safe moss and lichen removal involves:

• Low-pressure, stone-safe techniques
• Soft plastic scrapers, and nylon brushes
• Specialist biocidal treatments designed for memorial stone
• Careful, gradual cleaning over multiple stages if needed

This approach removes growth while protecting the stone’s integrity.

When to Seek Professional Help

If moss or lichen has been present for many years, or if the stone is sandstone or heavily weathered and stained, professional cleaning is strongly recommended. A trained approach ensures the memorial is preserved — not slowly destroyed.
