We do not: 

• Use equipment such as high-powered gernies or other sand-blasting or high-pressure water-blasting equipment because they can easily damage monument surfaces.
• Use hard wire brushes, steel wool or other harsh abrasives as these can also damage monument surfaces. Scratches in the surfaces will encourage the growth of moss or lichen.
• Use chemicals such as bleach and ‘Gone in 30 Seconds’-type cleaners. These can harm the stone in the long-term. We acknowledge that graves are home to various forms of wildlife, however small, and so we try to take an environmentally-friendly approach.
