It is crucial to base supplies on gravestone material. It is possible that the gravestone is composed of bronze, granite, or even marble. One must assess their state first. Hard-bristle brushes should never be used on damaged gravestones that are crumbling, flaking or cracked. Do not use bleach, power wash, and scraping as well.

The slate, marble, and sandstone gravestones slowly fade when they are cleaned. They must be cleaned 10 years. For cleaning the gravestone, put it into warm water. Also, you can use a sprayer to clean the water using the pipe. Use non-ionic cleaning detergents to clean granite headstones. The recommended solution should be five gallons of water for every ounce of non-ionic cleaning detergent. Use the solution to gently apply it to the gravestone by using a brush. If you want to ensure that the results are excellent try the solution out first. Scrub the headstone from beginning to end using an easy-bristle brush, while keeping out scratches or flaking areas. Clean the gravestone using a bucket or a hose until the cleaner is completely gone.
