Granite walkways, pavers, steps and headstones can gather all types of dirt, stains, moss, mold, algae and mildew overtime. Maintaining this soft mineral will not only help make it look better aesthetically but help preserve it and last longer as well. Unlike many other types of stone, granite is a hard stone that can tolerate cleaning without damaging the surface or making it susceptable to further damage down the line, thus explaining its broad usage outside. Below is what you need to tackle this as a do it yourself project.

What you Need to Clean Granite

• non-ionic cleaner
• 5 gallon bucket
• water
• non-metallic soft tip brush
• pressure washer

Steps to Pressure Wash Granite

1. Begin by examining the granite to inspect for signs of cracking or flaking. If these areas are found put as little stress when cleaning the area as possible.
2. Place plastic tarps around the surrounding area to avoid damaging any nearby vegetation.
3. Add a non-ionic cleaner to a few gallons of water in your bucket and apply to the entire area.
4. Using a non-metallic soft tip scrub brush or sponge brush the entire area, not just the visibly dirty areas.
5. Use a powerwasher with little to virtually no pressure to rinse the entire area carefully from a few inches away. It is not the pressure of the water that will clean the granite, it is the angle of the pressure washing tip that does all the work.
