The secret to pool deck cleaning for flagstone is using the right method, not the most pressure. In Post Falls, ID, we match the cleaner and pressure to the surface so it comes out clean without damage. On flagstone, the method we use is low-to-moderate pressure wash.
How we clean it
Cleaning solution: A stone-appropriate cleaner, tested on a small area first.
Cleaning flagstone safely
Flagstone covers several stones, including sandstone, slate, bluestone and limestone, and they react differently to pressure and chemicals. Softer sandstone flakes if blasted, and mortar joints need care.
Avoid: High pressure on soft or layered stone, and acids on limestone.
How often: Every 1-2 years.
