Cover frequently traveled areas of the pool deck with no-slip mats to prevent wear and tear.
Keep metal furniture off of the pool deck. Rust stains from metal chairs can stain your pool deck.
Clean your pool deck frequently with a leaf blower or hose.
Clean up spills as soon as they drop to prevent staining.
Keep your deck area clear of overhanging trees. Leaves and fruit that drop on the deck can stain it.
Likewise, avoid spilling fertilizer on your pool deck. Fertilizer contains iron, which can leave a hard-to-remove orange stain.
Calcium deposits usually originate from grout or setting mortar. To remove, scrape it off the tile. Another method for removing calcium deposits is the pumice stone. Pumice is a light porous glassy lava stone that can be rubbed over a pool stain to remove it. You can get a pumice stone that can attach to your telescopic pole or a pumice stone that has a handle you can swim with.
