Pool steps can become stained and unsightly.

Over time, with normal wear and usage, your pool stairs may become stained or discolored. Stains are usually caused by algae or chemicals in the water, such as trace metals. Take care when putting anything in the water to clean the stains that could change the chemistry of the water or be unsafe for swimmers, but there are several ways to remove pool step stains without causing damage to the surface or the water.


Step 1

Rub a chlorine tablet directly on the pool stairs. Wear rubber gloves to protect your hands and use plenty of pressure. If the stain remains, rub the stains again with the chlorine tablet and then scrub the stairs with a tile scrubber. This may take time to remove the stains.

Step 2

Soak a rag in liquid chlorine and scrub the stairs. The chlorine will disperse into the pool quickly.

Step 3

Add 15 oz. of commercial pool stain removal to your water for every 10,000 gallons. Apply weekly to prevent and remove stains. Scrub the stairs with a tile scrubber after application.

Step 4

Take a sample of pool water at least 6 inches deep from the pool using the sample collection tube from the pool water test kit. Dip the enclosed test strip into the water. Compare the test strip with the enclosed chart. Dissolved solids should not read above 1,500 ppm. For levels above 1,500 ppm, add 1 lb. of ascorbic acid for every 10,000 gallons of water. Retest the water. Reapply if necessary. This will prevent more staining.
