Cleaning a pool liner is a task every pool owner is faced with at some point or another. Pool owners use pool liners to protect the interior surface of their pools from environmental and man-made hazards. But these liners, whether they are in ground pool liners or above ground become stained from the buildup of residue or other grime they are exposed to and need to be cleaned from time to time to maintain the look and condition of the pool.  

Follow these steps on how to clean stains from your pool liner. 

Step 1: Drain the Pool

You must drain the pool before starting the clean up process to make sure you clean the entire liner, without leaving any part behind. Follow the directions on your manufacturers handbook to drain the pool properly.  

Step 2: Remove the Liner

After the pool is drained completely, remove the in-ground pool liner following the manufacturers instructions again. Keep all the liner clips together in a basket or bag since you will need them when putting the liner back.  

Step 3: Scrub the Liner 

Spread the liner on a flat clean surface, such as the garage floor or basement after checking it for sharp or blunt objects that could puncture it, such as small stones or nails. Place smooth buckets of water made of plastic on the edges of the liner to secure it in place. Mix a solution of one part mild cleanser to two parts hot water and begin cleaning the liner using a sponge or soft brush. Do this in small sections, rinsing away the cleanser with a garden hose. Avoid scrubbing hard as you could tear the liner and do not use any harsh abrasive cleansers that will only damage the pool liner.  

Leave the solution to sit on hard stains for at least 10 minutes before scrubbing again. If they do not dissolve immediately, repeat the process again until they disappear or fade significantly. Chlorine in swimming pools chemicals prevents permanent stains, so there are not many stains that cannot be removed from a pool liner.  

Step 4: Rinse

Rinse the entire liner again with a garden hose after cleaning it to ensure any remains of cleansing chemicals are washed away.  

Step 5: Dry the liner

Dry the liner thoroughly before installing it back in the pool using a clean rag or paper towels. An alternative to this is to drain out the excess water by attaching a small submersible pool to the drain hose and placing it in the center of the pool. If you find the bottom of your pool is uneven, brush water towards the center using a soft broom.

Refill your pool after removing the submersible pump. Allow the pool filter to run for a couple of days before adding the appropriate chemicals into it and taking a dip.
