How To Remove Stains From A Vinyl Pool Liner


There’s nothing quite like the look of a pool with a spotless vinyl liner and perfectly balanced, crystal clear water. But that idyllic moment might only happen when you first install a liner, unless you know how to remove stains from a vinyl pool liner.

Of course, cleaning your pool is a regular part of your swimming pool maintenance. But, until you know how to get rid of vinyl liner staining, you can do all the cleaning you want and your pool water and lining still won’t look its best.

The Two Main Types Vinyl Pool Liner Stains

Before you begin your liner cleaning, it helps to know what type of stain you are dealing with. Liner stains generally fall into one of two categories. Organic stains are usually a shade of brown or green and are caused by things like dirt, leaves, algae, bugs and other organic matter.

Metal can stain your pool in a variety of colours. Metal stains may be caused by pool ladders, pipes, heaters and even the pool water.

How to Clean Organic Liner Stains

  1. Get rid of any debris in the water, vacuum the pool and clean the filter.

  2. Use a soft-bristled brush to get rid of any easy-to-remove stains.

  3. Balance the pool’s water chemistry.

  4. Shock the pool.

  5. Brush the stains again after shocking the pool.

  6. For more stubborn stains, try pool liner stain remover, or a stain eraser tool, both of which should be available at your local pool supply store.

How to Clean to Clean Metal Liner Stains

  1. Check for obvious sources of the stains, like rust around the pool ladder.

  2. Get rid of any debris in the water, vacuum the pool and clean the filter.

  3. Balance the pool’s water chemistry.

  4. Use a metal test kit to confirm that metals are present in the water. And get rid of them with a metal sequestering agent.

  5. Use a metal stain remover to get rid of tough stains.

  6. You may need to change the metal parts of your pool, or even your water source, depending on what causes the stains.

If you suffer from ongoing staining, your best option may be to hire a professional pool maintenance company like Aveco to keep your pool looking great and avoid prematurely changing your vinyl pool liner.
