Try Using Natural Cleaners

How To Remove Stains From A Vinyl Pool Liner

If youre not one for harsh chemicals, there are plenty of natural and organic options for removing stubborn stains on your pool liner. White vinegar or organic dish soap are great alternatives and can help you tackle most mildew and stains with less health and environmental impact. Theyre also cheaper than many of the other cleaners you can buy.

Pro tip: Be careful when using any cleaner to avoid bleaching or fading your liner. Always follow your manufacturer instructions and test new cleaning products on a small area before moving forward.

Another Cause Of The Liner Stains

It may not always be black algae or metal oxides causing the stains. Dye-producing organisms may be the culprits as well. These organisms will pitch camp at the backside of the pool liner. When they release the dye, it will wick through the liners fabric and form blotches.

Bottom Line

Black stains on vinyl pool liner are not the best sight. They are telling you that something somewhere is not alright. Find the problem and work on it using the methods discussed here or find yourself a self cleaning pool. If you do it right, you should not have any black stain problems and will be able to keep your pool clean. Always make sure you know the cause of the stains before trying to remove them and follow proper pool care suggestions to maintain your new pool or newly renovated pool.

Testing The Pool Wateris It Metal Staining Or Algae

Before taking any action to undergo treatment for metal stains, you need to be certain of its metal staining. Green or black stains might indicate metal stains, but they may also occur due to green or black algae. Do the vitamin C test by using ascorbic acid to determine whether its metal staining or not:

  • Hold a vitamin C tablet against a potion of the stain for about 30 seconds.
  • If the stain vanishes or lightens, then it is a metal stain and not algae.

    How To Identify Pool Stains

    How to Remove Stains from a Pool Liner

    Pool stain removal starts with identifying the types of stains youre dealing with. Most pool stains fall into 3 main categories:

    • Organic pool stains
    • Caused by everything from leaves, dirt, bugs, and berries, to algae, worms, and bodily oils
  • Metal pool stains
  • Copper, iron, and manganese can be introduced by pool equipment, corroded plumbing, or water sources
  • Rust pool stains
  • Caused by corroded pool fixtures and misplaced metal objects left in the pool
  • There are also waterline stains and mineral stains . Well explain how to remove these later in the post as well.

    The color of a stain indicates what type of stain it is. And by recognizing a few color combinations, you can diagnose your pool stains faster.

    To identify the type of pool stain youre dealing with, match its color to one of the descriptions below:

    Green or green-brown pool stains

    Usually caused by decomposed leaves, twigs, algae, or other plant life. Sometimes caused by decomposed bugs or critters.

    Red or blue stains

    Bright red or blue stains are usually the leftover remains of decomposed berries

    Blue-Green or Teal stains

    This distinct color combination is produced by copper.

    Dark red or Brown stains

    Dark wine colored splotches are the result of iron.

    Black or purple-ish stains

    This coloration is only produced by manganese

    Prevent Vinyl Pool Stains

    Preventing pool liner stains requires vigilance! Watching the pool like a hawk for foreign objects, keeping it clean and keeping it balanced are the main ways to keep stains off of your pool liner, with special attention to how you add pool chemicals.

    Foreign Objects: When my kids were young, they knew what things they could not bring in the pool. This list included hair clips, bobby pins and soccer cleats. Also not allowed were Barbie dolls and plastic swords, or any non-pool toy that not only could stain a liner but puncture it as well. Other things Ive found include lawnmower wheels, barbecue tongs, a sunken July Fourth firework. Take it from me: Anything made of metal will rust and anything with a color can stain a pool liner.

    Keeping It Clean: Almost anything on your liner or steps long enough is going to make a stain. Leaves, berries, twigs and sticks all leach out colors but are easy to remove with high chlorine and a little brushing. Worms or dead animals are a more difficult stain to remove and may require a stain remover chemical.

    Adding Chemicals: Many vinyl staining problems occur immediately after large-scale water balance adjustments or shocking of the pool. Ive taken calls from dozens of folks, panicked at sudden stains that appeared after adding pool chemicals. To avoid this, I always add chemicals separately, at least four hours apart, and always add large doses in small increments over 24 hours time.

    Tips To Prevent Pool Liner Stains

    • Keep your pool chemistry balanced
    • Keep debris out of the pool, and dont let leaves or dirt sit on steps or pool floor
    • Use metal sequesters to keep metals from building up again if youve had problems with it in the past
    • Try using a pool cover to keep dirt and debris out
    • Brush and vacuum your pool once a week
    • Shock your pool regularly

    Ask the Pool Guy: How do I remove copper stains from my vinyl liner from copper algaecide?

    Theres no doubt that cleaning and treating organic stains is easier than tackling metal-based ones. By first ridding your pool water and filter of foreign debris, you will be able to see the stain and pinpoint where exactly it is coming from to be mindful of the area in the future. Vacuuming the surface and scrubbing the walls and pool floor will also help treat and get rid of the organic stain. During this process, it is essential to test your pool water. Investing in a test-kit that measures the level of chlorine and pH will be beneficial to minimize the appearance of stains before attempting to scrub it or use powerful shocking chemicals.

    For tough organic stains, you may have to use pool stain removers. Make sure to purchase one that can be used on your specific pool liner as they can cause more damage than good if not used properly. As always, be sure to store these chemicals properly as they can pose potential hazards to children and pets.

    How To Remove Iron Stains From Vinyl Pool Liner

    21 July, 2017


    Never use an object with shape edges or abrasive materials to clean your vinyl liner. Doing so will weaken the liner and may even puncture it.

    Proper use of chemicals and regular monitoring of your water will help reduce chemical damage, metal stains and algae growth. But you will still need to clean your vinyl pool liner on a regular basis to keep it looking its best. Regular cleaning will keep dirt to a minimum, though you may still need to do some heavy-duty cleaning once or twice a season. With the right cleaning methods, your vinyl pool liner will look good for years to come.

    Use a nylon pool brush to scrub down your entire liner on a weekly basis throughout the swimming season. A brush without any sharp edges is best, such as the deluxe wall brush available from Save on Pool Supplies. A liner is susceptible to tearing, so sharp edges can easily cause damage.

    • Proper use of chemicals and regular monitoring of your water will help reduce chemical damage, metal stains and algae growth.
    • Regular cleaning will keep dirt to a minimum, though you may still need to do some heavy-duty cleaning once or twice a season.

    Apply a mild cleanser directly to dirt on your vinyl liner, or rub it on with a soft cloth. You can use a regular vinyl cleaner like Armor All Cleaner, or you can buy a specialty cleaner like Bio-Dex Quick ‘n Thick.
