How to Clean Your Pool Liner - Tips & Suggestions
Pool liners serve the important functions of maintaining a waterproof barrier to keep water in and providing aesthetic value, with a range of liner colours and patterns available to ensure your pool always looks inviting.
Generally, swimming pool liners are made of PVC and tend to last between 5 and 20 years, so they can be pretty durable. But, to ensure your liner lasts as long as possible, it is a good idea to perform regular cleaning and maintenance. With the right cleaning products and equipment, you can easily remove stains and keep your liner spick and span. In this blog, we’ll tell you how to clean your pool liner correctly!
Before we consider how to clean your pool liner, it's a good idea to know what to be on the lookout for when it comes to good liner maintenance.
Before we explain how to clean your pool liner, it’s important to remember to not drain your pool, even if the liner is looking particularly grubby. This can cause cracking in the pool’s shell and prompt the liner itself to wrinkle or become displaced.
We recommend removing debris like leaves and other natural detritus as soon as possible – leaf nets are good to have on hand for when you notice any infiltrators. If left to decay in the water, debris will cause stains on your liner that can be tough to remove if unaddressed.
You can prevent the majority of debris from entering your pool by using a swimming pool cover.
Pool chemistry is the backbone of good pool maintenance; if you don’t pay careful attention to your water’s chemical levels, there are several things that can go wrong. Most relevant here is that improperly balanced water could cause damage or bleaching to the liner.
Incorrect pH and chlorine levels put the liner at risk of damage or staining. The cyanuric acid range should also be reviewed, as too little can cause wrinkling.
It’s also important that chemicals are always thoroughly dispersed through the water and are properly circulated, not only to ensure their efficacy but also to stop any chemicals from collecting on the bottom and corrupting or bleaching the liner.
When cleaning your liner, always make sure you use supplies that are made for the job. It’s best to use purpose-made tile liner cleaner to remove scum lines and stains, along with soft pool brushes, so you don’t cause any tears with more abrasive equipment.
Here are some simple steps you can incorporate into your routine to ensure you’re paying your vinyl liner a bit of attention on a relatively regular basis.
Often the best course of action is prevention – some stains may crop up now and again, but doing what you can to protect your liner will prevent you from having to deal with immovable dirt and grime.
Usually, covering your pool, balancing the water with the right chemicals and using a pool vacuum every so often is enough to keep everything clean and in good condition.
If your liner has come to the end of its life and is beyond the help of a good clean or quick-fix repair, it may be time to replace it. Take a look at our pool liner calculator to choose the right liner specs for your pool, including different options for colour and tile design.
Keeping your pool liner clean is straightforward with the right approach and tools. Regular maintenance, like gently scrubbing the liner with a soft pool brush, helps remove dirt and grime without causing damage. To prevent algae buildup and keep your liner looking fresh, consider using algaecides and shock treatments as part of your pool care routine.
For added protection, a durable pool cover can shield your liner from harmful UV rays, debris, and weather, helping to extend its lifespan. Investing in a reliable pool cleaner, such as a robotic model, can make routine maintenance even easier. With consistent care and the right products, you can keep your pool liner pristine and your water crystal clear for seasons to come.

It’s recommended to clean your pool liner at least once a week to avoid the accumulation of debris, algae, and discoloration. If your pool sees heavy use or has noticeable dirt or algae, more frequent cleaning might be necessary. Routine upkeep, like gently scrubbing the liner and clearing away debris, helps maintain its appearance and reduces the effort needed for more intensive cleanings.
Essential tools for cleaning a pool liner include a soft pool brush to prevent scratching or damaging the liner, a sponge or cloth for detailed cleaning, and a pool cleaner designed specifically for pool liners. When purchasing, always ensure the product is safe for use on either "all pool materials" or specifically "liners."
However, tools alone aren’t enough—here’s a step-by-step guide with recommended products:
Remove dirt and debris: Use a telescopic pole and net to skim the surface and remove any floating debris.
Vacuum the pool and clean the filter: A reliable pool cleaner can make this process quicker and more thorough, while regular filter cleaning ensures efficiency. We have a new sand filter cleaner, that would be perfect for this task.
Gently scrub the pool liner: Use a soft-bristle brush to clean stubborn dirt and stains gently, avoiding any damage to the liner.
Balance the water chemistry: Use water test strips or test tablets with a comparator to ensure the pH, chlorine, and alkalinity levels are balanced.
Shock your pool: Apply a shock treatment to eliminate bacteria and algae, keeping the water crystal clear.
With the right tools and proper care, maintaining your pool liner becomes straightforward and effective. For tough stains or if you’re unsure about performing these tasks yourself, consider reaching out to a local pool professional. If you need help locating one, feel free to contact 1st Direct Pools—we have connections across the country and can assist you in finding the right help.
No, household cleaners can contain chemicals like bleach or ammonia that can weaken the vinyl material and affect the pool’s pH balance, potentially harming swimmers. Instead, opt for a cleaner specifically designed for vinyl pool liners, as these are formulated to be safe and effective without disrupting water chemistry.
For stubborn stains caused by dirt, algae, or hard water, use a specialised pool liner cleaner. Apply the cleaner directly to the stained area and let it sit for a few minutes to break down the residue. Then, use a soft brush or sponge to gently scrub the area.
We always recommend consulting a pool professional for tough stains and maintenance. They can provide guidance on the best practices and ensure that no products or chemicals are used that might damage your liner. Pool liners can be sensitive, so it’s important to follow the correct process. Applying the same cleaning rules listed in the guide above—such as balancing water chemistry, using the appropriate tools, and avoiding harsh scrubbing—can help maintain your liner's condition while effectively removing stains.
Algae prevention starts with proper water maintenance. Keep the chlorine and pH levels within the recommended range, as algae thrive in unbalanced water. Ensure your pool filter is working efficiently and run it for the recommended hours daily to keep water circulating. Brushing the liner regularly and using an algaecide or shock treatment as part of your pool care routine can also help.
Yes, prolonged exposure to UV rays can cause your pool liner to fade, become brittle, or degrade over time. To protect it, consider using a pool cover when the pool is not in use, especially during periods of strong sunlight.
