Caring For Your Vinyl Pool Liner — 20 Tips & Tricks



Your vinyl pool liner is an investment. If you want it to last and provide years of fun for your family, you have to take care of it. With that in mind, we’ve put together some handy tips and tricks to help you protect your vinyl pool liner from tears, leaks, fading, and other damage.

1. Don’t overuse or underuse chemicals.

Overusing chemicals — like bleach, pool shocks, and chlorine — can cause stains, fading, wrinkles, corrosion, and make your liner brittle. Along the same lines, not using chemicals to keep your water clean and balanced can also cause issues, including algae growth, which can stain your liner or lead to fading. 

2. Keep the water chemistry balanced.

Overall, it’s best to test your water chemistry frequently (at least weekly — but more often if you’re in the pool on a regular basis) and make sure levels are appropriate. Ideal levels are as follows:

  • Chlorine: 1.0-2.0 ppm
  • pH: 7.2-7.8
  • Calcium Hardness: 180-220 ppm
  • Alkalinity: 80-120 ppm
  • Dissolved solids: below 5000 ppm
  • Cyanuric Acid: 40-80 ppm
  • Chloramine: Below 0.4 ppm

3. Always read the directions.

When using chemicals, be sure to follow all directions and safety guidelines noted by the manufacturer of both your pool liner and the chemicals. Accidentally mixing the wrong chemicals, using the wrong amounts, or adding them at the wrong time may not only damage your liner, but can cause chemical reactions that can be dangerous to humans and pets or cause the chemicals to be ineffective.

4. Don’t cover your pool after adding chemicals…

Pool CoverYou want to wait at least 24 hours before covering your pool with a pool cover after you add chemicals. Creating a closed environment can cause chemical concentrations that can damage your liner. Be sure to test the water again before adding your cover. 

5. …but cover it other times when not in use.

Covering your pool when you’re not using it helps prevent unnecessary weathering and keeps the sun from fading your liner. It also keeps out debris and wild animals that could cause scratching and other damage.

6. Avoid floating chlorinators.

These can create uneven chlorine dispersion throughout the pool, which can cause fading or staining in specific spots on your liner when it gets too concentrated.

Pool Scrubbing Mitt7. Only use cleaning tools intended for vinyl pool liners

This almost goes without saying, but yet we need to say it. Oftentimes people use abrasive scrubbers that they have on hand for cleaning the house, like steel wool and scratcher pads, which are too rough for the liner and leave marks. Another common issue is using vacuum heads or other tools meant for cement pools, not vinyl liners. These types of tools are generally too rough and cause holes and other damage.

8. Clean your pool regularly.

Cleaning your pool consistently helps prevent staining and discoloration. If you’re cleaning and maintaining your pool regularly, you’re also likely to notice damage, leaks, and other issues before they become a major (and costly) problem. 

9. Pay special attention to the waterline and corners when cleaning

When cleaning, you want to make sure you’re cleaning especially well around the waterline and hard-to-reach corners. These are common areas for debris, oil from your skin, and scum to build up, causing staining on the liner.

10. Don’t drain your swimming pool

Gravity and water pressure are necessary to hold your vinyl pool liner in place and prevent shrinking and other issues. Thus, draining your pool can cause damage to your liner and the pool structure itself. Generally, you should only drain your pool if you’re replacing the liner or under the guidance of a swimming pool professional. Most maintenance and repair tasks can be done without draining the pool. 

11. Use caution when using sharp objects around the pool.

Be extra careful of sharp objects — such as tools, stones, sticks, and glass — around your pool. These items can easily cause rips and tears in your liner. Store your grilling accessories, power tools, and other backyard necessities when you’re done using them. You’ll also want to keep a close eye on kids to prevent them from throwing sticks, rocks, and other foreign objects into the pool. 

Water Paddle and Ball Set12. Only allow pool toys in the pool.

Opt for water-friendly pool toys, like dive sticks and floats, and leave the Barbie dolls, Legos, robots, and other toys inside. While they may seem harmless, these toys can potentially poke holes and cause damage to your liner.

13. Avoid using glass and other breakables around the pool.

Broken glass is not only a hazard for the humans wandering barefoot around your patio area, but it can also scratch and damage your pool liner. When possible, opt for plastic and other pool-friendly, reusable options to avoid accidental damage from broken glass.

14. Always wear proper swimwear in the pool.

While it may be tempting to just jump in on a hot day, be sure you and other swimmers change into proper swimming attire. Buttons, zippers, and metal clasps found on your normal clothes can potentially damage your liner. Random items, such as keys or pocket knives, left in your pocket also pose a risk to your liner if they find their way into your pool. You should also remove your shoes or opt for water shoes while swimming.

15. Remove jewelry before entering the pool.

Sharp charms on bracelets, necklaces, and earrings have the potential to damage your liner. Plus, the chemicals used in your pool can potentially cause wear and tear on your jewelry and gems. Overall, your safest bet is to take off jewelry before swimming.

16. Avoid metal/plastic hair accessories.

If you plan to pull your hair back while swimming, we recommend soft ponytail holders and scrunchies or cloth/elastic headbands. Metal hair clips, bobby pins, and other plastic hair accessories can potentially damage your liner if they accidentally fall out.

17. Beware of heat.

Candles, grills, tiki torches, and backyard campfires can cause melting, burns, and scorch marks if they accidentally get too close to your liner. 

  • Keep all heat sources a safe distance from the pool/liner. 
  • Extinguish flames before leaving the pool area. 
  • Keep candles, sparklers, and other fireworks away from the pool during celebrations like Fourth of July or birthdays.

18. Follow instructions when installing your liner.

We often see damage happen during the liner installation process. Make sure you’re following all instructions and taking care of your liner during this important step. 

  • Use caution when opening packaging to avoid accidentally slicing the liner with a knife. 
  • Clean the area around your pool before installing your new vinyl liner. Sticks and other debris could possibly puncture your liner. 
  • Make sure it’s warm enough. Your new liner should be installed when it’s 80 degrees and sunny or your liner may not work as well.
