How to extend the life of your Spa Cover

There are a number of things you can do to prolong the life of your Spa Cover and ensure that it performs at its best for many years. 

Generally speaking, a Spa Cover requires very little maintenance. Technically here are no moving parts and the materials used are quite hardy. However your Spa Cover is possibly out in the elements, working for you 24/7 and probably deserves a little TLC.

Here is a list of things you might consider:

  •   Using a Vinyl Protectant
  •   Cleaning your Spa Cover
  • ​  Using a Lifter
  • ​  Protecting the Zips
  •   Draining the Inserts / Storage / Water Run-off
  • ​  Protecting the Underside Material
  •   Water Balance & Ozone
  •   Stitching Issues


Perhaps the single biggest threat to your Spa Cover's longevity ( with the possible exception of the over-weight kid next door jumping on it ) is the sun.

UV degradation is always an issue for any product exposed to the sun and spa cover vinyl is no exception. Our covers are manufactured using a high grade marine vinyl but eventually it will succumb to the sun. Applying a vinyl protectant, such as 303 or Armour All, will prolong the life of the vinyl if used correctly. It's like putting on sun tan cream.


As a general rule, the cleaner you keep your spa cover, then the longer it will last.  If your spa cover is exposed to the elements, then dirty vinyl will allow the UV rays more traction and hasten degradation.

There are several cleaning products available that are labelled specifically for spa covers. They are typically a generic cleaning formula with different labels designed to attract specific users.

Unless your cover has years of ingrained dirt to be removed, then I would suggest just using dish-washing liquid, lukewarm water and a cloth ( or very soft bristle brush ) to gently wash the surface of the cover. If you do this once a month ( or depending on how quickly it gathers dirt ) it should suffice. There is no need to spend money on expensive cleaners. Dish washing liquid or saddle soap is good enough.


If you are suffering from a bad back or simply find it difficult maneuvering your spa cover on and off the spa, then a spa cover lifter may be the answer.

A Lifter will only work on a Portable Spa and there are clearance requirements. Our Lifters do not bolt onto the wooden spa sides as this tends to damage the wood and eventually the Lifter won't work anymore. Instead we promote the Uni-Lifter with a base plate that slides under the spa. This provides far greater strength and stability.

Perhaps I'm a lousy salesman but my approach to Lifters is a little bit like a good Doctor's approach to antibiotics - only use as a last resort. I prefer to look at the way a cover is used and then advise handling options to make it more manageable. If a Lifter is clearly the best option then so be it but often it's just a case of altering a handling technique.

The video below gives some insight into how the Uni-Lifter works.


Your spa cover has zips. The Manufacturer needs to fit the reinforced Polystyrene inlays into the cover and the best way to do that is by using zips. This also means that at any stage an inlay can be replaced by simply opening the zip.

After several winters, a spa cover that is exposed to the elements may have moss begin to grow in the zip start area ( The exposed section of zip at the centre hinge ). A quick squirt of silicon spray ( eg. WD40 ) once or twice a year, will solve that problem.

If moss or salt is allowed to build up on the zip start area, eventually it will seize the zip completely. There may not be of any consequence, it certainly won't affect the cover's performance but if you do wish to replace foam inlays, then the zip needs to be functioning.


Your spa cover is designed to cope with water. It sits over a large body of water in the spa and may also be exposed to rain water. The Marine Vinyl will survive wet conditions and the cover's polypropylene underside will endure the spa water. Yet if water starts to pool on the top or permeate the foam inlays, it can be very destructive.

Never allow water to pool on top of your spa cover. The inlays are tapered to encourage water run-off but if for any reason water does become trapped on top of the cover, then unzip your cover, remove the foam, flip it over and refit the inlay. This should solve the problem. If for any reason it doesn't, then get in touch with us or any responsible Supplier.

Your spa cover underside will have one or more drainage holes in it. This is to allow water from condensation to escape from the cover. Your spa cover is not completely waterproof. Some water will pass through the cover from condensation or rain and will do no harm as long as it drains away and doesn't become trapped there. 

When storing your cover off the spa, it's not a bad idea to stand it zip-side-down to increase the water drainage. If you can feel a lot of water inside the cover, then you could even open the zips but I wouldn't recommend doing that unless absolutely necessary.


This is a simple thing. When the spa cover is off the spa, store it out of the sun, either in the shade or cover it with a protective blanket. The polypropylene underside material can cope well with heat, chemicals and moisture from the spa itself but it is not UV stable. Don't leave the spa cover open on top of the spa for extended periods in the sun.


Poor water balance will not directly affect the cover but if the spa water becomes putrid, then the cover will exacerbate the problem by trapping any unpleasant odours created therein.

Ozone is a very effective sanitizing system. A small percentage of spas are fitted with an Ozonator to produce Ozone to assist with controlling microorganisms in the water. Unfortunately the older Ozone systems were incredibly hard on spa covers, causing the underside to perish prematurely. If you fold open your cover and it gives the appearance of its insides dropping out ( stitching disintegrated, plastic exposed and soggy foam hanging out ), then 100% your cover has been mauled by Ozone.

If this occurs ( generally after 3 - 5 years ), then you either resign yourself to replacing the cover every few years or turn off the Ozonator.


Any stitching problems that show up in the first 2 years are fully covered under our warranty. After that period, there is a nominal charge to resew any areas of the cover where stitching has come apart. It is highly unlikely that stitching will be a problem unless the cover is treated roughly. In most instances, minor stitching issues have very little effect on the longevity of the cover. A spa cover is not water-proof. If stitching perishes around the zip area, then it's important to contact us or your Supplier.

If you have any questions or require repairs to an existing spa cover, then contact us and we can advise and/or provide direct support.
