Hey, no offense, however your Swim Spa Cover smells bad. Maybe you’ve gotten used to it?
Don’t worry, it happens to all spa owners at some time or another; water is one of nature’s most erosive substances. Moisture leaks in and ends up being trapped between the outer vinyl shell and the cling wrap foam cores. The warm, damp environment is ideal for mold and mildew and other forms of foul-smelling stuff.
If moisture has actually penetrated further into the plastic wrapped foam core, the cover ends up being waterlogged, which can rapidly grow all sorts of dark and stinky slime, but also make the cover truly difficult to get rid of, and not as efficient at keeping the heat in the spa. Time for a better kind of Swim Spa Cover

Smelly Swim Spa Cover?!?
• Broken or damaged. Broken foam cores, ripped or used areas, torn joints. A Swim Spa Cover that loses it’s arched roofing system line, to keep water draining pipes off properly, will eventually start to puddle water, which is most likely time to buy a brand-new Swim Spa Cover! A Swim Spa Cover with threadbare spots in the vinyl is also problem, and although you can stave off the inescapable with a duct tape repair work, the water will win, ultimately.
• Not Removed Regularly. Remove your Swim Spa Cover weekly for 2 hours of airing out. A much better Swim Spa Cover can withstand longer durations, but it’s a great practice to eliminate the cover and let it get some air on a weekly basis. If you can easily open the zipper to allow moisture to get away do so, however do not remove vulnerable foam panels unless absolutely essential.

Actually, this is just hogwash The problem is the foam itself. It would be great if it were put into use in a totally dry setting. Unfortunately, swim spas by their very nature are filled with warm water. Warm water creates steam and steam rises up and gets into the cracks and crevises in the foam until it gets so heavy you can’t lift it anymore. The only way to avoid it is to never put it on the swim spa.
• Poorly Made. It’s easy to make a Swim Spa Cover with tape and staples, however it will not stop moisture very well. Even the best foam filled Lightweight Swim Spa Covers with vacuum-wrapped and heat bonded joint are not going to keep the intense moisture from your spa from reaching the foam core. The only real service is a Swim Spa Cover uses air to insulate rather than foam.
• Bad Spa Water. If the spa water is not preserved regularly with sanitizer and filtering, or is not surprised frequently enough, bacteria and algae can take advantage of a hospitable environment to grow. Low pH, high chlorine or high ozone levels can likewise degrade the underside of your Swim Spa Cover cover. Since the cover is so near to the spa, it takes in the chemistry of the spa. Tidy, clear and hygienic water is the best environment to prevent foul-smelling spa covers. (Sorry but this is just BS) The fact is the spaces in the foam are almost laboratory conditions for growing mold and mildew. Your spa chemistry is not going to stop that.
• Not Cleaned/ Conditioned. For outdoor Lightweight Swim Spa Covers, unless your back deck is covered or your spa remains in a gazebo, you have sun, rain, pollen, dust, contamination, and animals to contend with. If you have a partial roofing system, that can be worse than no roofing system at all, if an overhanging eave drains water onto the Swim Spa Cover Tidy and condition a spa cover 2-4 times annually, so that it constantly looks great, and is protected from the elements. Again, this actually isn’t really going to stop the mold and mildew from growing inside a foam cover But it will assist your spa dealership pay their expenses. If this were actually true a Swim Spa Cover inside would never get smelly and that just isn’t true.
