Hey, no offense, however your hot tub cover smells bad. Maybe you’ve gotten used to it?
Don’t worry, it occurs to all spa owners at some time or another; water is one of nature’s most erosive compounds. Moisture leaks in and becomes trapped between the outer vinyl shell and the cling wrap foam cores. The warm, damp environment is perfect for mold and mildew and other kinds of foul-smelling things.
If wetness has actually penetrated further into the cling wrap foam core, the cover becomes waterlogged, which can rapidly grow all sorts of dark and smelly slime, but likewise make the cover actually difficult to eliminate, and not as reliable at keeping the heat in the spa. Time for a better kind of hot tub cover

Stinky Hot Tub Cover?!?
• Broken or damaged. Cracked foam cores, ripped or used spots, torn seams. A hot tub cover that loses it’s arched roofing line, to keep water draining pipes off correctly, will ultimately start to puddle water, which is most likely time to purchase a new hot tub cover! A spa cover with threadbare spots in the vinyl is likewise problem, and although you can ward off the inescapable with a duct tape repair work, the water will win, eventually.
• Not Removed Regularly. Remove your hot tub cover weekly for 2 hours of airing out. A better cover can stand up to longer periods, however it’s an excellent practice to remove the cover and let it get some air on a weekly basis. If you can quickly open the zipper to enable wetness to leave do so, however do not get rid of fragile 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, hot tubs 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 hot tub.
• Poorly Made. It’s simple to make a hot tub cover with tape and staples, however it will not stop moisture effectively. Even the best foam filled Hot Tub Covers with vacuum-wrapped and heat bonded seam are not going to keep the extreme moisture from your spa from reaching the foam core. The only genuine solution is a hot tub cover uses air to insulate instead of foam.
• Bad Spa Water. If the spa water is not preserved regularly with sanitizer and filtering, or is not shocked typically enough, bacteria and algae can make the most of a congenial environment to grow. Low pH, high chlorine or high ozone levels can likewise weaken the underside of your hot tub cover cover. Due to the fact that the cover is so near to the spa, it takes in the chemistry of the spa. Clean, clear and sanitary water is the very best environment to prevent smelly spa covers. (Sorry but this is just BS) The reality is the spaces in the foam are nearly laboratory conditions for growing mold and mildew. Your spa chemistry is not going to stop that.
• Not Cleaned/ Conditioned. For outdoor Hot Tub 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 roof, that can be worse than no roofing at all, if an overhanging eave drains water onto the spa cover. Tidy and condition a spa cover 2-4 times per year, so that it constantly looks great, and is protected from the aspects. Again, this really isn’t going to stop the mold and mildew from growing inside a foam cover. But it will help your spa dealership pay their expenses.
