Smelly Hot Tub Covers

Does you Hot Tub smell like mildew even though your chemicals are right?  Have you ever changed your spa water? Shocked your hot tub chemicals and still you have that moldy smell? Do you know what is causing that moldy smell that still remains no matter how you clean your hot tub?

It is not the water, it is basically the Hot Tub Covers. What you are smelling is the mildew that has grown in that foam hot tub cover. No matter what you do to the water in your hot tub that smell is going to stay and remain even if you clean the water.  If you want to prove it to yourself, then why not try this... Go out and take that old hot tub cover off your hot tub. After that, try to set it far away from the hot tub. After that, check your spa chemicals.   After a day or so go out and take a whiff of your hot tub.  So, do you smell any mildew?  Now this time put the old rigid foam hot tub cover back on the hot tub.  In a couple hours, try to repeat the smell test. The smell is back, as strong as ever.

So are you doomed to having a smelly hot tub?  What if you buy a New Foam Hot Tub Cover?  Would that be able to help get rid of that unlikely smell?  Only if you do not put water in your spa!  But that sort of defeats the purpose doesn't it. 

Want to know why does this happen? It is simply because rigid foam hot tub covers are almost perfect laboratory conditions to grow mold and mildew when you put them over a warm source of moisture.  The foam is actually pretty good insulation if you keep it dry.  Once it starts to saturate with water, the little air spaces in it that do the insulating are gone.  When that happens, and since it always does, your foam filled hot tub cover has about as much insulation as a wet piece of plywood.
So what would be the answer to this dilemma?  Get rid of that heavy foam hot tub cover and get something different.  Get something totally different than the rigid foam hot tub covers and get a SpaCap Hot Tub Cover. 

How is a SpaCap better than others?  The SpaCap does not use foam to insulate.  Instead of using foam the SpaCap uses air chambers like your storm windows do.  Layers of air. blanket your hot tub right from the water level.  Laying right on the water, the air filled hot tub cover insulates the water not the steam above the water.  Since it does not use foam, SpaCap Hot Tub Covers do not have any place for the mildew to grow.  So your hot tub chemicals stay more consistent, your water stays warm and you do not end up with a foul smell.  With Spacap you can get greatly back to enjoying your hot tub.
