Hi Regina, Thank you for your question! To remove the mildew spots from your cover I would recommend removing your cover to a safe dry place and using a little Spa System Flush on a damp rag to spot clean. After your cover has had some time to dry out, apply 303 Protectant all over. http://www.spadepot.com/shop/Spa-System-Flush-16-oz-P436C57.aspx http://www.spadepot.com/shop/303-Protectant-16-oz-P758C57.aspx Also, if your hot tub is not going to be in use for long periods of time I would recommend either draining it, or continuing to maintain your spa water weekly as well as removing the cover every so often to allow it some relief from the moisture. This will help prevent mildew in the future. Please let me know if you have any further questions! Thanks, Bonni The Spa Depot

Just opened the hot tub cover after 4 month, now I have mildew spots all over. How can I clean it ? Thank you Regina

Hi Diane, Great question! Typically a slime feeling on the underside of your hot tub cover would be the result of an imbalance in the water. I would recommend a couple of things. If your filter is over a year old it should be replaced, if not I suggest a thorough cleaning. I would also recommend draining and refilling your tub if your water has been in the spa for longer than 4 months. You will also want to thoroughly clean your cover with a non abrasive cleaner such as CleanAll Spray in order to remove the current film: http://www.spadepot.com/shop/CleanAll-Spa-Surface-Cleaner-P765C57.aspx Please feel free to give us a call if this problem persists, we are happy to help!

I purchased a new cover for my hot tub and we have been using it for about one month. Today we went to use the hot tub; the underside of the cover has a slime feeling. The test strips show the water levels are good. Do you have any ideas? Thanks,

Hi Scott, Thank you for your comment. Any silicone based products or products containing oils are not recommended for spa cover use, as they can lead to rapid deterioration of the vinyl. 303 Protectant is safe to use because it is oil free. Please let me know if you have any additional questions. Thank you, Kaisa The Spa Depot

Hello Kaisa, I just found you and now I am a follower. Read some of Your advise on spa cover maintainence for other people. Thank You! 303 cleaner I will track some down hopefully Wal Mart. What about an Armor All protecting after the cleanings? Thanks you can email me as well as blog it.

Liked your article,but you didn''t specify what to use as a protectant to revitlilize the cover. Would a vinyl spray used on car interior work?Thanks Larry

Hi Barbara, thank you for the question. Yes, these products should help to eliminate the chlorine odor. Please let me know if there is anything else I can assist you with. Thank you, Kaisa The Spa Depot

I have a chlorine odor on underside of cover. Does the above take care of that problem?

Love your blog. You have a new follower!

Hi Paul, Thank you for your comment. If you have cleaned the inside of the cover thoroughly and still notice the mildew odor, it is likely coming from inside the foam cores. This happens when moisture has penetrated the plastic and starts to grow bacteria and mildew. If your cover is in overall good condition, a way to reduce the odor is to make a small slice into the plastic around the foam and allow any trapped water to drain. Once it is thoroughly drained, patch the slice with clear packing tape, then go around and tape up any areas where water might be able to penetrate into the foam. If the cover is in bad shape, it may be worth replacing. I would recommend getting a double wrapped core on your next cover. Adding the additional water barrier really helps with longevity, odor and energy savings. Please let me know if you have any additional questions! Thank you, Kaisa The Spa Depot

Hi Karisa, I''ve got the same problem as Mark. I just cleaned the cover this weekend and did all the recomended steps but the cover still has a strong mildew smell. The foam is not water logged but it is covered by plastic wrap which I did not remove because I didn''t think I''d get it back on right. But the smell is clearly coming from the cover material so do I just live with it or should I replace the thing or do I have another option. Any advise would be helpful. Thanks

Hey Thanks for the post Any recommanded product please? This will help me a lot to make my Cover as a new one Thanks Best regards Patrick

Hello Mark, thank you for your comment. Is the hot tub cover water-logged? You can tell if you unzip the vinyl and feel or see water trapped in the plastic wrapping around the foam. A water logged hot tub cover is usually very heavy. If this is the case, water is becoming stagnant inside the plastic wrap and causing the odor. Generally the cover should not make contact with the water. Thank you, Kaisa The Spa Depot

Mark

I can''t seem to get that "funky" odor from my hot tub cover. I scrubbed it inside and out with bleach and water, let it dry, put Styrofoam back and I think it is still the cause of a foul smell in the water. And, should underside of cover make contact with the water? Thank you, Mark

Mark Walsh

Hi Randy and Donna, The build up is caused by improperly balanced, or improperly treated spa water. The two most important things in your sanitizing system are the Cleanwater Blue itself, and the Oxy Spa shock. Make sure you add the proper amount of Cleanwater Blue per the directions, and be sure to use two tablespoons of shock after each use. You do need to shock the tub at least once a week even if you do not use it. Additionally, 303 Protectant not only works great for the outside of your cover, it helps prevent build up on the underside of the cover: http://www.spadepot.com/shop/303-Protectant-16-oz-P758C149.aspx Thank you, Mark The Spa Depot

Randy and Donna Dresback

We have a slimey scum build up on the inside of our spa cover, which was brand new in May 2013, and use the Clearwater Blue system from SpaDepot to maintain our spa water. What is this yucky deposit and how may we prevent it??

Kaisa Williams

Hi Luigi, Great question. Yes, you can remove most stains from the cover underside. To do so, wet stained area with Spa System Flush and let soak for 4 hours or overnight, then wipe with a rag. This will remove 99% of stains without harming the vinyl like chlorine will. Please let me know if you have any other questions. I am happy to help! Thanks, Kaisa The Spa Depot

Luigi Antonio

Can you remove stains from the bottom part of the cover? If yes, what products can i use ?

Kaisa

Hi Tony, Thank you for your comment! A deteriorated ThermoFloat Blanket is indicative of imbalanced water chemistry. Most commonly this is caused by pH that is too low, but could also be due to excessive ozone, alkalinity imbalance or too much sanitizer (over chlorination/brominating). Your cover could suffer the same fate over time. If you would like, we can help you figure out what’s awry. Please feel free to give us a call (800) 823-3638 and ask for Mark in Technical Support. Thank you, Kaisa The Spa Depot

Tony

Helpful article. The only disagreement I have is with using the ThermoFloat blanket. The hot tub chemicals cause the ThermoFloat blanket to deteriorate causing little bits of plastic to flake off. Some of these floating plastic bits clogged up my flow valve and cost me a bit to have it replaced.

Kaisa

Hi Bill, Great question! Re-stitching will require an industrial sewing machine with heavy duty triple-ply polyester thread. The vinyl jacket is removable via zippers in the fold area. So, you should be able to bring the jacket in to your local alterations company to be repaired with the thread type mentioned above. I hope this helps! Please let me know if you have any additional questions. Thank you, Kaisa The Spa Depot

bill Hoffman

what would you use to re sew threads that have broken loose on the flaps? Thanks
