- Clean your hot tub cover when you drain and refill your spa.
Use simple soap and water or cover cleaner to keep the cover free from dirt and stains. It is important to not only clean the outside, but clean the inside as well. It is easiest to remove the cover from the spa, stand it on end then wash and rinse away from the tub.
- At least once per year, unzip the cover at the seam and pull the foam out, rotate the foam so the top is now on the bottom and the bottom is on the top.
This will help to keep the foam inside from warping under the weight of rain or snow and will help avoid low spots and puddles. At this time you can check for mold growth which can cause a smell. Mold is easily cleaned using the same method as noted above.
- Use a cover conditioner on the cover yearly after you have cleaned it with soap and water.
This will help keep the vinyl outer cover supple and will help to weatherproof the stitching, etc. A good liquid car wax will work as well, be sure to let it dry and buff it to a shine.
- Be sure to maintain a good chemical balance in your spa.
It is healthy not only for you, but for your hot tub cover as well, always use an insulating blanket on the surface of the water, this will keep the water warmer and insulate the cover from aggressive and damaging vapors.
- NEVER shock your tub with a hardcover on.
This will not allow the bacteria and chloramines to oxidize properly into the air and it could cause damaging vapors to attack the underside of your spa cover.
Utilizing these hints will extend the life of your hot tub cover and keep it looking better longer.
