How to Remove and Repair Hot Tub Foam

Hot tubs come equipped with covers to prevent foreign objects such as leaves, tree branches, insects, rain and snow out of the water. Some of these objects can clog the filter or even get inside the jets. The cover is generally constructed of foam and covered in vinyl. Covers might also contain water-sealed wood to add weight, keeping them in place. If your hot tub cover has become waterlogged, you'll have to remove the foam and replace it. Letting it simply dry may only promote mold growth.

Instructions

- 1
  Take the cover off the hot tub and unzip it. Remove any wood, if applicable, and hang the vinyl inside-out to dry over a fence or clothesline.
- 2
  Put on rubber gloves and fill a bucket with bleach. Scrub the vinyl thoroughly with bleach, using the scrub brush to kill algae, bacteria and mold that may be on the vinyl. Rinse the vinyl with the garden hose and let it air-dry.
- 3
  Purchase new foam panels at a pool and spa supply store. You can typically purchase foam in 4-by-8-foot pieces.
- 4
  Measure the old foam pieces and cut the new foam to size with a utility knife. Cover the foam in polyurethane wrap and tape it shut with silicone tape. Each of these is waterproof and will keep the foam from becoming waterlogged.
- 5
  Turn the vinyl cover right-side out and put the wood back in, if so equipped. Stuff the new foam into the vinyl cover and zip the cover closed to finish repairing your hot tub cover.
