What Are the Best Practices for Hot Tub Cover Maintenance?

Your hot tub cover does more than keep debris out — it plays a major role in heat retention, energy efficiency, and overall spa cleanliness. Proper cover maintenance helps extend its lifespan and keeps your hot tub running efficiently.

Keep the Cover Clean and Dry

Regular cleaning prevents mold, mildew, and odors. Rinse the cover weekly with water to remove dust and debris. About once a month, use a mild soap or spa-approved cover cleaner to gently scrub the surface.

Avoid harsh household cleaners, as they can break down the vinyl and protective coatings.

After cleaning, allow the cover to dry fully before closing it to prevent moisture from getting trapped inside.

Use a Vinyl Protectant

Applying a UV-resistant vinyl protectant every few months helps prevent cracking, fading, and sun damage. Sun exposure is one of the biggest causes of cover deterioration, especially in warmer or sunnier climates.

Make sure the product is designed specifically for spa covers, not automotive interiors.

Don’t Let the Cover Get Waterlogged

A heavy, sagging cover usually means water has soaked into the foam core. This can happen if the vapor barrier inside breaks down.

To prevent this:

  • Keep water chemistry balanced to reduce chemical fumes

  • Open the cover fully after shocking the spa to let gases escape

  • Avoid placing heavy objects on top of the cover

If the cover becomes waterlogged, replacement may be the safest option.

Handle the Cover Properly

Never drag your hot tub cover across the ground or use it as a seat or table. Rough handling can damage the stitching, hinges, and foam inserts.

Using a cover lifter reduces strain on the cover and makes opening and closing easier, which helps prevent long-term wear.

Protect It From Chemical Damage

High sanitizer levels and frequent shocking release gases that can break down the underside of the cover. After adding chemicals or shocking the water, leave the cover open for 15 to 30 minutes to allow fumes to dissipate.

This simple habit can significantly extend the life of your cover.

Inspect for Wear and Tear

Check the cover regularly for:

  • Cracks or fading in the vinyl

  • Broken straps or hinges

  • Tears in the stitching

  • Sagging or poor heat retention

Catching small issues early can prevent bigger problems later.
