Remove Debris And Rinse Cover With A Hose

One of the first steps in cleaning your hot tub cover is to remove any debris that might be sitting on the surface. This can include leaves, dirt, and even small insects.

To do this effectively, you’ll want to use a soft brush or cloth to gently sweep away any loose particles.

After removing all visible debris from your spa cover, it’s time for a quick rinse. Using a garden hose with a spray nozzle will provide efficient results without causing potential harm from high-pressure water systems such as power washers.

Begin by wetting down the entire cover from top to bottom – this helps loosen up any stubborn dirt that may have become stuck over time.

Use A Mild Soap And Water Solution To Clean The Cover

When it comes to cleaning your hot tub cover, using a mild soap and water solution is essential. To create this solution, mix a small amount of non-foaming cleaner or pH neutral cleanser with warm water.

Then, dip a soft-bristled brush into the solution and gently scrub the cover in circular motions.

When finished, rinse the cover thoroughly with clean water from a garden hose. Avoid using high-pressure nozzles as they may damage the vinyl material of your hot tub cover.

Once you’re done rinsing, wipe down the surface of your hot tub cover with a clean towel and let it dry completely before putting it back on top of your spa.

Rinse Cover Thoroughly With Water

Once you have finished cleaning your hot tub cover with a mild soap and water solution, it is essential to rinse off any remaining soap or grime thoroughly. Use a garden hose to spray the cover from top to bottom, ensuring that all areas are covered, especially around the seams and edges where dirt can accumulate.

It is best to use cool or lukewarm water since hot water can cause damage to the vinyl material of the cover over time.

It’s important not just to give your hot tub cover a quick once-over when rinsing but instead take your time and ensure every inch is clean before moving on to drying it.

If you’re using a hose outdoors in direct sunlight, be mindful of how long you leave it out as overheating may also cause damage.

Allow The Cover To Dry Completely

After cleaning your hot tub cover, it’s crucial to let it dry completely before using it again. Letting moisture linger on the cover can lead to mold growth and cause unpleasant odors.

To ensure that your spa cover dries properly, remove any excess water with a towel or cloth after rinsing it off. Then, prop the cover open in an upright position so that air can circulate inside and out.

If you live in a humid climate or have recently experienced rainfall, consider leaving the cover open for an extended period to allow for extra drying time. Additionally, avoid folding or closing the cover until you are certain that every inch is dry to prevent trapping moisture inside.

Tips For Maintaining A Clean Hot Tub Cover

To keep your hot tub cover looking its best, it’s essential to regularly clean and condition it using a non-foaming cleaner or a pH neutral detergent. Additionally, store the cover properly when not in use and avoid using harsh chemicals or abrasive materials that can damage the vinyl material.

Regularly Clean And Condition The Cover

Taking care of your hot tub cover by regularly cleaning and conditioning it will not only keep it looking great but also extend the lifespan of the cover. To start, make sure you are using a non-foaming cleaner or a gentle cleanser that is pH neutral to avoid damaging the vinyl material of the cover.

Once you have cleaned your cover thoroughly, be sure to condition it with a waterproofing solution that will help repel water and prevent mold growth. Using vinegar or baking soda solutions can also help eliminate mildew from the surface of your hot tub cover.

Store The Cover Properly When Not In Use

After cleaning and drying your hot tub cover, it’s essential to store it properly when you’re not using it. This will help prevent damage caused by weather elements or pests such as rodents.

The best way to store the cover is to place it in a dry and cool location away from direct sunlight.

You can use a protective bag or cover for added protection against moisture and dust accumulation. Additionally, make sure you don’t fold the cover too tightly or stack heavy objects on top of it as this may cause permanent creases that could affect its performance over time.

Avoid Using Harsh Chemicals Or Abrasive Materials

When it comes to cleaning your hot tub cover, it’s important to be mindful of the products you’re using. Harsh chemicals or abrasive materials can damage the vinyl or insulation of the cover, shortening its lifespan and compromising its effectiveness.

Instead, opt for gentle cleansers that are specifically designed for hot tub covers.

Another alternative is to create a natural cleaning solution by mixing water and vinegar in equal parts or making a paste with baking soda and water. Use circular motions with a soft-bristled brush when applying any solution to avoid damaging the surface of your cover.


Cleaning your hot tub cover is an important part of maintaining your spa and ensuring it stays in great condition for years to come. To clean your hot tub cover, simply remove any debris and rinse the cover with a garden hose.

Then use a soft-bristled brush and mild soap solution to gently scrub away any dirt or grime.

To maintain a clean hot tub cover, be sure to regularly clean and condition it with gentle products designed specifically for vinyl covers. Store the cover properly when not in use, avoiding harsh chemicals or abrasive materials that can damage its surface.
