How to Clean and Protect Hot Tub Surfaces (Easy Steps for Maintenance)

Hot tubs are a perfect way to relax and unwind after a long day. However, maintaining them requires regular care to keep the surfaces looking clean and protected. Whether you have an acrylic, fiberglass, or wood-paneled hot tub, the surfaces can accumulate dirt, grime, and chemical build-up over time. Here’s how you can clean and protect your hot tub surfaces to ensure it remains inviting for years to come.

Why Cleaning and Protecting Your Hot Tub Surfaces is Important

Hot tub surfaces are exposed to oils, lotions, body sweat, and harsh chemicals, all of which can affect the finish and functionality. Regular cleaning and protection not only help maintain the aesthetic appeal but also prevent long-term damage, reduce the need for repairs, and prolong the life of your hot tub.

Without proper maintenance, you might face issues such as:

Discoloration: Over time, chemical build-up can stain the surface.
Cracks and damage: Dirt and grime can cause the material to weaken.
Mold and mildew: The warm environment can lead to the growth of mold and mildew if not cleaned regularly.

By following a routine cleaning and protection process, you’ll ensure that your hot tub stays in top shape for many years.

Step 1: Drain the Hot Tub

Before cleaning your hot tub, always drain the water. This ensures you can clean all surfaces thoroughly without worrying about water getting in the way.

Turn off the power to avoid accidents.
Locate the drainage valve and let the water drain out completely.
Remove the filters and clean them separately while the tub is empty.

Make sure to let the hot tub rest for about 10-15 minutes to ensure all water has fully drained before proceeding.

Step 2: Clean the Shell Surface

The shell is the main surface that needs cleaning, especially around the edges, where oils and other residues build up.

Use a non-abrasive cleaner: Harsh chemicals or abrasive scrubbers can scratch the surface. Opt for a cleaner designed specifically for hot tubs.
Soft cloth or sponge: Use a soft cloth or sponge to wipe down the surface. Avoid using rough materials that could damage the finish.
Spot clean stubborn stains: For tough stains, use a gentle scrub brush or a hot tub-specific cleaning solution.

For stubborn stains, a mixture of white vinegar and water can also work as a natural alternative. Be sure to spot test any homemade cleaning solution to avoid damage.

Step 3: Clean the Jets and Plumbing

The jets and plumbing in your hot tub are essential for proper circulation and water flow. Over time, mineral deposits and oils can clog the jets.

Use a jet cleaner: There are specialized jet cleaners that you can run through the system to break down and remove the build-up.
Flush the system: After using the jet cleaner, run the hot tub’s system without water to flush out the cleaner and any remaining residue.

It’s recommended to flush the system at least once every 3–6 months to maintain the best water flow and avoid clogging.

Step 4: Clean and Replace the Filters

Hot tub filters are essential for trapping debris, oils, and other contaminants from the water. It’s important to clean and replace them regularly.

Rinse the filters: Use a garden hose to spray off any dirt or debris from the filters. Be sure to get into the folds where dirt often accumulates.
Soak the filters: For deeper cleaning, soak the filters in a filter-cleaning solution for a few hours.
Replace the filters: Depending on the usage, replace your filters every 12–18 months to ensure the best filtration.

Regularly cleaning and replacing filters helps to maintain water quality and keeps the hot tub working efficiently. Be sure to follow the manufacturer’s instructions for filter maintenance.

Step 5: Clean the Hot Tub Cover

Don’t forget about your hot tub’s cover! The cover protects the water from debris, but it can also accumulate dirt and grime.

Clean with mild soap and water: Use a mild soap solution and a soft cloth to clean the cover. Avoid harsh chemicals that could damage the material.
Check for damage: Inspect the cover for any signs of wear and tear. A damaged cover can lead to water temperature issues and increased debris in the hot tub.
Protect the cover: Apply a UV protectant spray to the cover to protect it from sun damage and fading.

Step 6: Apply a Surface Protectant

After cleaning the hot tub, consider applying a surface protectant to keep the surfaces looking new and prevent future build-up.

Use a protectant designed for hot tubs: Look for products that are designed to add a protective layer without damaging the surface. These products often create a barrier that repels dirt and oils.
Apply sparingly: Follow the manufacturer’s instructions and apply a thin, even coat to the surface.
Buff the surface: After applying the protectant, use a soft cloth to buff the surface to a shine.

This extra step adds a protective barrier that prevents dirt and chemical build-up, making it easier to clean the next time.

Step 7: Refill the Hot Tub and Check the Water Chemistry

After cleaning and protecting all surfaces, it’s time to refill the hot tub with fresh water.

Check the water balance: Test the pH, alkalinity, and sanitizer levels to ensure the water is properly balanced. This is essential for preventing damage to the surfaces and ensuring a safe soak.
Add chemicals as needed: Use the appropriate chemicals to adjust the water’s pH and sanitizer levels.

Maintaining proper water chemistry is essential for preventing scale build-up, which can affect the surfaces of the tub.

Step 8: Keep Your Hot Tub Clean Between Deep Cleanings

While regular deep cleaning is essential, there are ways to maintain cleanliness between those sessions.

Wipe down surfaces after use: Use a microfiber cloth to wipe down the surfaces after each soak. This removes any body oils and prevents them from building up.
Use a hot tub cover daily: Always use the cover when the tub is not in use to prevent debris from falling in.
Clean the filter: Rinse the filter every month to keep it working efficiently.

By keeping up with these small steps, you’ll reduce the frequency of deep cleanings and ensure your hot tub stays in great condition.

How Often Should You Clean and Protect Your Hot Tub Surfaces?

It’s important to regularly clean and protect your hot tub to keep it in great shape.

Monthly maintenance: Clean the surface, filter, and jets every month to prevent build-up.
Quarterly deep clean: Perform a deep cleaning every three months by draining the water and thoroughly cleaning the hot tub.
Annual check-up: Inspect the cover, surface, and filters for damage at least once a year.

By sticking to a maintenance schedule, you’ll ensure that your hot tub remains clean and ready for use whenever you need it.

Tips for Maintaining Your Hot Tub Surfaces

Regularly wipe down surfaces: After each use, take a moment to wipe down the surfaces to remove oils and dirt.
Use a hot tub cover: Always keep the cover on when the tub is not in use to protect it from debris and sun damage.
Avoid harsh chemicals: Stick to products designed for hot tubs to avoid damaging the surfaces or the water balance.
Use a water clarifier: Add a water clarifier once a month to keep the water clear and prevent chemical build-up.
