Cleaning your hot tub shell is an essential part of routine maintenance that can extend the life of your spa, improve water quality, and ensure your hot tub stays looking great. Over time, the hot tub shell can accumulate oils, dirt, grime, and even minerals from the water. Regular cleaning will not only enhance the appearance of your hot tub but also improve your overall hot tub experience. Here’s a step-by-step guide on how to properly clean your hot tub shell for longevity.
Why Clean the Hot Tub Shell?
The hot tub shell is the main body of the tub, and it’s exposed to constant water and use. If not properly cleaned, buildup of oils, dirt, and other contaminants can affect water quality, cause staining, and even damage the material over time. Regular cleaning can:
- Prevent stains and discoloration: Bacteria, oils, and minerals can leave stains on your hot tub shell, which can be difficult to remove if left untreated.
- Protect the surface: Keeping the shell clean can prevent damage to the material (acrylic, fiberglass, etc.) and maintain its shine.
- Improve water quality: A clean shell helps to maintain balanced water chemistry, which reduces the need for excessive chemicals.
How to Clean Your Hot Tub Shell: A Step-by-Step Guide
1. Drain the Hot Tub
Before you start cleaning the shell, you’ll need to drain the hot tub to ensure that you have full access to the surface. Follow these steps:
- Turn off the power to the hot tub for safety.
- Drain the water from the tub using the drain valve or a submersible pump.
- Allow the hot tub to sit empty for a few hours to ensure all water has drained.
2. Clean the Filter
While your hot tub is drained, it’s a good time to clean the filter. A clean filter ensures proper water circulation and helps prevent buildup on the shell. Here’s how:
- Remove the filter from the tub.
- Use a hose to rinse off the filter, removing any dirt or debris.
- Soak the filter in a filter-cleaning solution (following the manufacturer’s instructions) to break down oils and residue.
- Allow the filter to dry completely before reinserting it.
3. Clean the Hot Tub Shell with the Right Cleaner
The next step is to clean the shell itself. Depending on the type of material, you’ll want to use a cleaner that’s appropriate for your hot tub’s surface.
- Acrylic Shell: For acrylic hot tubs, use a non-abrasive, pH-balanced cleaner. Avoid using harsh chemicals that can damage the surface. You can find cleaners specifically designed for hot tub shells at most pool and spa supply stores.
- Fiberglass Shell: For fiberglass hot tubs, a mild detergent or vinegar and water mixture can be effective. Be sure to use a non-abrasive cleaner to avoid scratching the surface.
- Steps for Cleaning:
- Apply the cleaner to a soft, clean cloth or sponge. Avoid using abrasive pads that could scratch the surface.
- Gently scrub the shell in circular motions, focusing on areas with visible grime or stains.
- Pay extra attention to the corners, seams, and waterline, where buildup tends to accumulate.
- Use a soft brush to scrub the jets and around the edges of the tub, as these areas can also trap dirt.
4. Remove Stubborn Stains
If you notice stubborn stains on your hot tub shell, you may need a more targeted approach:
- For Mineral Deposits: Use a vinegar solution (1 part vinegar to 3 parts water) to remove mineral buildup, such as calcium. Apply the solution to a cloth and gently scrub the stained area.
- For Oil Buildup: Use a specialized hot tub cleaner designed to remove oils and lotions that may accumulate around the waterline. These products help break down the oils and prevent them from hardening into stains.
5. Rinse the Shell Thoroughly
After scrubbing the shell, it’s important to rinse away any cleaner, residue, or dirt to prevent it from contaminating the water once refilled. Use a clean, damp cloth to wipe down the entire surface of the shell.
If necessary, you can also use a garden hose to rinse off the entire shell.
6. Dry the Shell
Once the hot tub shell is clean and rinsed, use a soft towel or microfiber cloth to dry the surface. Drying the shell helps prevent water spots and keeps the surface looking shiny.
7. Refill the Hot Tub
After cleaning and drying, it’s time to refill the hot tub. Make sure the water is properly balanced before turning on the power.
- Check the water chemistry: Test the pH, alkalinity, and sanitizer levels to ensure they are within the ideal range (pH 7.4-7.6, alkalinity 80-120 ppm, sanitizer levels per manufacturer instructions).
- Start the filtration system: Turn the power back on and allow the filtration system to run for a few hours to ensure proper water circulation.
Preventive Maintenance Tips for Keeping Your Hot Tub Shell Clean
To maintain the cleanliness of your hot tub shell and prevent buildup between cleanings, consider these tips:
- Regularly check the waterline: Keep an eye on the waterline for signs of buildup and clean it promptly to prevent stains.
- Use a cover: Always use a hot tub cover when the tub is not in use to keep out debris and minimize contaminants in the water.
- Shower before use: Encourage bathers to shower before entering the hot tub to minimize oils, lotions, and dirt entering the water.
- Use the right chemicals: Ensure your water chemistry is properly balanced, as an imbalance can lead to stains and other issues on the shell.
- Clean the tub every 3-4 months: Deep clean your hot tub shell every 3-4 months, depending on how often you use the spa. Regular cleaning will keep the shell in excellent condition and extend its lifespan.
Conclusion
Cleaning your hot tub shell is a crucial part of hot tub maintenance. By following the steps outlined above, you can prevent stains, protect the surface, and ensure that your hot tub remains in top condition for years to come. Regular maintenance, such as cleaning the shell, checking the filters, and balancing the water, will keep your hot tub sparkling clean, providing you with a relaxing and enjoyable experience each time you soak.
