Step-by-Step Guide to Cleaning and Maintaining Your Hot Tub or Spa
1. Water Care and Chemical Balance
One of the most important aspects of hot tub maintenance is keeping the water clean and properly balanced. Proper water chemistry prevents problems such as cloudy water, skin irritation, and scale buildup. It’s essential to test the water at least once a week, especially if your hot tub is used frequently.
1.1 Test Water Chemistry
To maintain proper water chemistry, you need to test the following factors:
- pH Levels: The pH level determines how acidic or alkaline the water is. Ideally, the pH of your hot tub water should be between 7.2 and 7.8. If the pH is too high, the water becomes alkaline, which can lead to scaling and cloudy water. If it’s too low, it can cause corrosion of the spa components.
- Alkalinity: Alkalinity refers to the water’s ability to neutralize acid. It helps to stabilize the pH levels. The ideal range for alkalinity is 80–120 ppm (parts per million).
- Calcium Hardness: This measures the amount of dissolved calcium in the water. The ideal range for calcium hardness is between 150 and 250 ppm. If the calcium level is too high, it can cause scaling, while low levels can cause corrosion.
- Sanitizer Levels: Chlorine or bromine are the most common sanitizers used in hot tubs. Keep the sanitizer levels in the recommended range to kill bacteria and other contaminants. Chlorine should be kept between 3–5 ppm, while bromine levels should be between 4–6 ppm.
You can test the water using test strips or a liquid test kit. Once you’ve tested the water, adjust the chemicals as needed to bring them into the ideal ranges.
1.2 Add Chemicals
Based on the test results, you may need to add specific chemicals to maintain the balance:
- pH increaser or decreaser: Adjust the pH by adding either a pH increaser or a pH decreaser.
- Alkalinity increaser: If the alkalinity is too low, add an alkalinity increaser to bring it back into the proper range.
- Calcium hardness increaser: If the calcium hardness is too low, you can use a calcium hardness increaser.
- Sanitizers: Regularly check and add chlorine or bromine to maintain proper sanitization levels.
1.3 Shocking the Water
Shocking your hot tub means adding a large dose of oxidizing chemicals to break down organic contaminants such as body oils, sweat, and cosmetics. Shocking should be done every 1–2 weeks, or more often if the hot tub is heavily used. Use a non-chlorine shock or a chlorine-based shock, depending on the type of sanitizer used.
2. Cleaning the Hot Tub or Spa Filter
The filter plays a crucial role in maintaining the cleanliness of your hot tub or spa by trapping dirt, oils, and debris. Regularly cleaning the filter prevents it from becoming clogged and helps maintain water clarity.
2.1 Remove the Filter
Locate the filter in your hot tub. It is typically located in the skimmer area or near the pump. Remove the filter by twisting or unscrewing it, depending on your spa model.
2.2 Clean the Filter
There are two main ways to clean a hot tub filter:
- Rinsing with a Hose: Use a garden hose with a high-pressure nozzle to rinse the filter. Spray water through the filter pleats to remove dirt and debris. Make sure to clean both sides of the filter.
- Soaking in a Filter Cleaner: For more thorough cleaning, soak the filter in a filter cleaner solution. These cleaners are specially designed to remove oils, scale, and other buildup that a simple rinse may not eliminate. Soak the filter for several hours (or as recommended by the manufacturer), then rinse it thoroughly with water.
2.3 Replace the Filter
Filters should be replaced approximately every 1–2 years, depending on usage and the manufacturer’s recommendations. Over time, filters degrade and become less effective, so replacing them is essential for maintaining water quality.
3. Cleaning the Hot Tub or Spa Shell
The surface of your hot tub or spa, including the shell and tiles, needs regular cleaning to remove dirt, body oils, soap scum, and other debris. Cleaning the shell helps maintain the appearance of your spa and prevents buildup that can affect the water quality.
3.1 Wipe Down the Shell
Once a week, use a soft cloth or sponge to wipe down the interior surfaces of the hot tub. Use a spa-safe cleaner that is gentle and won’t damage the finish. Avoid harsh chemicals like bleach, which can cause discoloration.
For stubborn spots or stains, you can use a non-abrasive cleaner or baking soda. Avoid abrasive scrubbers, as they can scratch the surface of the spa.
3.2 Clean the Spa Jets
Hot tub jets can accumulate grime, minerals, and biofilm. Clean the jets monthly by using a small brush to scrub them. If your spa jets are removable, take them out and soak them in a vinegar solution to dissolve any buildup.
4. Maintaining the Hot Tub Cover
A well-maintained hot tub cover helps retain heat, keeping your spa energy-efficient and clean. It also protects the water from debris like leaves, dirt, and insects.
4.1 Clean the Cover
To clean the cover, use a mild soap solution and a soft cloth to wipe down both sides. Avoid using harsh chemicals that can damage the material. If there is a buildup of mold or mildew, use a special mold cleaner or vinegar solution.
4.2 Inspect the Cover for Damage
Check your hot tub cover regularly for signs of wear and tear. Over time, covers can become brittle or damaged from the sun and weather exposure. If the cover becomes damaged, it may need to be replaced to prevent heat loss and debris buildup.
5. Draining and Refilling the Hot Tub
Even with regular chemical maintenance, it’s essential to drain and refill your hot tub every 3–4 months to refresh the water and ensure that the chemicals are properly balanced. This helps eliminate any buildup of minerals, body oils, and other contaminants.
5.1 Draining the Water
To drain the hot tub, locate the drain valve, which is typically located near the bottom of the tub. Attach a garden hose to the valve and open it to allow the water to drain. Depending on the size of the tub, this process may take a few hours.
5.2 Refilling the Hot Tub
Once the water has been drained, refill the tub with clean water. Be sure to check the water level as it fills and stop when it reaches the appropriate level (usually just above the filter). Once full, test the water chemistry and add the necessary chemicals to bring it into balance.
6. Checking the Spa’s Equipment and Components
Regularly inspect the hot tub’s components, such as the heater, pump, and circulation system. Look for signs of damage or wear and tear that could affect performance. If you notice any issues, it may be time to call a professional for repairs.
6.1 Inspect the Heater
The heater keeps your hot tub warm and comfortable. Inspect the heater for any visible signs of corrosion or buildup, which could affect its performance.
6.2 Check the Pump and Circulation System
Ensure that the pump is running properly, and listen for any unusual noises. The circulation system should keep water moving through the filter and heater. If you notice that the water isn’t circulating properly, it may indicate a problem with the pump or plumbing.
