Using Baking Soda for Hot Tubs

Quck answer

Baking soda can be used to maintain and clean hot tubs. It helps to balance the pH levels and keep the water clean. To use baking soda for hot tubs, follow these steps:

1. Test the pH level of the water using a testing kit.

2. If the pH level is below 7.2, add baking soda to increase it. Start with 1 tablespoon per 100 gallons of water.

3. Allow the water to circulate for a few hours and then retest the pH level.

4. Repeat the process until the pH level is between 7.2 and 7.8.

5. Baking soda can also be used to clean the hot tub surfaces. Make a paste with baking soda and water, apply it to the surfaces, and scrub with a brush.

6. Rinse the surfaces thoroughly with water.

Remember to always follow the manufacturer’s instructions and consult a professional if needed.


Baking soda can be beneficial for hot tub owners as it helps maintain the proper pH level of the water. It is important for hot tubs or pools to have a pH between 7.2 and 7.8. If the water is too acidic, it can damage the heater element. Baking soda can increase the alkalinity of the water and restore the pH to the appropriate level.

Step 1

Measure 1 oz. of baking soda and sprinkle it around the hot tub. Let the water sit for two to three hours.

Step 2

Turn on the jets for approximately 20 minutes. Dip a pH test strip into the water for a few seconds. Take out the test strip and place it on a flat surface. Wait for 10 seconds.

Step 3

Compare the test strip with the guide provided in the box. This will indicate the pH level of the water. If the pH level is below 7.2, add another 1 oz. of baking soda to the water and retest it after a few hours.
