Why Use Baking Soda?

Baking soda, a common household item, is an excellent choice for cleaning inflatable hot tub filters. It’s natural, safe, and effective at removing dirt and grease. Plus, it’s gentle, so it won’t damage the filter material.

Steps for Cleaning with Baking Soda

  1. Remove the Filter: Turn off your hot tub and carefully remove the filter. It’s important to ensure the tub isn’t running without its filter.
  2. Initial Rinse: Rinse the filter under running water to remove loose debris. Be gentle to avoid damaging the filter fibers.
  3. Prepare Baking Soda Solution: In a large bucket, mix a generous amount of baking soda with warm water. Stir until the baking soda is dissolved.
  4. Soak the Filter: Submerge the filter in the baking soda solution. Allow it to soak for at least 2 hours. For more thorough cleaning, you can leave it overnight.
  5. Scrub if Necessary: For tougher grime, gently scrub the filter with a soft brush after soaking.
  6. Rinse the Filter: Rinse the filter thoroughly under running water until all traces of baking soda are gone. It’s crucial to remove all residue to prevent foaming in the hot tub.
  7. Dry the Filter: Allow the filter to air dry completely. This step is important to prevent mold and mildew.
  8. Reinstall the Filter: Once dry, place the filter back in your inflatable hot tub. Make sure it’s properly fitted.
