How To Clean Your Hot Tub Jets In 2 Easy Ways

This post will show you how to clean your hot tub jets. We will show you how to remove scale buildup from the jets and give you some helpful tips about keeping your hot tub jets clean.

If you have a hot tub, you will probably want to clean it regularly. Hot tubs require cleaning because they accumulate minerals and other debris over time. This accumulation can affect your water quality, and it can also cause your jets to clog or become hard to use. Whether you have a hot tub, a swimming pool, a spa, or a whirlpool, you should learn to clean your hot tub jets.

Flush the Plumbing Lines

Don't forget to flush the plumbing lines. Not cleaning the plumbing lines will undo all your work cleaning the jets. Hot tub flush removes biofilm and bacteria left out after a complete drain. Pour an appropriate amount of biofilm remover directly into the water and run the jets for two hours. Drain the hot tub and proceed with cleaning the jets.

Clean the Jets

There are two cleaning methods: taking the jets out and soaking them overnight in vinegar and water, and filling the hot tub just enough to cover the jets, and adding dishwasher detergent.

Method 1

This method is more involved as it requires you to remove the jets one by one and put them all back after cleaning.

method 1
  1. Remove the jets and soak them in vinegar and water overnight.
  2. Scrub the internal gears with a small brush to remove all debris and minerals built up within the jet component.
  3. Put the jets back in. See to it that they're screwed tight and are not misaligned to avoid leaks.

White vinegar has been used for many years as a powerful cleaning agent for hot tubs because it dissolves buildup effectively without causing harm to your hot tub parts.

Method 2

This method is a lot easier because the jets themselves are used to remove oil and residue.

method 2
  1. Fill the hot tub to just over the jets.
  2. Add three or more teaspoons of dishwasher detergent and half a cup of bleach.
  3. Warm the water and turn on the jets for about 15 minutes.
  4. Drain the warm water.
  5. Fill the hot tub with cold water and run the jets for another 15 minutes.

Remember to wear protective equipment like gloves and goggles when handling bleach. Note: using bleach too often might dry out the gasket sealing the jets, so it's important not to overdo this method.

Key Takeaways: For general cleaning purposes, adding dishwasher detergent and bleach to the water and letting the jets do the cleaning will do just fine. But for a thorough clean, removing the jets and soaking them in vinegar and water is best.


Hot tubs offer the most relaxing and satisfying experience when you allow the jets to work at their best. You only have to do this once every three or four months or just about the same time when your hot tub water needs replacing. Choose whichever method works for you. Both methods work well whether you have the time or need to have it done quickly.
