How to Clean and Maintain Hot Tub Jets

Hot tub jets help circulate water, provide massage, and create a relaxing spa experience. But over time, body oils, hair, dirt, and product residue build up inside the jets. This buildup can clog your system, reduce pressure, and even lead to bacteria growth.

If your jets are not flowing as they used to, or if your water has a strange smell, it may be time for a thorough cleaning.

Signs Your Jets Need Cleaning

Knowing when your jets need maintenance can help prevent bigger problems later. Look out for:

• Weak or uneven jet pressure

• Sticky or squeaky jets

• Cloudy water or foam buildup

• A musty or chemical-like smell

These signs are usually caused by gunk or biofilm collecting inside the jets.

How Often Should You Clean the Jets?

To keep your hot tub in top shape:

• Clean jets every 1 to 2 months for regular use

• Deep clean the whole spa, including jets, every 3 to 4 months during a water change

If your spa is used daily or by many people, more frequent cleaning is better.

Step-by-Step Guide to Cleaning Hot Tub Jets

1. Flush the System with a Jet Cleaner

• Purchase a jet line cleaner made for hot tubs

• Remove the filter before starting

• Pour the cleaner directly into the spa water

• Run the jets for 15 to 30 minutes to allow the solution to circulate

• Turn off the spa and let it sit for another 30 minutes to loosen buildup

2. Drain the Hot Tub

• Once the cleaning solution has worked through the jets, drain the water completely

• Use a wet/dry vacuum to suck out remaining water in the pipes and jet openings

3. Scrub the Jet Faces

• Use a soft brush or sponge to gently scrub around each jet

• If jets are removable, take them out and soak them in a mix of white vinegar and warm water for about 1 hour

• Rinse thoroughly before reinstalling

4. Refill and Shock the Water

• After scrubbing, refill the tub with fresh water

• Add the right amount of spa shock to sanitize the system

• Run the jets for 15 minutes to circulate

Tips for Ongoing Maintenance

You can avoid heavy buildup by adding a few simple habits to your hot tub routine:

• Rinse off before entering the tub to reduce oils and residue

• Use enzyme-based water treatments that break down waste inside the jets

• Keep your water chemistry balanced to prevent scaling and slime

• Remove and rinse the filter weekly to reduce strain on the jets

What If Your Jets Are Still Not Working?

If your jets are weak even after cleaning, the problem could be with:

• Low water levels causing air to enter the system

• Clogged filters that reduce flow

• Airlock issues, which can be fixed by loosening the pump fitting slightly to release trapped air

• Worn out jets that may need to be replaced

In some cases, a technician might need to inspect the internal plumbing.
