A jetted tub can be super relaxing, but those jets can get pretty gross if you don't clean them often. Just like a kitchen sink needs washing, the hidden parts of your tub jets can collect soap leftovers and grow bacteria if ignored. While it might look tricky to clean at first, keeping your tub fresh isn't as hard as you might think.
According to Matt Giovanisci, founder of Swim University, "A jetted tub that isn't cleaned regularly can spray out black specks of bacteria, mold, and mildew – all the nasty stuff that's been growing in the lines while the tub has been sitting unused."
The good news is that with some basic cleaning know-how, you can turn those dirty jets into streams of clean, refreshing water. Think of it like giving your tub a mini spa day – it needs care to keep giving you those nice, relaxing soaks you love.

Things to Do When Cleaning a jetted tub
Cleaning a jetted tub requires a systematic approach to guarantee all components are thoroughly sanitized and maintained. The process involves preparing the tub with the right cleaning solution, addressing both visible surfaces and internal plumbing, and properly flushing the system to prevent buildup and bacteria growth that can accumulate in the jet mechanisms and pipes.
- Turn off air induction valves – Prevents dilution of cleaning solution and guarantees concentrated cleaning power.
- Fill tub with hot water – Cover jets by 2-3 inches to allow proper circulation through the system.
- Add cleaning solution – Mix mild dish soap and white vinegar for effective cleaning and disinfecting.
- Run jets for 15 minutes – Allows cleaning solution to circulate through all pipes and components.
- Apply baking soda paste – Use on visible jet faces and crevices to remove stubborn grime.
- Scrub with toothbrush – Focus on jets, crevices, and hard-to-reach areas.
- Drain and refill – Remove dirty water and add clean water for rinsing.
- Run jets again – Flush system with clean water to remove residual cleaning solution.
- Final wipe down – Use microfiber towel to dry and polish surfaces.
Things to Avoid When Cleaning a jetted tub
When cleaning a jetted tub, it's essential to be mindful of certain practices that could damage your tub or create unsafe conditions.
Using the wrong cleaning products or methods can't only compromise the tub's functionality but also pose serious health risks and lead to expensive repairs. Understanding what to avoid is just as important as knowing the proper cleaning techniques.
- Harsh chemicals and bleach – Can deteriorate rubber gaskets and seals, leading to leaks and mechanical issues.
- Chemical mixing – Combining cleaning agents, especially bleach and vinegar, creates dangerous toxic fumes.
- Bubble bath products – Excessive foam clogs jets and leaves residue that's difficult to remove.
- Abrasive cleaning tools – Steel wool, stiff brushes, and rough sponges scratch and damage the tub's surface.
- Skipping regular maintenance – Allowing buildup to accumulate leads to bacterial growth and reduced jet performance.
- Hot water during cleaning – Using very hot water can damage internal components and warp plastic parts.
- Leaving jets dry – Running jets without adequate water coverage can burn out the motor.
- Oil-based products – These can leave residue that's difficult to remove and clog jet mechanisms.
