Product Details

Foam shows up at the worst time. You sit down, hit the jets, and the surface turns into a bubble bath thanks to body oils, lotions, detergent left in swimsuits, and sunscreen riding in on every soak. Paddle Hot Tub Defoamer handles it fast.

The concentrated silicone formula breaks the surface tension holding foam together, so bubbles collapse on contact. Pour 1 to 3 oz with the jets running and the surface flattens out in under 30 seconds. No haze, no film left behind, no pH swing to chase afterward.

It is built to fit the routine you already run. The formula is pH-neutral and plays nice with chlorine, bromine, saltwater, ozone, and UV systems, and it will not gum up jets or degrade seals. Safe for jets, pillows, filters, cold plunges, and inflatable spas. A 16 oz bottle gives you 5 to 16 doses depending on tub size.

And every bottle does a little extra good. A portion of each Paddle purchase funds the Doggy Paddle Initiative, our giving program supporting no-kill shelters and dog rescues across the country. Better water for you, better odds for a shelter dog.

Foam gone before I sat down

Kids had a bubble party in the tub and it was wall to wall suds. A couple ounces with the jets on and the surface flattened out in under a minute.

A little goes a long way

I use way less than I expected each time. One bottle has lasted me months and the foam still drops on contact.

Works on my cold plunge too

Bought it for the hot tub and ended up using it on my cold plunge after workouts. Same quick knockdown. Would buy again.

No oily film after

Some defoamers leave a slick on top of the water. This one just clears the foam and the surface looks clean again.

No residue Quick fix

FAQs

What causes foam in a hot tub?

Foam builds up from body oils, lotions, sunscreen, and detergent left behind in swimsuits. Once those collect on the surface, the jets whip them into suds.

A defoamer knocks the foam down right away, while regular water care and filtration handle the buildup that caused it.

How fast does hot tub defoamer work?

Foam typically collapses within about 30 seconds of pouring with the jets running. For heavy foam after a party or fresh sunscreen, give it a full minute and add a little more if needed.

Running the jets helps the formula circulate and reach the foam across the whole surface.

How much defoamer do I add?

Add 1 to 3 oz with the jets running, then reapply as needed. A 16 oz bottle delivers between 5 and 16 doses depending on the size of your tub.

Start on the lower end and add more only if the foam does not fully drop, so you use just what you need.

Will it affect my chlorine, bromine, or saltwater chemistry?

No. The formula is pH-neutral and tested to work with chlorine, bromine, saltwater, ozone, and UV systems. It targets foam at the surface without touching your sanitizer levels.

Keep your water balanced as usual and add the defoamer whenever foam shows up.

Can I use it in a cold plunge or inflatable spa?

Yes. It is rated for cold plunges, inflatable hot tubs, portable spas, and fountains, using the same 1 to 3 oz dose.

It is also safe for jets, seals, pillows, and filters across all of those setups.

Does it leave a film or residue behind?

No. The silicone formula breaks the surface tension holding the foam together and then disperses, leaving a clean, flat surface with no slick on top.

Once the foam drops and the jets have circulated for a minute, the water is ready to use again.
