Restore Your Hot Tub to Pristine Condition — Fast

Foam is one of the most common and frustrating hot tub problems. It forms when body oils, sweat, makeup, deodorant, moisturisers, and sunscreen residue react with your water's alkalinity — and it won't disappear on its own. Left untreated, it indicates contaminated water that's neither clean nor safe.

Pro-Kleen Hot Tub Anti-Foam is a professional-grade, highly concentrated treatment that eliminates foam rapidly and effectively. Unlike weaker, diluted alternatives, Pro-Kleen's formula works at the molecular level — neutralising the oils and surfactants responsible for foam rather than just suppressing the bubbles temporarily.

Why caravanners, spa owners and hot tub enthusiasts choose Pro-Kleen: Simply add 50ml (2 capfuls) to your hot tub water, activate the jets to circulate, and the foam clears within minutes. At 100 treatments per 5L bottle, it delivers exceptional value compared to single-use sachets or smaller bottles sold at inflated prices.

Fully compatible with all hot tub types — including inflatable hot tubs, acrylic spas, and swim spas — and safe alongside chlorine, bromine, and salt water systems. Will not affect your pH, alkalinity, or sanitiser levels. Safe for filters, pumps, jets and internal components.
