Whirlpool systems are prone to develop a build-up of grime, oil, biofilm and general dirt and this can then lead to them working inefficiently. Our hot tub and whirlpool cleaner is sure to remove the biofilm, leaving your whirlpool as clean and hygienic as possible! Removes Oil, Grime, Biofilm and more! Pro-Kleen's hot tub cleaner is sure to remove grease, body oils, general grime and biofilm that can form deep within your pipework. If left untreated, this kind of growth and build-up can lead to your whirlpool system working less efficiently, and over time, it could even stop working completely. Recommended Use For optimum hygiene and working performance, we recommend that you use Pro-Kleen's System Flush with every water change for hot tubs and every 3 months for whirlpools. Easy To Use Our hot tub and whirlpool cleaner could not be easier to use! Simply fill your hot tub or whirlpool with water until it reaches the top of the jets and then add 500 ml - 1 L of solution (depending on how dirty your system is). Once applied, run for 15-30 minutes for a complete system flush!

Will it damage the filter?** A: I can speak for your hot tub, but ours can be run for a short time with it, I always remove my filter to clean that separately, soaking it over night. **Q: I can't imagine that 50-75ml of this product can replace true spa flush, which normally requires about 250ml or more to rid a hot tub of biofilm?** A: Hi, I can't help too much, but that is what it says on the container. It says you should do this every 2 -3 weeks though. For your information It does recommend 250ml for hot tubs as well . **Q: Can you use this on inflatable lay z spas?** A: Yes. **Q: How would I use this to clean a Miami layz hot tub? Does it need to be empty or full?** A: Not sure my jacuzzi bath fill to cover top jets run for 15 minutes then rinse to clean ## Customer Reviews ### ⭐⭐⭐⭐⭐ How much dirt and scum it gets rid of *by S***C on 8 May 2026* I was scepticle about purcjasing this product but i am amazed on how much crap and dirt this gets out havnt used the hottub in 2 years so def worth the money ### ⭐⭐⭐⭐⭐ Great for hot tub maintenance. *by C***S on 29 June 2025* Ideal for maintaining your hot tub or spa bath.
