Value for money I found this product reasonably priced compared to other products.Quality product and easy to use. Makes easy work of cleaning the hot tub without any overpowering smells.

Very easy to use, just add it to your spa water and that's it. Nice clean hot tub.

Purchased this to clean my jacuzzi bath, seems to work well.

The dose isn’t quite explained well in the description. On the label it says 250ml for a hot tub clean not 50-70ml. But that’s still enough for 4 deep cleans. Added 250ml and ran system for an hour. Did a great job leaving everything squeaky clean. Will buy again

This is brilliant for ensuring my hot tub has been flushed out after not using all winter. It eliminates any build up of body oils etc in the internal pipes. You have to do a cold fill, add the flush, remove the filter and open the air flow then run the tub to let it do it’s job. As I don’t use my small hot tub in winter, I always use this use it at the beginning of the season and once during, then again at the end.

Never used a pipe cleaner in my tub before omg no oily sheen on top of the clean water like we normally get

Certainly freshened up our whirlpool bath and the injectors, quite alarming at how grungy all the pipework had become. First wash loosened all the residue, and the second rinse through seems to have left the the pipes really clean, with little debris washing out .

Needed a couple of cycles with about 300 ml. The spa had stood for a while and the cleaner took all but the deepest of chlorine stains away, so pretty good performance.
