Cleanser 8 oz

Wow! What a difference! We could not get our water to balance but after running this and refilling the hot tub. It's running great!

My hot tub didn't have any issues necessarily. It's just been three years so I wanted to do a "full clean". Seemed to clean well. Hot tub looks great and water (refill) is clear. I didn't have to do a rinse cycle, nor did it leave any hard calcium or deposits that others said. I'd purchase again.

I've bought this 3-pack before, and want to check - is the Cleanser (green label) for cleaning the tub surface or for the plumbing? I drained it last night and am ready to refill.And if anyone is worried about multiple refills - Water is expensive in Florida. But the 250 gallon tub - it is ~$5 for each fill.

Probably the strongest purge product on the market. Only draw back it that is hard toCompletely flush out. Had to refill the tub with fresh water twice. But if you have a contamination problem this is the product to grab

I liked the job it did cleaning out hot tub plumbing.

I was put off by what this little jar costs... I used some other stuff before this that basically did nothing. This stuff is legit I made some poor choices as a new hot tub owner in maintenance, I tried I just didn't know what I was doing, I got biofilm issues in the lines the other chemicals did nothing this stuff made all the line clear and nice like new. I will buy this every time I change the water.

Did what was on the label for filtering, seems to have worked, algae population seems to be way down. After more time I will know more.

Easy to use, straight forward instructions. Yes, you have to fill and empty the hot tub several times, but only once a year. We turn ours off in the summer (it's inside and it gets too humid to use it), every fall I use this to clean out the system as you can't completely dry out the lines 100%. Fill the tub, put this product in, let it run for 24 hrs and drain, flush the lines and fill!
