Leisure Time 45450-02 Jet Clean, 1-Pint, 2-Pack

I used the product on a used hot tub I recently purchased. It left a ring of bio gunk around the top of the tub and loosened up some gunk. I am now using a five gallon white vinegar treatment which also works well but takes longer than the leisure time product. I recommend this product but it is too earlier to tell if I believe white vinegar or this product works better. Note that after using this product I used my pressure washer by taking the jets out and running the pressure washer through the lines. The pressure washer got a lot more biofilm out of the lines than the leisure time jet clean….going forward I will use both a foaming product like leisure time jet clean as well as my pressure washer though I still haven’t gotten all the biofilm out of the tub….each time i try more comes out. The prior owner did not take care of the tub….this is the last time i purchase a used hot tub.
