Before using Spa Solution we highly recommend using The Penetrating Spa Cleanser.
The Penetrating Spa cleanser will remove chemical residues which have built up deep inside your spas plumbing and pump. These chemicals are oxidizers (chlorine and bromine in particular, bromine being the worst) that continuously eat away at spa plumbing, pumps, and seals, thus lowering the life expectancy of your spa and decreasing it efficiency.
What happens if I don't use The Penetrating Spa Cleanser before using Spa Solution? Five to eight weeks into use, Spa Solution will continuously seek out chemical residues to eliminate them. When Spa Solution finds those residues the water might turn a bit cloudy and give off a slight organic odor. Using The Penetrating Spa Cleanser eliminates this problem.
We really recommend using The Penetrating Spa Cleanser, especially on older spas. Older spas that have been using chlorine or bromine for 5 year or more may require two bottles of The Penetrating Spa Cleanser to remove the residues that have built up over that extended period of time.
The Penetrating Spa Cleanser will add years of life to your spa.
