This Penetrating Spa Cleanser is 100% guaranteed to clean away chemical residues which have built up deep inside your spa plumbing and pump. Simply pour  into your existing spa water and allow to circulate for 5 days.  It is highly recommended if you purchased a used spa or hot tub. These chemicals are oxidizers  that continuously eat away at spa plumbing, pump and seals, thus lowering the life expectancy of your spa and decreasing its efficiency. This 16oz bottle cleans up to 500 gallon spa. Two bottles are recommended if your spa is over 5 years old.

Why?

If you don't choose to use the Penetrating Spa Cleanser first, all the chemicals you have used in the past will slowly loosen from your equipment and your water will become hazy and have a chemical odor. You will also be sitting in toxic water when this chemical build-up begins to release. Using this cleanser first will help to lubricate your spas equipment, prolonging the life of your spa.
