We really recommend using The Penetrating Spa Cleanser, especially on older spas. Older spas that have been using chlorine or bromine for 5 years or more require two bottles of The Penetrating Spa Cleanser to remove the residues that have built up over that extended period of time.
New Customers are recommended to purchase The Natural Hot Tub Co® Start Up Kit, this will give you one bottle of The Water Treatment and Conditioner, one bottle of Penetrating Cleanser to do the initial cleansing treatment, and one bottle of Filter Soak to clean your filters with, and you save money off the retail price too. You can save even more by bundling your Natural Hot Tub Co® products with a Micorpure prefilter or some of our SeaKlear products, these bundles are located on the Start Up Kit page.
The Penetrating Spa Cleanser will add years of life to your spa it's the natural solution.
THE NATURAL HOT TUB COMPANY® IS ABSOLUTELY THE BEST!!!
