Make Chlorine dioxide solution at a strength of 28,000 PPM with this kit. Includes 4 ounces of Part A (28% Sodium Chlorite) and Part B (50% citric acid) Supplied in PET Plastic bottles with Glass droppers. Citric acid is the original solution for activating sodium chlorite. 17 years ago, when we first started, we originally sold the citric acid solution in a 10% strength as recommended by the early discoverer of MMS, Jim Humble. The problem was that we had to sell 5 bottles of citric acid for every one bottle of sodium chlorite. We discussed this with Humble and he eventually agreed that 50% was an appropriate and effective strength. We pioneered the effectiveness of the 50% solution and it is now the standard.

Unlike other sellers, we provide our kits with different colored bottles to avoid confusion when mixing the solutions. Some have questioned the use of clear bottles with hydrochloric acid. Hydrochloric acid is not light sensitive and does not degrade from exposure to light as sodium chlorite does.

Please Note: PET plastic (polyethylene terephthalate) unlike other types of plastic, PET plastic is not single-use -- it is recyclable, versatile, and made to be remade. There are no chemical phthalates or bisphenol A (BPA) in PET plastic, and therefore PET plastic does not leach these substances. PET plastic is approved as safe for food and beverage contact by FDA and similar regulatory agencies throughout the world, and has been for more than 30 years. It is BPA free, clear, strong, lightweight and 100% recyclable plastic.
