Navasol Hard water deposit scale remover

Navasol — effective, safe, convenient — it's worth it!

Hard water deposit scale remover for commercial and industrial water-handling equipment. 

Navasol cleaner is the most effective hard water deposit remover available. There is no other like it; that is why it has been granted a United States Patent. It is also odorless and safe. Its active ingredient is a derivative of a natural protein component and is used in certain medications, in food and food-flavoring agents, and as an antimicrobial agent. The active ingredient in Navasol also occurs naturally in the stomach during digestion.

To use Navasol, simply pour it into the vessel that needs to be cleaned, or pump it through deposit-laden pipes. It will dissolve the hard-water scale deposits immediately. Rinse the cleaned equipment with water. However, do not use Navasol to clean hot-water heaters that contain a magnesium rod. Navasol will react with the magnesium. Also do not use Navasol on galvanized surfaces because it will dissolve the zinc coating.

How it works:

Over time, calcium-containing scale deposits precipitate from water flowing through water-handling equipment, forming hard scale deposits on the equipment's surfaces. These deposits diminish water flow in pipes and nozzles and interfere with heat transfer in, for example, boilers and ice machines. Navasol quickly and completely removes the hard-water deposits in the water-handling equipment. In fact, it works twice as fast as other common cleaners.

Navasol Versus Other cleaners:


Besides filling the air with vinegar odor, it just does not work very well. Singerman Labs' testing showed that vinegar simply is not strong enough to remove all of the hard-water deposits from industrial and commercial equipment.

Sulfamic-acid-type cleaners

These are marketed in two forms, a powder and a liquid. The liquid is the same as the powder, except dissolved in water. In either case, sulfamic acid is a strong acid. It is corrosive and it is irritating to the skin and mucous membranes. In our tests, sulfamic acid took twice as long as Navasol* to dissolve hard-water deposits. When sulfamic acid is dissolved in water, it gradually turns into ammonium bisulfate, which is used in hair-waving preparations. Before all of the sulfamic acid is turned into ammonium bisulfate, an equilibrium mixture is established which contains ammonium sulfamate, widely used as a weed killer.

Citric acid

Normally marketed as a solid or as the solid dissolved in water. Citric acid is a non-hazardous, natural product. However, our tests show that its cleaning power is substantially inferior to Navasol's. The reason may be this: Citric acid can combine with hardwater deposits in your equipment to form calcium citrate, which is not soluble in water. This replaces the hard-water deposits with another insoluble deposit. The problem can be overcome by using enough excess citric acid to solubilize the insoluble calcium citrate and wash it out of the system. But how do you know how much citric acid to use to avoid insoluble deposit formation?

Hydrochloric (muriatic) acid

This is a very strong and dangerous acid. It is corrosive to skin, eyes, and mucous membranes, and it is toxic. If allowed into the air, it will corrode the metal surfaces of industrial and commercial equipment and the metal buildings they may be housed in. Hydrochloric acid should be handled only by trained personnel.

Phosphoric acid

Phosphoric acid is classified as a poison under the Federal Caustic Poison Act. It is “a chemical known to the State of California to cause cancer.” It also causes eutrophication of bodies of water when allowed to get into the water. That is, it causes excessive growth of aquatic plants, especially algae. The water is depleted of oxygen resulting in fish kills. Phosphate-containing products should not be used if a phosphate-free alternative is available.
