Abstract: The present disclosure includes arrangements, systems, and methods for removing mineral deposits. Disclosed is an aqueous solution within a container, with the container containing mineral deposits. The aqueous solution submerges the mineral deposits and may include at least one acid, or a combination of an organic acid and an inorganic acid in percentages that allow the replacement of toxic dangerous chemical ingredients. Disclosed also is a cathode and an anode within the container that are at least partially submerged within the aqueous solution. A direct current power source is configured to direct a voltage across the cathode and the anode to generate an electrical charge gradient within the aqueous solution.

Abstract: A corrosion inhibiting system for protecting joined dissimilar metals which are contacted by an electrolyte includes an anode electrode located in the electrolyte and adjacent to the less noble metal, and a cathode electrode connected to the more noble metal, the anode electrode and the cathode electrode being connected to the positive output and negative output, respectively, of a source of direct current for causing a direct current to flow through the joined dissimilar metals to inhibit the flow of corrosion producing local current between the dissimilar metals. The corrosion inhibiting system is employed in a hot water heater having a glass lined steel tank with a copper bottom head.

Abstract: A sample of hematite (Fe.sub.2 O.sub.3) is submerged in a solution containing about 14-55% by volume H.sub.3 PO.sub.4 balance water, or 12-45% by weight of H.sub.3 C.sub.6 H.sub.5 O.sub.7 and water, or a combination of both acids. A negative direct current electron flow above about 12 milliamps is established to the hematite as a cathode. The positive electrode can be constructed of copper to reduce oxygen emission from the reaction and is located in proximity but elsewhere. After a reaction time of about 60-120 minutes at about a 30 volt continuous direct charge, a weight loss of about from 0.3-0.5 grams should be measured from the hematite. An increase in current increases weight loss per comparable time unit measure.
