Completely stops formation of red rust inside water pipes

Reduces existing red rust (iron hydroxide oxide) to black rust (magnetite) and provides complete protection against rusting throughout pipework.

What is black rust (magnetite)?

Black rust is a hard crystal substance with its cubic size less than 1/10 of that of red rust. It was used as an anti-corrosive substance through the ages as surface coating of cooking utensils, such as traditional frying pans and teapots, as well as steel locomotives.

Extends life span of water pipes for more than 40 years. Provides with protective coating of magnetite to inner surface of pipes.

Clears clog by reducing red rust to magnetite, which cubic size is 1/10 of that of iron hydroxide oxide.

Completely solves water discoloration caused by internal corrosion.

Costs less than 1/10 of that of pipe replacement
