Description

The Prestone Command HD100-6 is a heavy-duty cooling system cleaner designed for diesel applications. It functions as a two-part system: Part 1 is an acid cleaner that removes corrosion and scale without damaging metal components. Part 2 is an oil encapsulation system that strips grease and oil from surfaces and flushes them away. This cleaner helps increase system life and performance by removing build-up, grime, corrosion, and rust, while also eliminating oil and fuel contamination.
