Cortec's VpCI-406 cleaning concentrate attacks winter salt corrosion from two angles. The first is removing salt, grime, and road spray from a vehicle body as soon as possible. This is a critical part of basic fleet maintenance because it minimizes the amount of time that chlorides have to start eating away at the metal. The second is the fact VpCI-406 contains corrosion inhibitors that provide protection against flash rust immediately after washing, with potential lingering effects for several days depending on specific circumstances and the environment.

In addition to its corrosion-fighting benefits, VpCI-406 has several positive cleaning qualities that recommend it as a truck washing choice in winter or summer.

The phosphate-free solution is highly concentrated, but is also available at custom dilutions to meet the user’s need. It can be metered into automatic bus/truck washes or used with power wash equipment.

VpCI-406 also has water-softening properties for use in hard water. It provides good foaming action and does not leave behind spotting or streaking, according to the company. 

Although road maintenance vehicles need it most, VpCI-406 can be used for any vehicle fleet exposed to harsh winter roads and corrosive deicing salts. The benefits of regular washing will accumulate over time, helping delay and reduce the amount of rust and extend vehicle service life, Cortec officials said in a press release.
