Why wash your aircraft with Zi-400 HD Aircraft Cleaner?

Regular detergent washing with Zi-400 HD is an inexpensive way to protect aircraft from costly and potentially dangerous corrosion damage, and forms an integral part of any Corrosion Prevention and Control Plan (CPCP).

With each clean Zi-400 works its way into pores, cracks in the paint work and around rivets and fasteners, displacing moisture, dirt and salts from hard to reach areas that are highly susceptible to corrosion. In situations where corrosion has already set in, Zi-400 can swiftly reduce the rate of corrosion to almost zero.

Additionally, Zi-400 is a robust airframe cleaner. It successfully removes the most stubborn aircraft fouling from carbon deposits, exhaust stains, oils, grease, tyre rubber, hydraulic fluid and environmental contaminants such as salts, dust, bird excrement and atmospheric pollution.

Zi-400 will not damage or degrade paint surfaces and is highly suited for use on composite panels, titanium and matte finish paints. Zi-400 may be used as often as is necessary as there are no limitations on frequency of use.

The Science

Scientific testing of Zi-400 Aircraft Cleaner dates back to 1993, when the Australian Defence Force commissioned an in-depth study into the impact of 19 fully approved aviation cleaning products on the corrosion rates of aluminium alloy used in military aircraft.

The study found Zi-400 to not only be a powerful corrosion inhibitor, it also has the extraordinary ability to arrest existing corrosion after it has commenced, shutting down corrosion rates to almost zero. As a result, Zi-400 has been the trusted cleaning product of the ADF ever since.

In 2016, Solidus Industries commissioned Deakin University in Melbourne to undertake an in-depth assessment of Zi-400’s capabilities as a corrosion inhibitor. We asked them to recreate the 1993 testing by the Australian Defence Force, testing Zi-400 against a prominent aviation approved cleaning product that is currently used throughout the world.

“Zi-400 is great to use, unlike other aircraft cleaners you can let Zi-400 sit for a few minutes to soak those pesky bugs off the aircraft without leaving streak marks when washing off. Zi-400 can be used multiple times, the aircraft always look 10 times better than other aircraft cleaners.”
