The Science

Scientific testing of the Zi-400 formula 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.

Suitable for use on any surface where corrosion is a concern and all surfaces that tolerate water including paint, varnish, fibreglass, gelcoat, metal, plastic, wood, glass, vinyl, leather and fabrics.

Zi-400 Industrial is a quick-break cleaner, making it suitable for use in oil water separators.


  1. For optimal results, dilute Zi-400 Industrial in warm water where possible (between 30-45°C max) to further accelerate the cleaning action.
  2. Wear the required Personal Protective Equipment (PPE) as outlined in the Safety Data Sheet (SDS).
  3. For general cleaning, begin the wash with a 1:30 ratio. For heavily soiled areas, make the mix stronger (1:5 ratio at the highest) and apply with a spray-bottle. Recommended application methods include: a good quality brush, sponge, spray-bottle or for maximum efficiency, foaming equipment.
  4. Zi-400 Industrial must be agitated on the surface and rinsed off with water before it dries. Allow a dwell time of a couple of minutes for the product to sit, so as it can lift the grime from the surface before rinsing. Applying Zi-400 with a foamer is a great way to increase dwell time for the product without drying.
  5. Rinse off with water. Zi-400 is naturally water repellent, making for quicker drying times.
  6. Wash regularly with Zi-400 Industrial to maximise corrosion protection.

“As a manufacturer of elevating work platforms (cherry pickers), we use Zi-400 at the final stage of production to clean the work platform, bodywork, accessories and vehicle, before presenting the finished work platform to our customers. Overall, we find Zi-400 to be highly effective, without being too ‘harsh’ so as to damage the surface finish of painted, powder coated and gelcoat items as is the case with many other cleaning products. Zi-400’s credentials enable us to have minimal impact on the environment, which fits in with our environmental policy.”

Paslode Zi-400 Industrial Testimonial

“Just a note to say how impressed I have been with Solidus Industries Zi-400 Industrial Cleaner. Previously it has been very hard to find a cleaner that ticks all the boxes for performance, cost effectiveness and is environmentally friendly. I have found the cleaner to be extremely effective for cleaning dirt and carbon deposits from Paslode Impulse and pneumatic tools. I have also found it effective in removing road grime from motorcycles and motor vehicles. The results are shown to the service agents that I train who have often taken up the cleaner to replace the cleaning methods they previously employed.”

“I am writing to let you know how pleased we are with the Zi-400 Industrial you supplied for our application. We have a 300m by 50mm pipeline used to carry Naphtha from the processing plant to a storage tank. Over time this line has been clogged up with a very viscous Glycol based material that had built up on the inside of the pipeline causing a 5mm reduction of internal diameter. We mixed the Zi-400 to 10 parts to 1 and proceeded to pump it backwards and forwards through the line. I would not hesitate recommending this product to anyone who has similar applications or where safety and environmental issues are paramount.”

“I have been running my own carpet and upholstery business for 5 years. One of the services I provide is mattress cleaning using a steam vacuum machine. I have never used any product that has been as effective as Zi-400 Industrial. I have also used Zi-400 on carpets and upholstery. This product is just as effective as the harsh products I have been using. My business has moved to using Zi-400 permanently because it is safer, better for my own health and my clients. I feel empowered to offer a safe cleaning product that can do mattresses, car interiors, carpets, and upholstery.”
