Ideal for vehicle undersides, brake discs, and hollow voids, it neutralizes corrosive salts and prevents flash corrosion after cleaning. Safe on painted surfaces and compatible with pressure washers, this 500ml bottle offers professional-grade protection for cars, bikes, and machinery—perfect for millennial managers who demand lasting performance and sleek aesthetics. ## Description Atom-Mac is a migratory and contact corrosion inhibitor that is diluted in water before use. It provides protection against corrosion in both open spaces and hollow voids. The powerful migratory phase corrosion inhibitors are liberated from the product and are carried in vapour phase to form an invisible atomic shield against corrosion of ferrous metal. Protects vehicle undersides, water collecting voids, braking surface, suspension, bicycles, garden equipment and machinery – wherever corrosion may occur. Can be added to rinse water to prevent flash corrosion of grit blast or surfaces chemically cleaned with Deox-C or Deox-GEL. How To Use: Dilute from 2 – 5% in water and spray onto surfaces to be protected. Atomise onto brake discs and surfaces after washing the vehicle and allow to dry (use 1-2% in water on motorcycles and bicycles and 5% on cars with disc brakes). Atomise into voids to protect interior surfaces at a rate of 2ml (of neat product) per litre of space. Atom-Mac should be diluted to 2- 5% to neutralise corrosive winter road salt and sprayed liberally on vehicle undersides this rate also provides invisible protection to bicycles, machinery tools and equipment. To use following Deox-C or Deox-GEL, or blast cleaning treatment, 2% added to the rinse water is sufficient to eliminate flash corrosion and protect the treated item. Sealing in a plastic bag or container traps the migrating corrosion inhibitors and adds further protection. Atom-Mac can be used in pressure washers and can be applied to the entire underside where it will neutralise road salt and emit power corrosion inhibitors. It should be applied at the end of each wash. Even wet cars can be put into storage allowing the migratory inhibitors to protect the entire vehicle. Aim for 2% Atom-Mac strength from the pressure washer nozzle. Review: Quality product - Does what it says it does and does it very well 100% recommend Review: Excellent - I primarily bought this to spray on my brake discs after washing the car. I hate how the discs turn orange after the wheels have been cleaned, it ruins the appearance of it. A few sprays of this on the brakes immediately after cleaning and it helps to seriously reduce the surface corrosion on them. I also use it once a week to spray under the car to add a protective layer to it and prevent corrosion. With the poor weather just now and the amount of salt and grit on the roads, 5 minutes spraying this under the car is enough to get rid of the grit from it. One thing I would say though is that deionised or distilled water is the best option when diluting this. I made it with tap water and the effects weren't great at all. Switching over to deionised water made a massive difference. I use it at a dilution ratio of 5% in a 500ml bottle so it'll last me a long time. ## Features - Causes serious eye irritation. - atom-mac is a migratory and contact corrosion inhibitor that is diluted in water before use. - It provides protection against corrosion in both open spaces and hollow voids. - The powerful migratory phase corrosion inhibitors are liberated from the product and are carried in vapour phase to form an invisible atomic shield against corrosion of ferrous metal. - Protects vehicle undersides, water collecting voids, braking surface, suspension, bicycles, garden equipment and machinery - wherever corrosion may occur. - Can be added to rinse water to prevent flash corrosion of grit blast or surfaces chemically cleaned with deox C or GEL for example.
