The acidic special cleaning concentrate for aluminium radiators, heat
exchangers and disk oil coolers


The high concentration of wetting and desperation agents together with inhibitors, combined with mild phosphorous acid, make AUCO ALU - B - an environmentally friendly and ideal cleaner for aluminium, non ferrous metals and stainless steel.
Yon can easily remove soil containing oil-carbon, grease, calcification or layers of oxidation on aluminium, brass, copper, bronze, chrome or high-grade steel. Nonferrous metals are lightened up. Deposits of iron (Fe) on chrome steel get removed, the surface gets neutralised and the chrome layer will be protected. A protective anti-corrosion layer forms on aluminium. The inhibitors protect iron parts against acid and prevent unnecessary influences on the structure of non - ferrous metals.

AUCO ALU - B - does not contain chlorinated hydrocarbons such as TRI - or


For cleaning of oil-coolers and heat exchangers as well as removal of oil carbon, soiling and calcification from radiator fins, inside and outside. For the removal of oxidation layers and to lighten up non-ferrous metals. For cleaning aluminium surfaces, containers, tanks, trucks, truck body facades and all devices or parts made of aluminium. For cleaning copper, brass and bronze. Ultrasound considerably speeds up the cleaning process !


In immersion bath mix 1 : 5 with water and immerse parts for 10 up to 60
minutes. Immerse heavily soiled oil-coolers, finned radiators, engine heads with radiator fins etc. for 1 - 5 hours - overnight the longest. Rinse well with highpressure cleaner, pulse spray or hard jet of water. A shiny gloss will appear on aluminium and brass. Copper and brass can quickly develop a natural patina.

Anorganic acids, anionic & non-ionic surfactants, inhibitors, colour- and helping agents.
