摘要：
A cleaning and anti-corrosion treatment for articles such as engineering parts and particularly for motor vehicles includes the following steps:-
(a) placing the vehicle in a chamber;
(b) closing the chamber;
(c) supplying a cleaning liquid containing a fat emulsifier to the chamber under pressure for a predetermined time;
(d) washing the vehicle with water;
(e) supplying a rust-removing and anti-corrosive liquid to the chamber under pressure for a predetermined time, and
(f) drying the vehicle as necessary and removing it from the chamber.
The anti-corrosive liquid used may be water-based and have the following composition per 100 ml of water:-
Citric acid (anhydrous) 3 to 52 grammes
Fat emulsifier 0.001 to 4 grammes
Corrosion inhibitor 0.001 to 3 grammes.
