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.
