Abstract Process for cleaning rolling oils which, when contaminated, contain rolling fines originating from metals being processed into semi-finished products in strip form, in particular light weight metals, e,g, aluminium fines. An addition of 2 to 8 g of dimeric acid is made to each 1000 g of contaminated oil and the mixture passed through a coagulator whereby the rolling fines coagulate and can be readily removed from the contaminated oil. The purified oil can be recirculated as rolling oil.
