Part 3 — Cleaning Steel of Grease and Stains

Reading edition

Grease and stains can be easily removed from steel with a mixture of unslaked lime and chalk powder, by rubbing it on the steel with a dry cloth. The best proportion for the mixture, which is easily prepared, is 1 part of lime to 1 part of chalk powder. The powder should be used dry. It is kept in cans for future use and can be used over and over again.—Contributed by Loren Ward, Des Moines, Iowa.
