Abstract
A method of treating a chromium electroplating bath which contains an alkyl sulfonic acid to prevent heavy scale build-up of lead dioxide on lead or lead alloy anodes used therein is described herein. The method involves applying a voltage across the electrodes in said bath which is greater than the normal operating voltage during electrodeposition of chromium.
