Abstract
Deposits are removed from surfaces by contacting the deposits with a deposit-removing liquid composition containing a substance which produces gas bubbles, and thereby stirs the liquid, at the conditions at which the deposits are contacted with the liquid. Where the substance is one which is a gas at atmospheric conditions but dissolves in the liquid at a super-atmospheric pressure, such as carbon dioxide, the pressure exerted on the composition while contacting the deposits is repeatedly raised and lowered whereby the gaseous substance is repeatedly liberated from solution and placed back into solution to promote agitation of the liquid.
