Abstract
Vanadium-containing deposits are removed from surfaces by treatment with a solution containing (a) a peroxide, and (b) at least 0.1% by weight of a peroxide-compatible wetting agent. (a) preferably comprises a 2-20% solution of hydrogen peroxide. (b) is most suitably a sodium alkylaryl sulphonate in an amount of 0.1-0.2%, but may also be an alkylphenol polyglycol ether.ALSO:Vanadium-containing deposits are removed from metal surfaces by spraying the surfaces alternately with a liquid, preferably aqueous, composition comprising (a) a solution of a peroxide and (b) at least 0.1% by weight of a peroxide compatible wetting agent and with water. (a) preferably comprises a 2-20% solution of hydrogen peroxide, while (b) is most suitably a sodium alkylaryl sulphonate in an amount of 0.1-0.2%, but may absorb an alkylphenol polyglycol ether.
