A method for carrying out a dishwashing cycle in a household dishwasher includes performing a wash step and dispensing an amount of a combination product from a dispenser during the wash step. The combination product includes a rinse agent and a cleaning agent. The method also includes performing a rinse step and dispensing an amount of the combination product from the dispenser during the rinse step.

Substituted diphenols, phenyl ethers containing two oxygen atoms attached to a benzene nucleus, and naphthols are more practically effective than previously known additives in stabilizing tin (II) salts, in electrolyte solutions useful for coloring anodized aluminum by electrolysis therein, against oxidation to tin(IV) by reaction with ambient oxygen. Preferred additives include 2-tert-butyl-1,4-dihydroxybenzene, methylhydroquinone, trimethylhydroquinone, 4-hydroxynaphthalene-2,7-disulfonic acid, and p-hydroxyanisole. If p-toluenesulfonic acid or napthalene sulfonic acid are also used in the electrolyte, the throwing power can be greatly improved.

Process for dyeing anodized aluminum

A process for the electrolytic coloring of anodized surfaces of aluminum or aluminum alloys using alternating current or direct current superimposed on alternating current, the electrolytic coloring being carried out with an electrolyte which contains cationic organic dyes and, optionally, conducting salts.

Citric acid partial esters corresponding to the following general formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 represent hydrogen or a straight-chain or branched C.sub.4 -C.sub.20 alkyl radical or a metal atom, with the proviso that at least one but at most two of the substituents R.sup.1, R.sup.2 and R.sup.3 represent such an alkyl radical, or mixtures of the citric acid partial esters corresponding to general formula (I), are used for the extraction of iron from aqueous solutions.
