2126969 9313246 PCTABS00024 In a method for cleaning articles, especially for removing flux after soldering, an article is contacted with a hydrocarbon-containing fluid containing one or more hydrocarbons selected from C8 to C15 paraffinic and naphthenic hydrocarbons and with an alcohol-containing fluid containing one or more alcohols selected from C5 to C15 straight-chain or branched-chain, saturated aliphatic alcohols. The hydrogen-containing fluid and alcohol-containing fluid are preferably in the form of a liquid mixture. Efficient cleaning of articles, for example of electronic components after soldering, is possible without the use of halogen-containing solvents.
