Abstract
A method for removing rosin soldering flux with aqueous cleaning compositions. The aqueous cleaning compositions can be employed for household use or for cleaning electronic circuit assemblies. The aqueous cleaning compositions contain an alkaline salt, an alkali metal silicate to boost detersive action or to provide corrosion protection to the substrates which are cleaned and an anionic polymer of a high molecular weight polyacrylic acid which stabilizes the alkali metal silicate to prevent precipitation of the silicate from solution.
