摘要：
The invention concerns an aqueous corrosion-protective cleaning solution for tin-plated steel, in particular for tin-plated steel cans, the solution containing complex fluorides of the elements boron, titanium, zirconium, and hafnium; non-ionic surfactants; and corrosion inhibitors and having a pH within the range from 3 to 6. The invention also concerns an aqueous concentrate for preparing the solution by dilution with water and a method of cleaning tin-plated cans using the solution.
