Abstract (en)
[origin: US2007270323A1] A process for cleaning metal surfaces is provided using a neutral industrial cleaner, which comprises a combination of non-ionic surfactants and/or glycol ethers, and polyethylene imine. The cleaner has a demulsifying effect on fats and/or oils on metal surfaces and in the cleaning solution allowing separation and reuse of the cleaner. The cleaner is low-foaming and can advantageously be used in spray application.
