Looking for a bit of advice. Got a job to price and not sure what the best route to go down is.
Have been asked to clean Galvanised Steel roller shutters. Can't pressure wash them as its on a row of shops and will just cause a mess... So looking for advice on what chemicals to use etc.
It's just bare steel, not been painted, and is badly oxidised as well... Have advised it would be a lot easier to paint it, but they want it cleaned for some reason
