Hello there,
I used to do cleans on banking halls and we had to clean the scuffs of desks, walls and door kick plate etcs we just used cream cleaner like jif but test the area first as it could leave a white mark if the surface isnt suitable.
Other item weve used before is like a wall eraser and looks like a big white sponge its sold tescos.
Hope that a help
