Hi, when i first removed the body from the frame i used cif, pan scrubbers a stiff brush, hot soapy water and i also used the steam cleaner at work, i think i cleaned it about four times. After the body was fitted i used steel wool with hot soapy water and this helped remove some of the scratches, but be careful not to remove the grain on the body, each time i clean it i use cif and hot water, this seems to do the trick.
Thanks for asking.
