i clean my mizzys after every round with soapy water and towel dry. never had to oil them yet. everyone comments on my new shiny irons (theyre 3 years old):thup:
I badly mistreat my 11 year old forged irons - that I've had for about 7 years. Still look lovely when cleaned! I use bike chain oil in the headcover of my mild steel putter though - covered in rust when i left it damp once, though it only took a 10min soak in Coke (well Pepsi) to take that off!
