How do I get rid of surface rust?
This may help you out:
Thanks, Jeremy for your quick response! Someone also suggest ketchup! See pic of the issue we try to tackle.
Appears you have a leak or condensation. Have that checked out. You can use a green kitchen scrubby and WD40 to remove the rust.
I would use any of the powdered cleansers, but especially Barkeeper’s Friend. ☺️
