i have a 1 gallon galvanized gas can that i bought new around 1969. it has been stored for a looonnng time. no rust inside but when i shine a light in it it has some white dust & flakes in it . it looks to be galvanized on the inside as well. what would clean out this residue. i had an old outboard gas tank that had some rust on the bottom. i put 2 tubes of daisy bb's in it & let it ride in my truck bed for a month. cleaned it right up but that won't work in this case. here's what i shook out of the can.
photo is of a similar can.
