Took the tank to the car wash with a can of gunk
Pressure washed the inside and out, Fill with Vinegar and let it sit for a day
washed it out and filled it with Blaster metal rescue for two days
Drained it and thought it looked really good, But I figure it is going to bee a week or two before I put the tank back in so I put a gallon of WD40 in the tank and sloshed it around to protect it for now
when I did the WD40 turned orange rust color and the tank got AMAZINGLY clean I will try to get some pictures, but man that scared me to see how rusty the WD40 seemed to have turne
