I filled the tank to about 3/4 ths full with vinegar .

Marcmax told me he used a half cup of salt, if I remember correctly .

I also put the tank over a large plastic pan, with two pieces of wood for the tank to rest on, in case the rubber plug came out of the tank outlet hole .

1 Gallon of vinegar to 1 cup of salt is what I used. Vinegar was inexpensive ( about $0.75 per gallon) so I drained it and refilled it with fresh each day. Throughout the day I would turn the tank whenever I thought about it to insure all sides got covered. Just put rubber bungs in the fuel filler and petcock opening and bunched up an old towel to lay it on. At the end I rinsed it and flushed it with a baking soda solution to neutralize the acid.
