Apple Cider Vinegar is a popular choice for rust removal in older metal gas tanks… but how much rust is too much for it to work?
I dive in with a camera scope to see results!!
I love garage chemistry.

I love the video. If you were able to get inside and do some scrubbing along with the vinegar, I'm sure it will be fine. Great video!

degreased first? If a oily film was protecting the rust from the vinegar, it could take weeks

1 gallon vinegar, 1 cup salt, 1 cup dish soap makes about a gallon of weed killer.
