Cleaning rust from old cans

[BenTheDigger]

Hi I came across some old beer cans from the 1930's and need help cleaning the rust off of them. I can see some color under the rust but barely. I heard some people use acid but these cans could be aluminum but I could be wrong. Does anybody have any ideas?Thanks,-Ben I have three cans like this:

Aluminum does not rust and acid will dissolve it. Oxalic acid is good. Vinegar or Lemon juice works too.

I can tell from the top lid that is not a 1930's can but more like a 1950's can. Send me pics of what they look like as is, I'll let you know if they are common or not & if even worth cleaning. Cleaning rusty cans is my Specialty. LEON. P.S. Pic velow of my half & half can.

Here is the pic of the bottle I have 3 like this and one dented one. If I look closely I can see some blue and other colors.

If I could see some color I may be able to decifer what it is. From what I can see I can't see any color. From that Pic I have no clue what it is. Maybe send them to me for a cleaning? LEON.

Here is a picture with color this can is dented and broken but also has the most color.

If I had to guess it looks like your holding a upside down Hamm's can. LEON.
