What to do
Two ways to know aluminum cans from steel cans
The other way to tell the difference is by squeezing the can. If it easily starts to crush within your grip, then the can is almost certainly made of aluminum. Try crushing a soup can that way, for instance. Chances are that without superhuman grip, a soup can won't crush so easily. And by the way, soup cans are considered shredder materials-- you can still clean them up and bring them in to get a little more extra money, though. Just head over to a scale operator after you drop off those aluminum cans, and get paid for both types of cans. Got a piece of heavy machinery to bring in? Hey. Get paid for that, too!
