My wife's aunt gave me these two pizzelle irons. One is fairly clean but the other is absoluteoly gummed up, so I thought this woud be a good chance for me to try cleaning aluminum. Since Michelle tipped us off on Dawn Power Dissolver, I ran out and bought a bottle. First I did the magnet check to make sure that they really are aluminum. Then I decided to just let the DPD do it's thing without scrubbing.
I liberally coated one side of the irons (since they're made of aluminum, shouldn't we call them aluminums? ;D) and left the other half as a control. After letting it sit for about three hours, I wiped it off with a paper towel and scrubbed a little bit with a toothbrush - nothing harder. After a water rinse, they results are in: The stuff really works!. It's not a miracle, since the crustier piece will need some elbow grease, but I was really impressed!
The pictures below are of the two irons (?) side by side; first, outside view before DPD, next outside after DPD and last, the inside view one side treated the other untreated. It'll take two more posts to get all the pics.
THANKS, Michelle, for giving up your secret wonder sauce! (by the way, it was only $2.29 at Walmart).
