Dawn is the most amazing stuff. As are the other ingredients.
The other day I found a soup tureen for my set of dishes (Yorktowne by Pfaltzgraf) at the goodwill, it had the bottom and the ladle but no top and I got it for less than $5. As a collector who knows the ceramic ladle is the expensive part because they break, I snapped that up just for the ladle which I didn't have.
It didn't look so great at first, but after a gentle scrub with my Dawn and baking soda, it looks beautiful now!
