Central Scientific Company Anti-Stain Formulary

Hey, look - another wheel! In fact, we have FOUR of these all from the same seller. I don't know why she wanted to sell all four in a lot, but we have no complaints.

This is a nice stain remover wheel from the Central Scientific Company of Chicago. All four are in excellent condition.  The wheel measures 7 by 5.75 inches and is of a sturdy cardboard. The copyright date is 1915.

This is quite a list of chemicals, isn't it? It has everything from powdered chalk to potassium cyanide. You can get help removing "wagon grease" with this wheel. I wonder how often someone needs to remove tar from silk?
