Huh. I'm not the one doing laundry in our household, and I still know all the four symbols that were hand-drawn on the paper there.

To remember that the circle is dry cleaning it helps to know that it can circumscribe letters indicating what type of dry cleaning process is allowed.

The tumble dry symbol just looks like a tumble dryer, and the washing symbol the same. Bleach is the tricky one but can be remembered because it's not one of the others.
