Fabric care symbols

I see these symbols on the tags of my clothes all the time and wonder what they mean. Click the title to check out the webpage. I seriously would rather read "dry clean only" than try to decipher some obscure symbol. But now we know.... an X over a O means "do not dry clean". I would have thought they meant not to wash it. An "A" in a circle means any solvent can be used and a dash in a square means "lay flat to dry"... who would have known?

No wonder some people don't ever wash their clothes. They aren't really homeless they just can't read the darn tags!
