Earlier I knocked over a reed diffuser on the wooden counter in the kitchen and in a panic I chucked it in the sink and cleaned up the spill. I would never normally as I know they can be toxic to marine life and obviously not ideal to be putting into the drains. Realised afterwards that the rest of the bottle had drained down the sink and Google has come up with all sorts of scary things about it containing formaldehyde and other nasties and now I'm panicking about it having been in the sink and the possibility of it being hazardous. Should I be worried? Obviously won't make the same mistake again.
