The best way to dispose of paint is to deliver it to your local specialist waste recycling centre. If you do not have access to one of these, let the paint dry fully, adding sawdust or cat litter as needed, before putting it in the dustbin. Don't throw it down the drain, because it is toxic and it interferes with the processes of water treatment plants.
