Conker Laundry Liquid

Did you know you can make your own washing detergent from Conkers!  Conkers are the brown seeds from the Horse Chestnut tree and can be found in the UK towards the end of Sept, beginning of October when they fall from the trees.

When the conkers fall they are encased in a green spikey shell, inside the shell the conkers are brown and glossy.  When the conkers fall from the tree they are usually ready to collect and the outer spikey green shell usually splits when it hits the floor to reveal the conker.  If there are any that aren’t split you can lightly put your foot on them to split the outer shell.

Before you start foraging for Conkers to make your own washing detergent it’s worth remembering that you can’t eat them as they are poisonous to humans and most animals, icluding dogs.
