What you need?
A handful of ivy leafs, a single sock (that´s super easy, there is always one as left over)
How you do it?
Just put the leafs into the sock, make a knot to keep them in their and of you go. Throw it in the washing machine. Press start and wait.
How to get ivy?
It grows everywhere. Just take a piece with roots, plant it in a pot and grow your own.
The laundry gets super clean and it smells like garden *mmmmhhhhhh*
