Ivy is available in almost every garden and it is easy to make a chemical-free detergent.
How to do you can watch in my subsequent video.
You need 10 - 15 Ivy leaves and a laundry net.
Mince the leaves and put it in the laundry net. Then you put the laundry net directly into the washing machine.
Then start your program without any washing powder. The video is in german, but you can see what I do.
The result was surprising to me. Very clean clothes and a fresh smell.
