I’m all about this goal. There are so many reasons to do it.
It’s better for the enviroment, better for our health, we both suffer from allergies and astma. It’s safer for the cats and it’s better for the wallet :-)

Right now I use only water and a swabb for the floors, it works amazingly well.

I use a spraybottle of water and sometimes a little dish soap.
I want to go back to use soap nuts but we ran out and haven’t gotten around to ordering new ones.

I clean the oven by coating it with soft soap and let it heat to 100°C for a little while and then letting it cool.
