To complete my homemade cleaning kit I decided to make the easiest version possible of liquid dishsoap. If you are well practiced at making soap and you have the supplies and time to make it from scratch, I am sure it would end up more cost effective (I suggest visiting Down to Earth for more on making liquid soap from scratch), however here is a simple recipe to get you started, cut costs and stay green. By using fairtrade liquid castille you can also be sure that your soap was made as ethically as possible without harming humans or animals in the process.
2 cups liquid castille
1/2 cup warm water
4-5 drops essential lemon oil
Pour ingredients together into a squeeze bottle and shake.
Smells fresh and works a treat!
