Here’s what you need (a lot of these items are household staples): – One bar of soap (try to get a non-toxic one) – One box of washing – One box of borax (this is not necessary, but I’ve found it really kicks the cleaning up a notch – one box of borax will contain more than enough for tons of batches of this homemade detergent – if you decide to use this, be careful) – A five-gallon bucket with a lid (or a bucket that will hold more than 15 litres) – Three gallons of tap water – A big spoon to stir the mixture with Put about four cups of water into a pan on your stove and turn the heat up on high until it’s almost boiling. While you’re waiting, whip out a knife and start shaving strips off the bar of soap into the water, whittling it down. Keep the heat below a boil and keep shaving the soap. Eventually, you’ll shave up the whole bar. Stir the hot water until the soap is dissolved and you have some highly soapy water.
