Chop or grate your soap. I don’t grate my soap because I’m clumsy and always seem to grate my knuckles, so I just chop it up as fine as I can. If you have a food processor, by all means, throw your soap chunks in there for a spin to get them supah-fine. Add the soap to your large bowl along with 2 cups of oxygen cleaner.In a small jar, combine your borax and about 20 drops of lavender essential oil. Mix the two together until there are no lumps. I press the lavender oil into the the borax until the lumps are gone.Add the borax to the large bowl and mix it together with a whisk or fork until everything is evenly combined.Store it in a quart jar and use 2 tablespoons per medium load of laundry!
