I’ve been making laundry detergent for almost a year now. I used almost the same recipe that was blogged about on the simple dollar except we use ivory soap. I also scent the final product with peppermint oil. I am not yet through with my box of borax and washing soda, I think I have a year’s worth left. Additionally, I use the borax for cleaning stubborn grease (like the stuff found on a stove). Its very effective.
