So, I've been making soap like no one's biz... and now I want to go to the next level... laundry detergent. It's economical, and I can use my homemade soap in it. The basic ingredients are 1/2 of Borax, 1/2 cup of washing soda, and 2 cups of grated soap. I had no problem finding the borax... but the washing soda, I couldn't find to save my life. You would think in an urban setting, I would have no problem finding it. So with a little research I found out you can make it! Washing Soda is Baking Soda cooked. By baking baking soda for about 2 hours on 400 degrees, the baking soda becomes washing soda. If you are interested in the chemistry of it... google it.... but I must say.... I am now a proud maker of laundry detergent. Two table spoons of detergent into the load... and I have clean clothes!
