Homemade Powdered Laundry Soap | ThriftyFun
5/31/2015·1 cup washing soda; 1 cup baking soda; 1 cup grated laundry soap such as Zote or Fels Naptha; cheese grater; empty storage containers; Steps: Grate your bar soap. It's actually really fun to do this. My kids kept calling it "pink cheese", lol. :) Store the remaining soap in a Ziploc. Be sure to label it properly so everyone knows it's "not" food.
