I had this bright idea to make a toilet cleaning bomb! So far it seems to be working.
Here is my recipie if you want to try making them!
1 brownie bite pan or mold of your choice
1cup citric acid
2 cups baking soda
1 teaspoon dish soap
bleach in a spray bottle ( use in well ventilated area)
Add baking soda and citric acid to a stand mixer with a wire whisk attached. Turn mixer on low speed and add dish soap. Let this mix well. Start spraying mixture with bleach. DO NOT OVER SPRAY MIXTURE! Once it is the consistency of wet sand pack tightly into mold. Allow to dry over night. Carefully unmolded. Store in air tight container until needed. I find two squares work well!
