What you need:
1 Cup Baking Soda | 1/4 Cup Citric Acid | 1 Tablespoon Dish Liquid (any brand will do) | Silicone Ice Cube Tray | Airtight Jar or Container
Directions: Add one cup of baking soda to a large bowl. Next, add 1/4 cup of Citric Acid. Squirt in 1 tablespoon of dish liquid… you can use any dish liquid you like. Mix together well using your hands, a spoon or a whisk. Now press the mixture into your silicone molds or an ice cube tray, making sure to wipe any excess away. Let them dry for at least 4 hours or overnight. Once they are completely dry, gently pop them out and store in an airtight container. To clean and deodorize your toilet, simply toss a toilet bomb into your toilet bowl. It should start fizzing, which means your toilet cleaning bombs are doing their work!
