Here is how to make your all-natural, no-scrub DIY toilet bombs:
No-Scrub DIY Toilet Bombs
Ingredients:
1 cup baking soda
2 tablespoons hydrogen peroxide
1/4 cup cream of tartar
20 drops lavender, rosemary, peppermint, or lemon essential oil
Instructions:
In a large mixing bowl, mix baking soda and the cream of tartar. Gradually add hydrogen peroxide, stir, and add the essential oil.
Next, pour the mixture into silicone ice cube molds, about 1½ inches in width, press firmly, and place them in a dry, cool place for 4-6 hours. When set, pop fizzies out of molds, and store them in a glass jar.
Next time you need to clean the toilet, just throw one of these toilet bombs inside the bowl, leave it to dissolve for about 10 minutes, and then flush. Repeat twice a week.
