Here’s what you need:
160g baking soda
60ml lemon juice
1 Hydrogen peroxide (3 %, easily available at any pharmacy)
15-20 drops of any fragrant oil
Mix the baking soda and the lemon juice in a small bowl. In a separate bowl, mix the hydrogen peroxide and vinegar. Add this mixture in the baking soda-lemon juice mixture one drop at a time. In the end add a fragrant oil of your choice.
Take a spoon and make half-ball shapes. Place these on some parchment paper to dry. These toilet fizzies take a minimum of 4 hours to dry, but if you aren’t in a hurry, you’d better leave them to dry overnight. When they are completely dry, store them in an air-tight glass jar near your toilet.
Whenever you see that your toilet bowl is ready for cleaning, just drop a tab. You can do this as often as 2-3 times a week.
