Commercial toilet cleaners can have harmful chemicals—not only to the environment, but also to your health. You can still get the family throne sparkling clean by making a natural toilet bomb. Not only will this “bomb” deodorize the commode, but it will also destroy bacteria and keep you healthy.

Method 1 of 4:

Making Basic Toilet Bombs

1
Mix together the baking powder and citric acid in a glass bowl. Pour 1⅓ cups (240 grams) of baking soda into a bowl, then add ½ cup (150 grams) of citric acid. Stir both ingredients together with a wooden spoon.
2
Mix the essential oils in a spray bottle. You will need about 90 drops total of essential oil. You can use all one type, or experiment with different blends. Lavender, peppermint, and lemon are a great combination because they all have odor-eliminating and antimicrobial properties. Another option would be a combination of peppermint, tea tree, orange, and lavender. ^{[1]

- Make sure that the spray bottle you use has a light mist.

Mist the dry mixture with the oils while stirring. Go slowly and don't let the mixture fizz. If the mixture fizzes, that means it is too wet, and it won't work properly later on. You want the mixture to be damp enough so that it clumps together when you squeeze it. It's okay if it crumbles a little.^{[2]

- If it is still too dry, spray a little water onto it. Plan on using about 1 teaspoon. Again, don't let it fizz.^{[3]

Press the mixture into plastic or silicone molds. You can use silicone ice cube, cupcake, or bath bomb molds, all of which can be found in your local craft shop. You can also use plastic ice cube trays, soap making molds, or candy molds as well. Some people like to use mini muffin tins trays as well.
5
Let the toilet bombs dry for 6 to 10 hours. During this time, the moisture will evaporate and the bombs will harden. Do not remove the toilet bombs any sooner, or they may crumble apart.
6
Carefully pop the toilet bombs out. If the toilet bombs are still damp after you remove them, set them out onto a sheet of parchment paper and let them finish drying over the next few days.^{[4]

7
Use the toilet bombs once a week, or as needed. Drop one into the toilet. Wait 10 minutes, then flush the toilet. Scrape away any excess gunk away with a toilet wand.^{[5]

2
Stir in 1 tablespoon (15 milliliters) of liquid dish soap. You can use any type of dish soap you want, but make sure that it is not the foaming type. Use a fragrance that you like.^{[7]

3
Pack the mixture into a plastic or silicone mold. You can use just about anything here, from silicone ice cube molds to plastic soap making molds. You could even use mini muffin tins.
4
Let the mixture dry. This can take anywhere from 4 hours to overnight. Set the toilet bombs some place where they won't be disturbed while they dry.^{[8]

5
Pop the bombs out of the mold. If the toilet bombs feel a little damp, set them out onto a sheet of parchment paper to finish drying. Store them in an airtight container once they are completely dry.
6
Use the toilet bombs once a week or as needed. Simply plop a bomb into the toilet, and let it fizz. Flush the toilet after 10 minutes, then clean off any excess gunk with a toilet wand. Store the rest in an airtight container.

Method 3

Method 3 of 4:

Making Toilet Bombs with Borax

1
Combine equal amounts of baking soda, citric acid, and borax. You will ½ cup (90 grams) of baking soda, ½ cup (150 grams) of citric acid, and ½ cup (204 grams) of borax or cornstarch. Pour everything into a glass bowl, then mix it with a wooden spoon.^{[9]

2
Spray the mixture with water, then knead it. Alternate between squirting the mixture 2 to 3 times with water, then kneading it. You want the mixture to be damp enough to clump together when squeezed.^{[10]

- Use a mini spray bottle with a light mist to avoid getting the mixture too wet.
3
Add 25 drops of essential oils. You can use all one type, or experiment with different combinations to create a unique fragrance. Try refreshing fragrances, such as lemon, lavender, or rosemary. Mix everything again.^{[11]

4
Spoon the mixture into a plastic or silicone mold. You can use almost anything here. Silicone ice cube and cupcake molds work really well because they are flexible. You can also use a plastic ice cube tray or soap mold. As a last resort, try a mini muffin tin instead.
5
Let the mixture dry. This will take about 4 to 10 hours. Set the mixture some place where it won't be disturbed while it dries.
6
Pop the toilet bombs out of the molds. If they are still damp after you pop them out, place them onto a sheet of parchment paper and let them finish drying the rest of the way.
7
Use the toilet bombs. Drop one into the toilet and let it fizz. Flush the toilet after 10 minutes, then use a toilet wand to scrape out any excess gunk. Place the rest of the toilet bombs in an airtight container.

Method 4 of 4:

Making Toilet Bombs with Hydrogen Peroxide

1
Mix the baking soda and the citric acid. Pour 1 cup (180 grams) of baking soda into a glass bowl. Use a wooden spoon to stir in ¼ cup (75 grams) of citric acid.^{[12]

2
Pour the hydrogen peroxide and white vinegar into a spray bottle. You will need 1 tablespoon (15 milliliters) of hydrogen peroxide and ½ teaspoon of while vinegar. Make sure that you use a small spray bottle with a fine mist, otherwise, you risk spraying out too much liquid. Shake the bottle to mix the hydrogen peroxide and vinegar together.^{[13]

3
Spritz the baking soda mixture with the hydrogen peroxide solution. Knead the mixture, then spray it again. Keep doing this until the mixture clumps together when you squeeze it. Use about ¾ of the solution and save the rest for later.^{[14]

4
Add 15 to 20 drops of essential oil. You can use just one fragrance or a combination of several different fragrances.^{[15]
X
Research source} Try to use something that smells refreshing, such as tea tree, lavender, or peppermint. Be sure to knead the mixture well after you add in the essential oil.
5
Spoon the mixture onto a backing sheet. Pack the mixture into a teaspoon, then tap it onto a baking sheet. The mixture will hold its domed shape. You should be able to make about 40 toilet bombs.^{[16]

6
Spray the toilet bombs with the rest of the hydrogen peroxide solution. This will help them harden further when they dry and keep them from crumbling.^{[17]
X
Research source} Don't get too carried away, however; you only need to lightly mist them, not soak them.
7
Let the toilet bombs dry completely. This will take about 4 to 6 hours.^{[18]
X
Research source} Place the baking sheet some place where it won't get disturbed during this time.
8
Use the toilet bombs weekly, or as needed. Plop one into the toilet and let it fizz. After 10 minutes, flush the toilet. If there is any residue, use a toilet wand to scrape it out. Keep the rest of the toilet bombs in an airtight container.

If you have sensitive skin, it would be a good idea to wear some rubber gloves while working.
