Toilet Bombs just might be my kids’ favorite blog recipe to date! Anything with the word “toilet” in it is hilarious if you are 4 and 6 years old! But, these are not a sweet treat for you to eat. They go into your toilet, to clean and disinfect!

Remember the scrubbing bubbles commercials? Those cute little scrub brushes working hard to clean your bathroom for you! Well, these little toilet bombs do the same thing, except they do not off-gas harsh chemicals or cause reproductive damage! #winning

Let’s take a look at what’s in those scrubbing bubbles that you see on TV:

  • Water: Provides a liquid base for a product
  • Butoxypropanol: Cleaning Agent. Breaks down dirt and deposits
  • Alkyl Polyglycoside: Cleaning Agent. Breaks down dirt and deposits
  • Polyethylene Oxide: Cleaning Agent. Breaks down dirt and deposits
  • Tetrasodium EDTA: Chelator. Removes soap scum and soils
  • Sodium Hydroxide: Adjusts the pH of a product to improve stability
  • Fragrance: Fragrance (remember, the word “fragrance” on a label is NOT reglated, it can be anything!)
  • Liquitint® Blue HP DyeDye: Provides a pleasing color for a product
  • Liquitint® Red ST DyeDye: Provides a pleasing color for a product

Health risks of toxic cleaners include:

  • Reproductive damage
  • Increase in cancer due to carcinogens
  • Damage to children’s delicate organs and immune systems
  • Skin and eye irritation
  • Aggravate asthma and respiratory conditions

I wanted to make something that had cleaning power, and was not filled with harsh chemicals that could lead to ill health! Essential Oil Toilet Bombs were the natural next step!

Here is the breakdown of what goes into my toilet bombs:

  • Baking Soda: for the fizz
  • Corn Starch: to bind
  • Citric Acid: citric acid is a chelator, this means that it’s an acid that inactivates water hardness and creates foam. This makes it especially useful as a cleaning agent. It helps get dirt and grime off of surfaces. Citric acid also prevents water spotting and hard water film. Citric acid is antibacterial and antiseptic too!

DIY Thieves Toilet Bombs

Prep Time: 10 minutes
Active Time: 25 minutes
Additional Time: 15 minutes
Total Time: 50 minutes

Make your own toilet bombs to clean and disinfect your bowl. They are easy to make without all the harsh chemicals that you find in store-bought varieties.


  • 1 cup baking soda
  • 1 cup corn starch
  • 1 cup citric acid
  • Water
  • Thieves Household Cleaner
  • 20-30 drops Thieves Essential Oil
  • Spray bottle (we re-use apple cider vinegar bottles when empty, and then add a spray top (see below))


  • In a gallon sized plastic bag, combine the baking soda, corn starch, and citric acid.

  • Mix water and Thieves Cleaner in spray bottle, according to directions based on size of water bottle and usage.

  • Using the spray bottle, spray water into the dry ingredients in the bag.

  • I spray 5-10 at a time, then mash the bag with your hands (make sure its sealed!).

  • Spray more water, mash, more water, mash. So this until the mixture just begins to hold shape.

  • Add in the Thieves essential oils and mix up again.

  • Press into silicon molds.

  • Allow to dry for 5-7 days (depending on your humidity). They will harden quite a bit and puff up.

  • Pop them out of the molds.

  • Store your toilet bombs in a glass jar or plastic bag. Keep them dry.

  • Drop bombs into the toilet and let them fizz.
  • The thieves cleaner, thieves essential oil, baking soda, and citric acid will fizz in the bowl and eliminate odors and grime.
  • Flush once the fizzing stops. You can scrub if you want to but the bubbles should do the trick.
  • If you want to give them more power, add an additional drop or two of thieves essential oil to the bomb before dropping it into the toilet.

  1. Was excited to try these. Cut the recipe in half since I only had 1/2c citric acid. i used the same mold you have and they foamed over the sides within 1 hr. I tried to re-mold and now those are foaming over. What in the world did I do wrong?

      1. Hi Kate! Just happened upon the blog. If the citric acid gets too wet, it will cause it to foam too much. Try a lighter spray or just a few sprays and then mix. You want to get it wet enough to start to hold together but not so much that it will start to activate. I learned this the hard way myself doing a different DIY mold. You can’t rush the spray the and mix.

    1. My molds foamed over like crazy, too. I live in Colorado, so maybe it has something to do with the altitude. They look like ginormous marshmallows puffs, spilling over the sides of my mold.

  2. I had the same problem of them foaming way up. I am guessing maybe I added too much water, causing them to over-react? Will try using less next time and not fill the molds completely.

    1. I just made these and had the puff-up problem…but I just kept pressing them down. After 2-3 times they didn’t puff up so much and I left them to dry. I did remove a little extra from the sides that made up a 1/2 bomb that I threw into my toilet and giggled when it foamed and fizzed…because I am that easy to entertain. They came out great!

  3. I have made this type of thing before, however I didn’t mould it, I kept it in a container with a plastic spoon held on with rubber band, in my cleaning bucket, just a spoon full does the trick & people love the scent. Thank you.

  4. How much of the thieves cleaner did you use? Going to give these a try but dont have silicone trays. Thinking of using tart trays lined with plastic wrap. Hopefully that will work ok

  5. I’m wondering… could we Make these into automatic toilet cleaners? Like the Lysol ones that you hook up inside the toilet bowl and every time you flush it cleans it?

  6. What size molds do you use for the theives toilet bombs? I just started using oils n I’m excited to try these !

  7. When your mixture fizzes up it means your mixture is too wet decrease the amount on liquid and they should not fiz! Good luck!
