I have been using my own DIY Toilet Bowl Cleaner for a long time, but I like the idea of having something to freshen up the toilets between cleanings… Enter DIY Toilet Bombs.
What You Need to Make Toilet Bombs

- Baking Soda
- Citric Acid– Citric Acid can often be found in the canning section of you local grocery store.
- Immune Supporting Essential Oil– Not sure where to buy essential oils? Check out this post.
- Lemon Essential Oil
- Water- Preferably in a spray bottle
- Silicone Mold– You would think you could find silicone molds all over the place, but I had the hardest time, so I ordered one on Amazon that was perfect.
- Airtight Container for Storage
I did a little reading on citric acid… like, why is it used in cleaning? Apparently citric acid is a great antimicrobial that helps kill and prevent bacteria growth. Baking Soda is wonderful for absorbing odors, which, let’s admit, the toilet is known for. As far as essential oils, I chose to use an Immune Supporting blend and Lemon for a little extra cleaning boost, but other recipes I found use 30 drops each of Peppermint, Lavender, and Lemon. It’s up to you which route you want to take.
How to Make Toilet Bombs
In a bowl, combine 1 1/2 cups baking soda and 1/2 cup citric acid. Give it a good stir until well mixed.
Add the essential oils (totally 80-90 drops*), and continue stirring until the oils are thoroughly mixed in.
*I used 40 drops Lemon and 40 drops of an immune supporting blend.
At this point, you’ll want to add small amounts of water until you reach the desired consistency. I decided to use a spray bottle and add a couple sprays at a time, stirring in between to check for consistency.
You’ll know you have added enough water when the mixture holds its shape when squeezed in your hand. I noticed the mixture still looked powdery in the bowl, but because it held its shape in my hand, I was done.
Spoon the mixture into a silicone mold and press firmly. Allow this to sit at room temperature for 6-8 hours, or overnight.
Once dry, pop the toilet bombs out and place them in an airtight container.
When you’re ready to use the toilet bombs, add two to the toilet bowl, close the lid and let them dissolve for 20 minutes. You are certainly free to scrub with a toilet brush, or simply flush them down. Done. Your toilet should smell fresh and clean.
*Please note that these toilet bombs are not going to remove stains or “markings”. They are simply meant to freshen things up a bit.

The toilet bombs turned out perfectly the first time that I made them.
I was trying to make 8 cannisters for Christmas gifts. I guess it’s the humidity or maybe using too much water –
but this time the balls are sticking together.
I have made these many times and have never experienced the bombs sticking together. I would guess you are correct in your thinking; perhaps they were still a bit wet when they went into the canisters. They really do need to be completely dry, otherwise the moisture will build up in the canister, and moisture can cause that stickiness you mention. Sorry they didn’t turn out quite right… that’s always frustrating.
Just saw you for the first time on “The Jason Show” and love using items on our shelves that can be used for my home maintenance but are also economical AND safe to us and the environment! Thank you for your tips!
This is an FYI for those who live out in the country on septic. Antimicrobials are harmful to the maintenance of septic, so don’t use products with citric acid too much or you run the risks killing the bacteria needed to break down sewage pathogens. I was excited to use this, but don’t want to create a mess with my septic…
This is awsome ! Thank u so much but if i make more than 2 where can i store them i know in glass container but how long can they be in the glass jar until next cleaning day? Are they good for a week should i store them in the fridge i just want to make sure that way im not making a new batch every cleaning
These last quite awhile… at least a month. I have never put them in the fridge. They are just in my cleaning caddy (in a glass jar) for when I clean toilets 🙂
They should last indefinitely as long as they are kept dry and in an air tight container.
Hi, Erin,
WOW what a great treasure find your site is for me! I’m a natural messy and I mean the BEST GIFT I can give my family this week is to clean with love. That’s why I love your DIY recipes!!
Question about the toilet bombs, do they need to be stored in a glass air tight container or is plastic OK?
I always recommend storing anything that contains essential oils in glass, however, because the ratio between essential oil and other ingredients is low (and the bombs are hardened), you could probably get by with storing them in plastic if that is what you have on hand 🙂
I’m really interested in trying your recipe for a few of my friends as Christmas gift options. How many bombs does 1 recipe make? Thank you!
Blessings
It depends on the size of your silicone mold. I would say 18-20 with in the mold I used. You might get a little more or less depending on how much you fill them. Hope that helps! Merry Christmas!
So could oils be purchased at Walmart? I’m on a very tight budget and Walmart is where I usually get most everything I need… btw, I have checked out a lot of things on your blog and I’m going to use a lot of the things I read!! Can’t wait to try the pumice stone on the toilet stains! Thanks for all the great posts!!!!
Essential oils are a bit tricky. Can you use the ones from Walmart? Absolutely. However, oils you buy in the store may contain additives and often don’t contain the same therapeutic properties. If you are simply going for smell, these would be fine, if you are looking for better cleaning properties, you’d want to go with a higher quality oil.
So happy to hear that you are enjoying the posts!
These turned out perfect with my first batch. However, the second batch seems to be raising and overflowing. Any idea why that is happening with the second batch and not the first?
While I don’t know for sure why that might happen, I can take my best guess: heat. When I first did this, I tried to speed the drying time by putting them in the oven on a very low heat (lowest setting my oven allows) and they rose up and were definitely larger than when drying on the counter. If your room’s temperature or humidity is higher for your second batch, this could be the reason.
Could these be dropped into the tank? Or should they just be dropped in the bowl & flushed?
Hi Michelle! Thanks for the question. You actually drop the bombs into the bowl of your toilet. Allow them to fizz for about 15 minutes, and then flush .
Why not just throw in 1 part citric acid, 3 parts baking soda and some smell good stuff into your toilet. You can even mix it up and just scoop it in followed by a few drops of something.. Then you don’t have to make the bombs. Just have granular cleaner. Seems like a lot less work.
I actually love your idea. I would certainly think leaving it in powder form would work just as well, and you’re right; less work that way 🙂
Will the oils harm the silicone muffin tray?
Great question Brandy! Essential oils (especially citrus oils) do break down plastics and rubber, however, from everything I’ve read, they do not break down silicone, so using a silicone tray should be fine when working with essential oils.
Thanks for the reply! Glad to hear you’ve not come across any issues with the oils + silicone.
