DIY Toilet Bombs

Cleaning the toilet is a daily thing for me with four sons.  I’m constantly looking for a faster and easier way to do it.  Nothing better than a toilet bomb for a natural and efficient way to freshen up your bathroom.   One batch of these makes 20 1 oz bombs and lasts me a full month!  You can also try your hand at DIY Reed DiffuserBathroom Refresher, or these awesome Odor Obliterator Spray!
 Eyebrow Tamer-2
What you’ll need:
  • 1 1/2 C Baking Soda
  • 2/3 C citric acid
  • 2T Vinegar *Update, I initially made these during a dry time of year, with a dehumidifier running, if those are the circumstances you may need to increase the vinegar slightly.
  • 60 drops Germ Destroyer or Germ Fighter
  • Tray or Molds (you can use a small muffin tin)
What you’ll do:
  1. Mix Baking Soda and Citric Acid.
  2. Add Essential Oils and mix.
  3. Spray vinegar into dry ingredients slowly mixing often.
  4. When the mixture is moist enough to stick (but not wet) put into molds.
  5. Allow to dry for approximately 2 hours.
  6. Pop out of molds and store in a jar in your bathroom.
To use:

Just drop into your bowl use a scrub brush and flush!  I’ll sometimes just drop into the bowl for a quick mid-week refresher.

    1. That’s such a great idea! I’ve made toilet bombs before and I love them. I just bought a big bad of citric acid so I can whip up a new batch. Love this!

  1. I was about to buy cleaner for my washing machine that cost almost $7 for 4 uses. As I read the ingredients I realized that it was just citric acid and baking soda with lemon. I remembered seeing this recipe so I thought I’d give it a try! I plan on using it for my toilets, washing machine, and garbage disposal. Just 1 caution, don’t add too much vinegar. Mine kept growing HAHA. I’m also making it with just the citric acid and baking soda then storing it in jar. When ready to use I’ll scoop some out and add a couple drops of lemon essential oil and vinegar.

  2. I made these .. and they turned out! yay! I think i might need a bit more citric acid? (i halved the reciepe as it was my first attempt) as they arent fizzing too much but i love the freshness of them! And so easy!! 🙂

  3. Clearly, I need to read the blogs more often! I’m going to try to make these. I’ll use different EO’s, but I don’t think that matters. Thanks for the wonderful hidden gems found in the blogs!

  4. Make sure you slowly add the vinegar or they will puff up. You can also use a spoon to scoop them onto parchment paper, that creates little “pucks”. They make the bathroom smell great!

  5. My house smells amazing… super easy clean up… fizzes nice in the toilet… easy and quick to make…
    But I added too much vinegar so they wouldn’t stop fizzing. got too pouffy. Will try again later. I’m sure these will dry and be fine to use. THey won’t be the ones I give away for gifts though… these are going to make the best xmas present ever!!!! You an even use one in with the dirty dishes! You can pop these into so many places! sinks. laundry. fuck it… toss it down the shower drain! bring it on… citric acid is the bomb bitches! ahahaha. lol. i hope whoever is reading this gets my humour. but seriously… citric acid is amazing. so is baking soda. so is vinegar. They would make a sweet superhero trio. throw in peroxide and hot water every once in a while… and don’t forget elbow grease. My husband’s elbow grease!!! ahahaaha. but seriously… i don’t scrub, I just use baking soda. (and if baking soda doesn’t work my husband scrubs it cuz he is about ten times stronger than me. It’s so great to have someone strong to scrub it so we don’t need to use nasty chemicals. )

  6. These turned out great and were very easy to make. It’s a great cleaner and refresher for the bathroom!

  7. Are these toilet bombs good for cleaning those hard-water and rust-like rings around the toilet bowl, or are they used more for light cleaning?

    1. I mainly use it for light cleaning, however I have noticed that it is helpful with hard-water, I haven’t had the opportunity to test on rust rings. Please be sure to let us know how it works for you!

    2. Add extra vinegar or even drain the bowl. add vinegar and then drop the bomb! I wonder what would happen if you added peroxide too. It’s great for stains. Citric acid is great for mineral deposits. hot works too. If you can add some boiling water that would help. Good luck! I suppose in this case it’s worth the onze of prevention!!

    1. I have done them blank and add 2 drops to each bomb. I’ll often make a master blend of 3-5 essential oils then do my 2 drops from that bottle. Would love to hear what combination you’ve come up with!

  8. I don’t recommend a sealed glass jar for these. If they are not completely dry, or if moisture gets in when you open it, they will put out the gas that makes them fizz. And a tightly closed jar can explode. I know because I’ve done it.

    1. Oh goodness that is scary! I’ll certainly keep that in mind and be very cautious to keep it all nice and dry.

    2. Thank you for that! I’m sure that it should have been obvious to me but I actually had thought of putting them in glass jars with cute labels for xmas presents. I’ll find something else for sure! I want it to be easy with a large opening so I use them lots. I wonder if there is such a thing as too many toilet bombs in a day

  9. I have a silicon muffin pan. Should these pop out of the wells cleanly or are they kinda sticky on the bottom? The first few I took out were sticky and I molded them in my hands like a meatball before putting it in the container, but I’m leaving the other ones in the pan a while to see if they come out more easily after more drying time.

  10. When do they stop expanding? I have had them drying for about an hour and they keep getting bigger and bigger! And is it better to use silicone molds or is a regular mini muffin pan ok (I used one from my kitchen but did not use EOs in it – I will add those when I use them!).

    1. Mine probably grew about 20% and I think silicone molds are easier to pop them out of but a regular muffin pan is perfectly fine 🙂

    2. Same thing to me! lol. I used too much vinegar. The mix didn’t seem to be sticking and I think I gave it like two squirts too much. Every squirt really counts! THAT”S WHAT SHE SAID!!! lol. that joke just never gets old for me! I think next time i’ll test it with my hands more often. Maybe it’s like that kinetic sand. I’m sure we’ll eventually get it just right 😉

    1. Unfortunately I don’t have much knowledge in this area, a call to your local plumber may provide some answers.

    2. We are on a septic system and have been told that bathroom and kitchen cleaners often
      contain a category of chemicals known as quaternary ammonium compounds, such as alkyl dimethyl;
      benzyl ammonium chloride. The key ingredientin most liquid bleaches is sodium hypochlorite. The ingredients in these toilet bombs, particularly considerng the very small amount of each ingredient used in each one, diluted in the amount of water, both in the bowl AND the amount of water that flushes it all down renders these cleaners safe to use as directed, per my plumber. There are many articles on the internet about using household cleanser uses and their effect on septic systems. I would never advise that you dump large amounts of anything down the drain/toilet/sink/washing machine/ other than water, but this natural cleaner is safe ***when made and used as directed***. Don’t dump any single ingredient down your toilet – common sense, people!

      1. Thank you so much for this information, we get this question a lot and it’s good to know that it is safe to use in the manner 🙂

    1. It has a more course consistency, similar to salt. I know many people find it in the canning section of their local super store, I got mine from amazon.

  11. Would it work to make blanks and add the eos when I’m ready to use to avoid evaporation (very dry here) or would that be to much liquid and cause them to start fizzing in my hand?

      1. If you store them in a sealed container like a jar or glass container (rubber seal), evaporation wouldn’t be an issue, would it?

        1. Miranda that’s exactly what I do, this batch makes enough for a month for me and I keep it in a jar under the sink. Anything to simplify my life a bit 🙂
