This fun little nuggets of citrussy-scented cleaning power are like bath bombs for your toilet, except instead of softening your skin, they fizzle away at your dirty toilet bowl. As far as toilet cleaning goes, these are actually pretty fun. That’s not much, but it’s something.


The basic premise and process is pretty much identical to that of bath bombs. High pH + low pH = fizz. And, when all the ingredients are dry, you can lighten moisten them and press them into shapes, and then let them dry, and have fizz at the ready.


Just a few changes were required make these cleaning toilet bombs instead of bath bombs. First off, I swapped out the baking soda (USA / Canada) for washing soda, which is a stronger base and cleaner.

Up next, I added ground soap and some ground up sodium percarbonate. Sodium percarbonate = Oxyclean, and you can make your own by mixing equal parts washing soda and hydrogen peroxide in a glass jar. It’ll be liquid at first, but leave it for a few days and you’ll have a jar coated in white powder. You can scrape that off into your DIY coffee grinder and blitz it into a very useful powder.

After that, there’s not much that’s too different. I would have left the epsom salts out, but they are wonderfully effective at helping the mixture form shapes when they get a bit wet, so in they stayed.

Lemon Eucalyptus Toilet Bombs

4 tbsp citric acid
1/2 cup washing soda
1/2 cup epsom salts
1 tbsp ground soap
1 tbsp sodium percarbonate
15 drops lemon essential oil
15 drops eucalyptus essential oil

Witch hazel in a spritzer, to bind

Blend the citric acid, washing soda, epsom salts, ground soap, sodium percarbonate, and essential oils together in a food processor or coffee grinder (though this will require several batches) and transfer to a large, wide bowl.

Now it’s time to add just enough liquid to get the mixture to hold together in a mold. Not too much, though, or it will react in the bowl/mold, not in your toilet. That’s why we’re using a mister (it’ll spread the moisture better) and witch hazel (for some reason the reaction isn’t as vigorous when you use witch hazel, plus they dry faster, apparently).

So, spread your mixture out in your bowl so you have as much surface area as possible, and spritz. Then stir thoroughly. And repeat until you can grab a clump of the mixture and it will hold together when you pack it into a tablespoon and tap it out. I usually recommend the “firm squeeze” method for testing bath bombs, but for some reason these held together beautifully in moulds, but not in my hand.

Once the mixture will hold together, pack it into a mold of your choice (for these I like a tablespoon), and then tap it out onto a sheet of wax paper. Let dry overnight. Store in an airtight jar.

To use, drop one or two in your toilet. Once they’ve stopped fizzing, scrub away.

If you like more fizz, you can add more citric acid, but more acid will start counteract the effectiveness of the washing soda, which is a base.
