Before you begin

Citric acid is biodegradable and non-toxic for both humans and the environment. However, in its pure state this acid can irritate sensitive skin and any open sores, and it may even cause burns if in prolonged contact with mucous membranes. It must therefore be handled with caution. Wear gloves throughout the full process of making these toilet bombs, especially when mixing the preparation by hand. 

Citric acid is neutralized when combined with baking soda, so the final product is safe to handle! 

How to make toilet bombs?

Ingredients

• 68 g (75%) baking soda
• 15 g (17%) citric acid
• 4 g (4%) eucalyptus Castile soap
• 3 g (3%) lemon essential oil
• 10 to 20 drops of blue liquid colourant
• Spray bottle with demineralized water

Tools

• Stainless steel bowl
• A few spoons
• Scale, accurate to 0.1 g
• Pipette
• A few ramekins
• Pair of gloves
• One stainless steel mini bath bomb mold or three plastic mini bath bomb molds

Good to know!

• Commonly used for its whitening and purifying properties, lemon essential oil will control odours and leave your toilet bowl sparkling clean. 
• You can omit the lemon essential oil from this recipe, and it will still clean your toilet well and help keep it that way between cleanings. However, your DIY toilet bombs will no longer be disinfectant.
• Castile soap is a powerful multipurpose cleaner. 
• We advise against modifying the ingredients in this recipe, or your homemade fizzy toilet bombs may be less effective. 

Steps to follow

1. Prepare and disinfect your equipment and workspace.
2. Weigh all the ingredients in separate ramekins. 
3. Place the baking soda and the citric acid in a large stainless steel bowl. Mix to combine.
4. Add the Castile soap, essential oil, and liquid colourant to the powders and mix well.
5. Spritz five times with water, then mix well by hand, being sure to wear gloves. Spritz another five times with water and mix by hand again. Repeat until the mixture has a wet-sand texture. Don’t spritz more than five times at once, or the mixture may foam up.
6. Fill your bath bomb mold with the mixture, packing it down well. It should be compact.
   1. If you use a stainless steel, “tong-style” bath bomb mold, fill both sides as much as you can, then close the tongs tightly before delicately unmolding. Set your toilet bombs down on a piece of cardboard so that they don’t roll around and leave to dry for at least two hours before handling.
   2. If you use classic plastic molds, pack the mixture down well with your hands or a spoon. Wait at least four hours, ideally six to eight, before unmolding. You’ll know that your fizzy toilet bombs are ready when they unmold easily.

Use and conservation

When made in optimal sanitary conditions, these DIY toilet bombs will keep for three to six months. Store them in an airtight container in a dry place. 

To use, just place one fizzy bomb in the toilet bowl and allow it to sit for about 15 minutes. You can leave it overnight or throughout the day if you prefer. We recommend completing the job with a few swirls of a toilet brush, but you can also use one of these fizzy bombs to give your toilet a quick refresh between more thorough cleanings. Use as needed or once per week.
