Toilet Fizzy Bombs

Ingredients & Items:

  • 1 1/4 cup baking soda.
  • 1/2 cup citric acid.
  • Water in a spray bottle
  • Your choice of Essential Oil (Lemon or Peppermint is nice, approx 15-30 drops)
  • Silicone Mould (Shape of your choice)
  • Air tight Jar (to store in)

Mix the baking soda and citric acid together in a small bowl. Add the essential oils to the mixture, and then start gentley spraying while mixing the products. (The mixture may fizz a tiny bit, but that’s okay!) Test the mixture at this point by squeezing some in your hands. If it isn’t sticking together very well, spray a little more into your mixture and keep testing it until you can get it to form a good clump in your hand. (If you’re having issues, be sure to read the troubleshooting tips at the bottom of this post!)
Next, transfer the mixture into your Silicone mould of choice, and pack each cell down firmly. Allow the tabs to dry for several hours. When they’ve dried completely, gently remove them from the mold and they’re ready to use! Store unused tabs in an airtight container.

Troubleshooting Tips

If you’ve never made fizzy bombs like these before, there is a bit of a learning curve to getting them exactly right. Here are a few common issues people tend to run in to, and how to fix or avoid them.

If your tabs are really crumbly…

Use a bit more water next time. The mixture should resemble and feel like slightly wet sand. The mixture should also form a firm ball when you squeeze a bit of it in your hand.

If your tabs are expanding in their molds…

You’ve used too much water, and it’s causing the citric acid to start fizzing. The goal is to get the dry ingredients just wet enough that they’ll stick together, but not wet enough to start the citric acid reaction. It’s a fine line to walk, but just make sure to add the water a tiny bit at a time, and you should be fine.

If your tabs are taking a long time to dry…

It could be due to humidity. Try placing your tray toilet blocks in a cool or breezy space for them to dry out quicker.

Baking soda – A mildly abrasive cleaner and an excellent deodorizer.
Citric acid – Provides the “fizzy” effect, and also helps dissolve tough hard water stains.
Essential oils – Depending on selection you want them to eliminate germs and bacteria, and leave behind a fresh clean scent.

Simply drop one of these tablets into your toilet bowl, and let the fizzing action clean and freshen your toilet. Make sure the fizzy bombs fully fizz out before flushing.
