Purdy & Figg Loo Bombs are a gentle yet effective natural cleaner for the loo, working to whiten, disinfect and prevent limescale build-up. Follow this simple step-by-step guide from Charlotte and Purdy to make your own Loo Bombs at home - they can be made in bulk and stored in an airtight container for whenever you need them!  

The recipe below makes 6-10 loo bombs. 


  • Teacup of Bicarbonate of Soda 
  • ¼ teacup of Citric Acid  
  • 30 drops of Essential Oil blend
  • Witch Hazel (up to 1.5tbsps)


  1. Measure out Bicarbonate of Soda into a mixing bowl
  2. Add Citric Acid and stir well with a metal spoon
  3. Add the Essential Oils to the Witch Hazel in a beaker and stir with spatula
  4. Add liquid gradually, ideally using a spray bottle, mixing with your hands (wear gloves if you have broken skin and/or allergies)
  5. Pause to mix well between each spray/pump to allow mixture to absorb the liquid without creating a reaction
  6. The mixture is ready when it clumps loosely in your fist
  7. Transfer to individual moulds/cake cases (approx 2 inch diameter)
  8. Allow to harden for at least 3 hours before using
  9. Store in an airtight container and keep for up to six months

How to Use:

  1. Drop one ‘bomb’ into the loo
  2. Leave for 30 minutes or overnight, then scrub with loo brush if necessary
  3. Repeat once a week to maintain, every day for a week for tougher stains
