330ml/11 fl oz Bicarbonate of Soda
125ml/4 fl oz Citric Acid
30-40 drops Essential Oil*
1-2 tbs Water
Ice cube trays (preferably those with a silicon base so they will pop out easily)
Mix the bicarbonate of Soda, Citric Acid and essential oils together. Add the water, starting off with 1 tablespoon. Only add the other tablespoon of water if needed. The mixture should resemble slightly damp sand. Press into the ice cube trays but do not overfill.
Now this is the fun bit - the mixture will fizz and you’ll need to press it down HARD! Keep pressing it down until settles and leave to dry for 1-2 hours. Remove from the trays and store in an airtight container. Use as required.
Sylvia says: “This is a great recipe to try out with children.. They’ll love the chemical reaction and can help to squash the mix into the trays. My bathroom smells fresh and clean with the added bonus of knowing that there are no toxic ingredients in the product”.
