Make your own: Dishwasher Tablets

I’m such a sucker for zero waste recipes, and I’ve tried a huge amount in my time – some of them were total flops. So I promise you, I will only ever post recipes that work (for me at least). I came across this formula for dishwasher tablets recently, and as I had all the ingredients here, I thought I’d give them a go. They worked perfectly. You can buy cheaper – Wilko sell a cardboard box of 30 dishwasher tablets for £1. But, these really aren’t expensive and it’s very satisfying to make your own. I buy my bicarb and citric acid in cardboard boxes, so zero waste for those ingredients. Here’s how to do it. You’ll need:

  • 1 Cup of Bicarbonate of Soda
  • 1/4 Cup Citric Acid
  • 1 Tablespoon Dishwashing Liquid

Add the bicarbonate of soda and the citric acid to a large mixing bowl and stir together. Pour in the washing up liquid and mix all of the ingredients together thoroughly. I used my hands, but you could whisk it if you preferred.

Then, push lumps of the mixture into small silicone ice moulds. They will froth up a bit – this is normal (see image below). Just wait ten minutes or so and level them off with a knife. I put the excess into an empty mould space. This recipe made 24 tablets.

Leave them to harden for about four hours, or overnight. Then gently ease them out of the mould and store in an airtight jar. Place one tablet in your dishwasher compartment and you’re good to go!
