This is a popular recipe and for good reason. It's quick to make, uses simple ingredients, and works just as well as many commercial alternatives.
The ingredients aren't just for dishwashing either. They can also be used for soaking tea towels, removing stains from mugs, cleaning pots and pans, and a range of other household cleaning tasks.
I prefer using powder because it disperses easily in the dishwasher and is simpler to make. Tablets however have their place and you can turn this recipe into dishwasher tablets with a few simple adjustments.
