How to Use Homemade Dishwasher Detergent
Homemade dishwasher detergent can be used each time you run a dishwasher wash cycle. Here’s how to use it in powdered and tablet form.
Powdered Dishwasher Detergent
Use 1 to 2 tablespoons of powdered detergent for each load of dirty dishes. Place the powder into the dishwasher dispenser before you begin the cycle to prevent clumps that may not dissolve well.
If the mixture has hardened slightly, stirring well with a wooden spoon may soften it. However, if it has formed clumps, discard the batch. Keep in mind that the clumps will not dissolve correctly in the dishwasher.
Dishwasher Detergent Tablets
Place one homemade detergent tablet in the dishwasher detergent dispenser immediately before you run a wash cycle.
Tips to Make Dishwasher Detergent
- Make no more than 3 cups of a homemade dishwasher detergent because it does not contain the anti-caking ingredients of commercial brands and may not keep as well long term.
- Substitute lemon juice for the citric acid powder when making tablets if necessary.
- Choose small silicone molds or an ice cube tray to form dishwasher tablets.
- Select a mold that will hold about 1 tablespoon and create a tablet that will fit in the dishwasher detergent dispenser in your appliance.
