Ingredients and their measurements

Homemade dishwasher tablets are made by combining simple, natural ingredients like baking soda, citric acid, washing soda, salt, essential oils, and vinegar. The tablets are then left to dry before use. Here are the ingredients and their measurements for making dishwasher tablets:

  • 1 cup (325g) of bi-carb soda or bicarbonate of soda: This is the base ingredient that reacts with the citric acid to create a fizzing action, lifting grime and grease off your dishes.
  • 1/4 cup (60g) of citric acid: Citric acid has powerful cleansing properties and helps break down stains.
  • 1/2 cup (115g) of salt: Salt helps to soften the water and enhance the cleaning action of the other ingredients. You can use Celtic Sea Salt or Epsom salt (magnesium sulfate) to avoid disrupting soil health if you have an on-site greywater system.
  • 1 tablespoon (15ml) of plain white vinegar: Vinegar is a natural cleaner and can be added separately to the rinse aid compartment to remove residue and leave dishes sparkling.
  • 10 drops each of organic lemon and lemongrass essential oils: These add a fresh scent and extra cleaning power. You can also use eucalyptus essential oil for its deodorizing and disinfecting properties.

You will also need a large mixing bowl, a spoon for stirring, and a silicone-based ice cube tray or moulds for shaping the tablets.

Please note that you should wear rubber gloves while making the tablets to avoid skin irritation, and always keep them out of the reach of children and pets.

Mixing the ingredients

  • Bi-carb soda (also known as bicarbonate of soda or baking soda)
  • Citric acid
  • Washing soda
  • Salt (optional)

Once the dry ingredients are mixed, it's time to add the liquid components. Some recipes suggest adding lemon or lemongrass essential oils for their fresh scent and cleaning properties. Others recommend tea tree oil for its antimicrobial effects. You can also add lemon juice to introduce acidity and a pleasant aroma.

After adding the liquids, use a spoon or your hands to combine the ingredients thoroughly. The mixture should be well-incorporated and have a texture similar to wet sand. Be sure to wear rubber gloves during this process to avoid any skin irritation from the ingredients.

At this stage, you may also want to add a few drops of food colouring if you wish to give your dishwasher tablets a particular hue. This step is entirely optional and will not affect the tablets' performance.

Finally, it's important to work quickly as the mixture will begin to fizz and bubble due to the reaction between the bi-carb soda and citric acid. Spoon or press the mixture into your chosen moulds, ensuring they are well-packed and levelled. You can use silicone-based ice cube trays, ice cube moulds, or even a simple ice cube tray with small individual slots.

Leave the mixture to dry and harden. This typically takes around 4 hours or up to 24 hours, depending on the recipe and environmental conditions. Once the tablets have solidified, pop them out of the moulds, and they are ready for use or storage.

Shaping the tablets

Make sure to compress the mixture hard and pack it well. You can also use your fingers to shape the tablets, but be sure to wear rubber gloves to avoid skin irritation. It is important to ensure that the moulds are the right size for your dishwasher. If the tablets are too large, they can be placed in the cutlery drawer instead of the dishwasher tablet compartment.

After shaping the tablets, let them sit at room temperature for 4 hours or overnight until they have dried and hardened. This may take about 24 hours, depending on the recipe. Once they are solid, simply pop them out of the moulds, and they are ready to use!

Drying the tablets

Once you've mixed your ingredients and packed them into the moulds, it's time to dry your dishwasher tablets. This process will help your tablets harden and is essential to ensure they hold their shape and don't crumble when handled. Here are the steps to follow:

Leave the Tablets to Air-Dry

Let the tablets sit undisturbed at room temperature. This is the most common method for drying homemade dishwasher tablets. The drying time can vary depending on the recipe and environmental factors such as humidity. Some recipes suggest leaving the tablets to dry for about 4 hours, while others recommend leaving them overnight or for up to 24 hours. It is recommended to make these on a cool day with minimum humidity to optimise the drying process.

Remove Tablets from Moulds

After the allotted drying time, carefully remove the tablets from their moulds. Silicone moulds, such as ice cube trays, are a popular choice as they make it easier to pop out the tablets without breaking them. When removing the tablets, do it over your dishwasher or a bowl so that any loose particles don't go to waste.

Post-Drying Storage

After removing the tablets from the moulds, they should be completely dry and solid. Store your tablets in an airtight container in a cool, dry place. Ensure the container is sealed properly to prevent moisture absorption, which can affect the effectiveness of the tablets.

Using the Tablets

When you're ready to use your homemade dishwasher tablets, place one tablet into the dishwasher compartment and start the cycle as usual. For best results, it is recommended to use apple cider vinegar in the rinse aid compartment weekly to keep your dishwasher free of grease and grime.

Using and storing the tablets

Homemade dishwasher tablets are an effective alternative to commercial products, offering a more eco-friendly and cost-effective option. Once you've made your tablets, there are a few key things to keep in mind for their usage and storage.

Firstly, for usage, the general rule is to place one tablet into the dishwasher tablet compartment and then run a regular cycle. If your tablets are too big for the compartment, you can place them in the cutlery drawer. It is recommended to use one tablet per dishwasher load. Additionally, to enhance the cleaning and rinsing process, you can separately add white vinegar or apple cider vinegar to your dishwasher's rinse compartment. This natural cleaner helps remove residue and keeps your dishwasher free of grease and grime.

When storing your homemade dishwasher tablets, it is crucial to keep them in an airtight container. Glass jars or sealed containers are ideal for this purpose. Choose a cool, dry, and dark place to store them, ensuring they are out of reach of children and pets. This storage method prevents the tablets from absorbing moisture, which could compromise their effectiveness.

It is worth noting that the ingredients and measurements used in your tablets may vary depending on personal preferences and water type. Customization is one of the advantages of making your own dishwasher tablets, allowing you to add essential oils for a fresh scent and extra cleaning power. However, be cautious when adding vinegar directly to the tablet mixture, as it can cause the citric acid to react prematurely, reducing its effectiveness.

By following these usage and storage guidelines, you can ensure that your homemade dishwasher tablets deliver optimal cleaning performance while maintaining their quality and longevity.
