Dishwasher Tablets

Instructions on how to make dishwasher tablets using natural ingredients


-   1/2 cup Washing Soda 

-   1/3 cup Coconut Soap Flakes 

-   1/4 cup Sodium Percarbonate 

-   5-7 tablespoons water 

Optional but recommended: 

20-25 drops Essential Oil


-   Measuring cups

-   Spoon

-   Bowl 

-   ice cube tray


Approx 25 tablets or 250g of powder


1.  Add all the dry ingredients into a bowl & mix well, taking care not to breathe in the raised dust  
2.  Add the water & essential oils spreading it through with the back of a spoon. It should resemble wet sand (not a cake mix) & hold together when presses between your fingers. 
3.  Add approx. 1/2 - 1 tablespoon of your mixture to each compartment in an ice cube tray & compress firmly. 
4.  Once tablets have set hard, pop out & store in an airtight container.  


It's very important to use a rinse aid solution like vinegar. It will neautralise any soap scum build up as well as remove hard water deposits, giving your glassware that shine.


What is Washing Soda?

It is mined the exact same way as Bicarb it's just more powerful. It is a powerful degreaser & general cleaner. You will find it nearly all commercial powder cleaning products.

What is Sodium Percarbonate?

It's a natural powerful Oxybleach made from Hydrogen Peroxide (a natural hospital grade disinfectant) and Washing Soda. It's the key ingredient in Napisan & stain removers.

What are Coconut Soap Flakes?

It is a pure hard soap made from only coconut oil, water & lye (caustic soda). It has been grated up into powder flakes, so they are easy to dissolve.

Do I have to make tablets or can I use the powder?

No, you don't have to make tablets, the powder is fine to use directly in the detergent compartment in your dishwasher. Use approx. 1 tablespoon per load.

The mixture heated up a bit, is this normal?

Yes, this is normal & nothing to worry about. This is science in action & occurs when you add the water.

Is this safe for septic tanks?

The ingredients are mild, safe & biodegradable which should not affect the bacteria in septic tanks like harsh chemicals can.

Do I need a rinse aid?

Yes, especially with DIY Dishwasher Tablets using soap. Using Vinegar as a rinse aid will neautralise any leftover soap scum. 

There is a white residue on my glasses, what happened?

This could be a few factors, but the first one to check is the rinse aid. You more than likely need to top up the vinegar solution. It could also be dirt in the pipes when rinsing, so give the dishwasher a clean. Finally, you may need to increase the proportion of Sodium Percarbonate in the mix.
