FAQ's - great stuff to know!
How do I use the dishwasher powder?
Simply add 1 tablespoon directly in the detergent compartment of your dishwasher, ensure your items are dishwasher safe & wash as per dishwasher instructions.
Whats better powder or tablets?
In all honesty I find the powder works better for me as it can spread throughout the dishes, dissolve more evenly & quicker. However the dishwasher tablets are convenient, still super effective & they make for great grout & oven cleaners. So in the end it really is a personal preference.
How long will it last?
Without having this lab qualified, the powder could last years if kept airtight & away from moisture. The dishwasher tablets however may start to crumble a bit over time & turn back into powder which you could still use.
What is hard water? Do I have it?
Well water is not just H2O, it also has a bunch of minerals like calcium, magnesium & limestone.The more minerals particles your water has, the harder it is. For more info check out this blog - What is hard water? Do I have it?
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.
What is Silicone Emulsion?
Made from a mixture of bicarb & sand which is then diluted to the white gel/glue like substance. It will help bind your DIY dishwasher tablets so they wont crumble as much.
The mixture heated up a bit when making tablets, 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?
We strongly suggest you do, especially with DIY options using soap. Using Vinegar as a rinse aid will neautralise any leftover soap scum & is all you need.
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, it may be hard water or the soap not reacting well, so decrease the amount of coconut soap & increase the amount of water softeners like Percarbonate & Washing soda in the mix. (You could use also try adding Borax or Bicarb as they are great water softeners)
