What is hard water? Do I have it?

Firstly, you may like to know what it is right?


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.  Depending on your location in the world & in your own country the water hardness can vary.  

Why it matters

Unfortunately, natural soap products are not as effective in hard water. They react with those minerals before they get a chance to do their job. You’re likely to end up with lots of soap scum. 

How to check

If you are on town water you could check with your local council or waterboard or you could use a test kit like for a pool.  But here is a simple method you can try at home 

          1. Fill a clear sealable bottle with water

          2. Add approx 10 drops of pure soap (like Castile soap)

          3. Close the lid & Shake it up baby!!

          4. Lots of suds & fairly clear water means soft water while Low in suds & murky water                      means hard water

How to handle hard water

Here are 2 simple & natural solutions for hard water.  

1) Tweak recipes to use more water softeners like washing soda, bicarbonate & Borax AND reduce the amount of soap used. 

2) When making products like hand wash/sprays that use water, use distilled instead of anything from your tap.

Hope this has helped someone, somewhere, somehow! 


Under Your Sink

Hi Rachel, thanks so much for your message and it was so lovely to actually chat with you on the phone in person about this :-)

As discussed, probably best to make laundry powder and dilute before you add to the machine if you want liquid.

Add some sodium percarbonate in your laundry powder to make it more heavy duty. Reduce the amount of soap and add some more water softeners like washing soda, borax or bicarb (or even a combo of them all).

Hope this gives you better results


Hi! Love your products and highly informative site! What about rain water/ tank water? We use it for the toilets and washing machine so im wondering if your laundry powder recipe will work OK? Presently I use a home made recipe of washing soda and sunlight soap (blitzed up and water added in my thermje to make a liquid coz apparently that’s what my machine prefers)but its not super effective. Is the supermarket washing soda OK or no good for us? Also is there a way to make your laundry powder liquid or would I have to dissolve it in water then pour into machine? Thanks so much!!
