How To Use Borax, Washing Soda, Baking Soda & Others

We are on the very cusp of Spring (hooray!), and we always do some annual blogs around cleaning at this time. This winter was a particularly cold and tough one, but we made it! Now it’s time to clean out wardrobes, clean our spaces, get rid of any mold that grew while the house was cold, damp or closed up, and even clear our minds - to make space for the new season of growth and warmth.

We already have an  ebook (it’s free) available that has lots of tricks and tips about using various natural cleaners around the home, but here is a nice breakdown of natural cleaners that can really work wonders in your home.


Borax is our best selling cleaning agent. It is a naturally occurring mineral and has a variety of uses in and around the home. Although natural, borax is a strong cleaner and we advise wearing protective rubber gloves when working with it.

Borax has a number of uses, from being a general purpose cleaner, to killing mold, to softening laundry, and removing grease and stains.

To use as a mold killer, add 1/4 cup borax to 1 litre of hot water. Use this solution to scrub away and kill off mold on all surfaces. Make sure you leave it to dry on the surface for maximum anti-mold action.

Used in laundry, borax boosts the whitening power of bleaching agents, and because of its basic/alkaline nature, it can combat acidic stains such as those from tomato sauce, coffee, wine etc.

To use in the laundry, combine half a cup of borax with half a cup of washing soda in place of normal washing powder. If you want some bubbles for extra cleaning powder, add some  castile soap or a ¼ cup of  SCI powder to the mixture. You could also make this mixture in bulk for all your future uses.

Borax is also commonly used as an insecticide and pesticide. You can make a 10% solution and spray this on plants to kill mildew and harmful insects.

Washing Soda

I have clear childhood memories of my mom using washing soda to clean the laundry. I was (and still am) very sensitive to fragrances in traditional laundry soaps, so we found washing soda to be a great alternative as it is gentle and has no scent.

Washing soda acts as a softening agent and very gentle cleaner. So if you are finding your water a bit hard, traditional laundry softener a bit harsh or heavily fragranced, or just want a very simple yet effective laundry cleaning and softening solution, then give washing soda a try. Like borax, washing soda is also alkaline so can help with stains, but it has the additional property of ‘softening’. It binds to minerals in the water and lifts them away, allowing for better cleaning penetration.

You can add half a cup to your washing machine for a big load, or even combine it with borax as mentioned above for a powerful clean.

Baking Soda

Baking soda or bicarbonate of soda has got to be one of the most versatile natural cleaners out there, especially for the kitchen and bathroom.

Baking soda is well known for removing odours and burnt crusts off of pots and ovens. Sprinkle a generous amount of baking soda over the affected area so that it is completely covered, then moisten with some water and leave overnight. You should be able to wipe up the majority of it the next day.

Since baking soda is in the form of little crystals, it has a handy abrasive action which aids scrubbing and cleaning. Instead of using steel wool which can damage surfaces, rather use a paste made of baking soda and a little water to scrub with.

Baking soda is great at removing tea and coffee stains from mugs.

You can leave an open tub of baking soda in the fridge to absorb any odours.

Baking soda is also an alkaline, and it will react strongly with an acid such as vinegar. You can harness this reaction to clean toilets, drains and other areas of tough dirt and grime.

Combining With Citric Acid

Citric acid is a mild acid, and baking soda, borax and washing soda are all alkaline/bases. What this means is you can combine citric acid with any of the bases plus some water and it will create a fabulous, fizzing cleaning volcano as the acid and bases react with each other! If you’ve ever used a bath bomb and enjoyed the fizzy action, well this is the same thing (in fact bath bombs are created using citric acid and  epsom salts which is another alkaline powder); and you can use this fizzy action to blast away tough dirt, or clean toilets and drains with. Cleaning can be a science demonstration for the kids, how cool!

Complimentary Essential Oils

Adding  essential oils to these cleaners can enhance their powers as well as provide a natural fragrance if desired. 

Lemon essential oil is our number one cleaning oil. Citrus oils such as lemon and  orange are known to be cleansing, plus they leave a gorgeous fresh fragrance.

Lemongrass is also great, as is  tea treeeucalyptuslavenderpeppermint and orange. Add a few drops of your favourite essential oil to any of the mixtures listed above to boost their power.

Natural Cleaning Accessories

Spray bottles are a must-have. Get yourself a couple - they’re useful but not single use. You can keep them and refill them whenever needed.
