Soda Crystals – The Facts!

Soda Crystals are one of the most versatile cleaning and laundry products on the market. They’re safe and economical, and have been used for hundreds of years, but some people are still confused about what they are and how they can be used. That’s why we’ve put together a few facts about our beloved Soda Crystals…


Soda Crystals also go by the name ‘Washing Soda’, or if you’d like to be a bit more scientific, ‘Hydrated Sodium Carbonate’.
Unfortunately they are sometimes confused with much stronger, corrosive Caustic Soda (Sodium Hydroxide) which are more aggressive and must be used with care when used around the home.


Soluble crystals used for a number of household and industrial uses, due to their alkaline properties. Around the home, they are used to soften water, dissolve grease and remove organic stains, including wine.


Soda Crystals are a simple, one ingredient product, with no other additives which makes them less likely to cause an allergic reaction such as perfumes or enzymes. They are made sustainably in the UK, are biodegradable, contain no phosphates, bleach, petrochemicals and are not tested on animals.


Soda Crystals are made and distributed by Dri-Pak, an independent family-run company based in Ilkeston, Derbyshire. They are available in all major supermarkets as well as many hardware stores and independent shops. More on availability.

    1. It’s an acid you want, like white vinegar or citric acid. The latter is marginally better as there’s no odour and it’s slightly more effective at removing limescale. Here’s a video.

    2. lime scale is removed by acid, soda crystals are the opposite, alkaline. Vinegar works well, but stinks. I prefer ctiric acid, which smells and comes in crystal form. Places which sell the Indian spice range Rajah sometimes have them, my turkish store has them, too.

  1. To remove odour from under the arms of my gym tops is it better to :
    1) Pre-soak with bicarbonate of soda then wash with soda crystals.
    2) Pre-soak with either product and wash.
    3) Or will just adding one or the other to the wash suffice.

  2. Can I use soda crystals to clean carpets , rubbed in dry to remove odours then vacuum up like you can with bicarbonate of soda ? Or just a liquid solution to clean urine stains and dirt ?

    1. They have water and very small quantitities of anti-caking agents. The ingredients are:
      Sodium Carbonate Decahydrate
      Magnesium Hydroxide

  3. Somewhere in my distant imagination, I believe there is a metal that soda crystals can’t be used on. I ruined a barbecue using it once and can’t remember what metal that was.

    1. Hi Anne – we haven’t heard this and it sounds dubious. From a legal point of view, we aren’t allowed to make recommendations from a personal care point of view. If you were to try it, make sure they don’t get in your eyes as the Soda crystals would irritate them.

    1. No. All colours will fade with repeat washing…but if you are using products that don’t have bleaching agent, optical brighteners etc, then the colours will be preserved for longer. If you are using less of your standard laundry detergent, there’s a possibility that you’ll be reducing the risk of fading.

    1. Soda Crystals are an alkali and vegetation doesn’t survive in such conditions; it’s why they can be used on drives and patios, but not lawns.

    1. Hi Brigitte – Soda Crystals are merely a mild alkali and would not be appealing for them to eat, or damaging to their skin.
