Wondering where to buy soda crystals peroxide for cleaning? Here are my go-to places to shop for this green cleaning staple, including where to buy plastic-free soda crystals.

There are myriad uses for soda crystals around the home. From making your own natural laundry detergent to boosting the cleaning power of your regular detergent, and even cleaning blocked drains. Whatever your green cleaning needs, soda crystals can do it all.

If you are looking to give this natural cleaning powerhouse a go then you might be wondering just where you can buy some soda crystals to try it out for yourself. Well, wonder no more. I’ve got all the information you need!

Where To Buy Soda Crystals

The good news is that soda crystals can be picked up easily in the cleaning aisle of most large supermarkets and in many hardware shops. If you are struggling to find soda crystals in the shops near you, then here are my favourite places where you can buy soda crystals online:

  • Ethical Superstore
  • Big Green Smile
  • Amazon

Ethical Superstore

Dri-Pak is the only distributor of soda crystals in the UK. This means you can only buy Dri-Pak branded soda crystals in 1 kg bags. There’s no way to buy larger quantities in bulk.

You can pick up a twin pack of Dri-Pak soda crystals online at Ethical Superstore for just £3.66 (£3.66 per kg). Standard delivery costs £4.95 and is free when you spend over £50 at Ethical Superstore.

Big Green Smile

Dri-Pak soda crystals can also be bought online at Big Green Smile in 1 kg bags for £3.50 (£3.50 per kg). Big Green Smile has a minimum total order value of £29.95, with a delivery charge of £4.95. Orders over £50 are delivered free of charge.


Whilst I try to avoid Amazon on the grounds of tax avoidance, human rights issues, and environmental issues, I understand that not everyone is able to.

If Amazon is the most accessible option for you, then Amazon sells six packs of Dri-Pak soda crystals. This link is the cheapest I’ve been able to find soda crystals on the site. However, it’s worth bearing in mind, that in comparison, for the same amount of soda crystals at Ethical Superstore, with delivery included, buying from Ethical Superstore costs just very little more.

What About Plastic-Free Soda Crystals?

Dri-Pak soda crystals come in a plastic bag, to help stop them from going hard. If you are looking for a plastic-free alternative, then Big Green Smile sells Ecodoo soda crystals. These come in a plastic-free cardboard box. This French brand is the only brand I’ve found that makes fully plastic-free soda crystals.

The one downside is that the cost is considerably higher compared to buying Dri-Pak soda crystals. Ecodoo costs £3.45 for a 500 g box, which works out at £6.90 per kg, not including postage.

Can You Make Your Own Soda Crystals?

If you have bicarbonate of soda on hand – which is easier to buy in bulk – then you can also make your own soda crystals in the oven. I promise it’s not wizardry!

This method works by slowly heating the bicarbonate of soda in the oven. In doing so this releases the carbon dioxide and water molecules bound up in the bicarbonate of soda, leaving you with soda crystals.

To make soda crystals from bicarbonate of soda:

  1. Place around 250 g of bicarbonate of soda on a shallow baking tray, spreading it out to form an even layer.
  2. Bake in an oven heated to 200°C (400°F/gas mark 6) for around one hour.
  3. After an hour, stir the bicarbonate of soda and spread it back out to form an even layer.
  4. Pop the tray back in the oven for a further hour.
  5. After an hour, leave the tray to cool completely. It should have a coarser texture and a yellow tinge to it to indicate that the bicarbonate of soda has turned to soda crystals.
  6. Store in a labelled airtight container, out of the reach of children and pets.

Whether it is a cost-effective or energy-efficient solution, given the cost of energy right now, that’s for you to decide. Personally, I find it more cost-effective and convenient to buy soda crystals. I just wanted to share this method as I do get asked if you can make your own soda crystals with surprising frequency!

If you opt for using this method, then for maximum energy efficiency, be sure to fill the oven with as many trays of bicarbonate of soda as your oven will fit.
