Washing Soda (Natural Sodium Carbonate)

Washing soda is very effective, but it’s also more alkaline than bicarb — so it’s best used with intention and care.

• Not suitable for wool, silk or delicate fabrics
• Avoid use on aluminium, sealed timber and delicate surfaces
• Always test first on coloured fabrics and surfaces
• Wear gloves for extended contact
• Store in a cool, dry place away from moisture
• Keep out of reach of children and pets. Harmful if ingested

Used correctly, washing soda is a dependable, heavy-duty cleaner that earns its place in a simple green cleaning toolkit.

Hi, I'm Analisa the order packer. I pack everything fresh to order, and you have two options for how it arrives:

1. Apothecary Jar: It’s a wide-mouth jar made from recycled glass with a tinted amber look (not pure amber, but still charming). The lid even fits roughly a tablespoon, so it’s handy for scooping. Looks good on the bench and keeps your washing soda airtight and ready to go.

2. Earth Bag: A compostable option made from kraft paper with a plant-based inner lining. Great for transport and low waste, but not ideal for long-term storage. Just transfer it to a sealed container when it arrives - glass is best.

Whichever you choose, just keep it dry, sealed, and out of reach from little hands.
