Washing Soda (Natural Sodium Carbonate)

Washing soda is a strong alkaline cleaner that works by breaking down fats, oils, and stubborn build-up. It also softens hard water, allowing soaps and surfactants to clean more effectively instead of being blocked by minerals.

It’s one of those ingredients that makes everything else work better - especially in laundry powders, soaking solutions, and heavier cleaning jobs.

This ingredient is for you if you have:

• Greasy laundry, cloths, or kitchen build-up that doesn’t shift easily
• Hard water affecting how well your cleaners perform
• Too many single-purpose degreasers and boosters
• A preference for simple, effective, low-tox cleaning
  

What makes it useful

• Strong alkaline action for breaking down grease and grime
• Improves the performance of soaps and detergents
• Naturally softens hard water
• Septic-safe and biodegradable
• Breaks down naturally after use
• Replaces multiple specialised cleaners
• Highly concentrated and cost-effective
  

Ways people use it

• DIY laundry powders and boosters
• Soaking greasy workwear, tea towels, and cloths
• Cleaning ovens, rangehoods, and stovetops
• Degreasing sinks, drains, and bins
• General-purpose heavy-duty cleaning
  

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

• Avoid use on aluminium, sealed timber and delicate surfaces
• Always test first on coloured fabrics and surfaces
