Soda crystals are one of the best-kept secrets of professional eco-friendly cleaning. Known since the 19th century, they fell into disuse with the rise of synthetic chemistry in the 1950s, but are now making a strong comeback - and for good reason. On nearly all surfaces and household tasks, their effectiveness is comparable to, or even better than, commercial chemical products, at a tenth of the cost and with near-zero environmental impact. Here's why ÔME HOUSEKEEPING has made them a core part of its eco-friendly cleaning protocol in the Basque Country.
What are soda crystals?
Soda crystals (sodium carbonate Na²CO³) are a natural mineral compound, extracted from natural deposits or manufactured using the Solvay process. Their high pH (11-12) gives them powerful degreasing, stain-removing and deodorizing properties. They are 100% biodegradable, VOC-free, with no synthetic fragrance. Cost: €2 to €2.50/kg versus €8-15 for commercial chemical degreasers.
Soda crystals cost €2/kg and outperform chemical degreasers at €8-15/kg. It's the secret housekeepers have used for 100 years.
Objective comparison: effectiveness and impact
On greasy floors, soda crystals offer effectiveness comparable to commercial chemical degreasers. On heavily soiled surfaces, they even do better: their high pH dissolves grease deeply where some conventional products struggle. For laundry and textiles, they work just as effectively as traditional detergents. On the health side, the gap is clear: soda crystals emit no VOCs and don't irritate the respiratory tract, whereas conventional chemical products release VOCs, irritating fragrances and sometimes endocrine disruptors. Environmentally, soda crystals are fully biodegradable, unlike chemical products that pollute aquatic environments. Cost, finally, settles the debate: expect to spend €15 to €20 per year on soda crystals versus €150 to €300 for the equivalent in commercial chemical products.
