What is bicarbonate of soda, its properties and history, and useful uses in the home
Sodium bicarbonate, also called sodium bicarbonate or simply bicarbonate, is a sodium salt of carbonic acid (NaHCO3). Its slightly alkaline pH (approx. 8,0–8,5) and its ability to neutralize acids explain its cleaning and deodorizing usefulness.
Among its most valued features are its versatility, low price, biodegradable nature, and lack of strong fragrances. It is water-soluble (and reacts with vinegar), making it easy to use in sprays, pastes, or cleaning solutions. One product, many uses, and fewer bottles in the cupboard.
- Versatile: cleaning of surfaces, joints, floors and sanitary ware; also on textiles and in the kitchen.
- Economical and biodegradableIt fits with sustainable cleaning routines.
- It does not scratch glass or mirrors: perfect for shower screens and chrome taps.
- Light abrasive: removes encrustations without damaging most washable surfaces.
Its history of domestic use goes back a long way: similar salts were exploited in salt lakes since ancient times and, with modern industrial processes, their production and quality were standardized. Over time, it went from the laboratory and industry to the kitchen and everyday cleaning.
And although we focus here on the bathroom, its range goes further: in the washing machine to boost detergent or lighten light-colored clothes; on carpets to treat stains by combining vinegar and baking soda; in the refrigerator as an odor absorber; and even in the vegetable garden and flower garden, where diluted in water it can help to repel ants or reduce certain fungi.

Safety tips and best practices
Before you begin, ventilate the bathroom well and wear gloves if you're going to scrub thoroughly or handle hot vinegar. Use cloths, sponges, and brushes designated exclusively for the bathroom to avoid mixing germs between rooms. Remove cans and accessories from surfaces, work from top to bottom, and rinse or dry as needed..
Avoid vinegar and abrasive products on delicate surfaces such as marble, some natural stones or sensitive woods; opt for gentler solutions in those cases. Test it in an inconspicuous corner when you are unsure of how a material will behave..
If you use effervescent mixtures (baking soda + vinegar), don't seal spray bottles with the active mixture tightly; prepare small amounts and use them immediately. And remember: don't mix vinegar with bleach or chlorine-based products. Safety and proper ventilation are part of effective cleaning.
To maintain a streak-free shine, microfiber drying at the end makes all the difference, especially on chrome and shower screens. That final step prevents veils and prolongs the anti-limescale effect.
You'll achieve a healthier and more environmentally friendly bathroom for your family, without sacrificing impeccable results. Plus, you won't be using harmful chemicals. But you'll still get the desired effect, and your bathroom will look sparkling clean!
