Sodium percarbonate emerges as cheap, powerful cleaning agent

Sodium percarbonate, a white fine powder that releases hydrogen peroxide and washing soda when mixed with water, is highlighted as an inexpensive and effective household cleaner. It can remove stubborn stains, disinfect surfaces, whiten fabrics, and tackle mold and limescale without harmful chemicals.

The articles also note that common kitchen ingredients such as vinegar, citric acid, and lemon juice can dissolve mineral deposits on tiles and grout. A 1:1 solution of vinegar and water, or a paste of citric acid in warm water, is recommended for dissolving hard‑water scale, followed by rinsing and drying. Regular wiping and proper ventilation are advised to prevent future buildup.
