Es un ejemplo de qu\u00edmica escondida en la limpieza de casa.<\/p>\n<h3>El sarro del grifo es, en realidad, una piedra<\/h3>\n<p>Esas manchas blancas se forman cuando los minerales del agua del grifo, como el calcio, se endurecen y se quedan pegados. M\u00e1s que suciedad, es piedra, y se dice que su componente principal es el carbonato de calcio.<\/p>\n<p>El carbonato de calcio est\u00e1 en cosas muy cotidianas, como la tiza, las c\u00e1scaras de huevo y las conchas marinas. Las estalactitas de las cuevas y el m\u00e1rmol tambi\u00e9n son de la misma familia. As\u00ed que el sarro de tu grifo es, por decirlo as\u00ed, una peque\u00f1a estalactita que ha ido creciendo despacito a su alrededor.<\/p>\n<h3>\u00bfQu\u00e9 pasa si le echo Sanp\u014dru?<\/h3>\n<p>Prob\u00e9 a echar Sanp\u014dru, un limpiador de inodoros muy popular en Jap\u00f3n, sobre una mancha de sarro que hab\u00eda junto al grifo de mi laboratorio.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-68838 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/08\/%E3%82%B9%E3%82%AF%E3%83%AA%E3%83%BC%E3%83%B3%E3%82%B7%E3%83%A7%E3%83%83%E3%83%88-2026-10-25-5.19.33.jpeg\" sizes=\"auto, (max-width: 95px) 100vw, 95px\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/08\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-10-25-5.19.33.jpeg 474w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/08\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-10-25-5.19.33-131x300.jpeg 131w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/08\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-10-25-5.19.33-448x1024.jpeg 448w\" alt=\"\" width=\"95\" height=\"217\" \/><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/link.amazon\/B0dHx1Qyh\">Sanp\u014dru<\/a><\/p>\n<p>La reacci\u00f3n fue inmediata y la mancha desapareci\u00f3 de un modo tan satisfactorio que no me resisto a ense\u00f1\u00e1rtelo. \u00c9chale un vistazo al v\u00eddeo:<\/p>\n<p><iframe loading=\"lazy\" title=\"\u86c7\u53e3\u306e\u767d\u3044\u6c5a\u308c\u306e\u6b63\u4f53\u300c\u77f3\u300d\u306b\u30b5\u30f3\u30dd\u30fc\u30eb\u30675\u5206\u3001\u6c34\u57a2\u304c\u6d88\u3048\u305f\uff01\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/FhPbnPZOuJY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-69425 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.55.jpeg\" alt=\"\" width=\"612\" height=\"498\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.55.jpeg 1406w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.55-300x244.jpeg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.55-1024x833.jpeg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.55-768x625.jpeg 768w\" sizes=\"auto, (max-width: 612px) 100vw, 612px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-69426 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27.jpeg\" alt=\"\" width=\"609\" height=\"451\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27.jpeg 1632w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27-300x222.jpeg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27-1024x758.jpeg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27-768x568.jpeg 768w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2026\/11\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2026-11-11-4.22.27-1536x1137.jpeg 1536w\" sizes=\"auto, (max-width: 609px) 100vw, 609px\" \/><\/p>\n<h3>\u00bfPor qu\u00e9 se va la mancha?
