|本文=The white scale on a bathroom mirror is minerals in tap water, such as silicon and calcium, left behind when it dries. The calcium part can be removed with an acidic cleaner such as citric acid.
|なぜ=When the water evaporates the minerals stay behind and build up. The calcium in limescale dissolves in acid.
|ジャンル=生活・家事
|ファクト度=A
|ファクト度の根拠=Confirmed by an industry body, a housing-fixtures maker and a cleaner manufacturer; the claim that silica does not dissolve in acid could not be confirmed in primary or secondary sources and is left to the notes
|ネタ度=S
|ネタ度の根拠=The surprise that the scale is just tap water

|根拠3要約=Cleaner manufacturer (Seikatsu to Kagaku Sha): so-called limescale is the grime that acid removes
|根拠3格付け=一次
|補足=Scale high in silicon (silica) is said to resist acid and to need scraping off with an abrasive, but this could not be confirmed in manufacturer or research material. On mirrors with an anti-fouling coating an abrasive may remove the coating too, so check the mirror's care instructions. Never mix acidic cleaners with chlorine-based ones.
