Most water spots left by lawn sprinklers, rainstorms, and car washing are basic alkaline mineral stains. To counteract bases, chemists use acids of complementary strength. For example, AQUA water spot remover contains an acid that reacts with typical mineral deposits. Moreover, it neutralises them and cleans them from paintwork, glass, and other polished exterior automotive surfaces. The simple chemistry effectively cleans mineral deposits without resorting to abrasive compounds, polishes, or even wet sanding steps that more severe spots require.
