    The most common thing to remove limescale in the kitchen is our daily condiment: vinegar.

    Generation of scale: The calcium bicarbonate and magnesium bicarbonate in the original dissolved water are decomposed in boiling water, releasing carbon dioxide, and precipitating into insoluble calcium carbonate and magnesium hydroxide, and sometimes magnesium carbonate is generated. This results in the formation of limescale.

    Vinegar contains acetic acid, which is the ability to react with substances in limescale

    Equation: 2CH3COOH+CaCO3=Ca(CH3COO)2+H2O+CO2

    2CH3COOH + Mg(OH)2=Mg（CH3COO)2 +2H2O

    Acetic acid: acetic acid, also known as acetic acid, glacial acetic acid, chemical formula CH COOH, is an organic monobasic acid, which is the source of sour taste and pungent odor in vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point and colorless crystals after solidification.

    Although acetic acid is a weak acid based on its ability to dissociate in aqueous solutions, acetic acid is corrosive, and its vapors have an irritating effect on the eyes and nose.

    The main component of vinegar CH3C00CH scale is calcium carbonate CaCO3 CH3COOH +CaCO3 = Ca(C2H2O2) +H2o +CO2

    The main component of scale is CACO3MG(OH)2 removal, and the main method of using strong acid to prepare weak acid and acid-base neutralization. The substance is mostly acetic acid, and the chemical formula is CH3COOH

    Chelating agents such as sodium hexametaphosphate, sodium tripolyphosphate, sodium citrate, EDTANA4 and so on can be considered.

    All of the above are stable salts that can chelate calcium carbonate in limescale and magnesium carbonate to become a water-soluble chelate.

    Organic reducing acids such as citric acid, malic acid, or non-oxidizing acids such as phosphoric acid can also be used.

    or the use of new polymers such as; Acrylate sodium salt chelating dispersant, high efficiency, high safety, no pollution, low dosage.
