Understanding Limescale: What You Need to Know

What Is Limescale?

Limescale is the white substance that often appears in kettles, boilers, and water pipes. It forms when hard water—water rich in minerals like calcium and magnesium—is heated or evaporated.

Is Limescale Harmful?

Limescale and Your Home

  • Obstruction and oxidation of pipes
    Hard minerals form scale inside pipes, reducing water flow and damaging materials.

  • Visible traces on tapware
    White, chalky marks are commonly seen on bathroom and kitchen fixtures.

  • Dullness on surfaces
    Affects the shine of glassware, silverware, and tiles.

  • Washing machine wear
    Hard water can reduce the efficiency and lifespan of washing machines, increasing energy usage and wear on clothes.

  • Higher cleaning product usage
    People often buy more detergents and cleaners to compensate for hard water.

  • Shorter lifespan of electrical appliances
    Dishwashers, kettles, and similar appliances wear down faster due to mineral build-up.

Limescale and Your Health

  • Is drinking water with limescale harmful?
    No – in fact, minerals like calcium and magnesium are beneficial in small amounts. Most bottled mineral waters contain similar minerals.

  • Effects on hair and scalp
    Hard water can interfere with shampoo, leaving residue that may impact scalp health and hair growth.

  • Effects on skin
    May cause dryness, clogged pores, and irritation. Regular moisturising helps counteract these effects.
