Pure citric acid for food-safe descaling of surfaces, objects, and machines

Limescale deposits don’t just look unsightly—they impair the function and life of electrical appliances and attract dirt and germs. Citric acid is highly effective for dissolving limescale quickly and regular use can help prevent the formation of new limescale deposits.

Use this versatile household remedy to descale kettles and washing machines or to care for kitchen and bathroom surfaces. HEITMANN Pure Citric Acid is highly efficient and can be dispensed as needed. The active ingredient is fully biodegradable.


Descale naturally with pure citric acid

Use the power of nature to descale objects, surfaces, and machines thoroughly and safely. Pure citric acid is fully biodegradable.

For a beautifully clean home
