How do I remove limescale from the tank and water tray?

Clean the inside of the tray with a little dish soap, warm water, and a sponge or brush.

For limescale deposits, use:

• Staedler Form cleaner & descaler,

• household descaler,

• or white vinegar.

Let it act, then scrub with a sponge or brush.

Rinse thoroughly with cold water.
