The magical impact of white vinegar on limescale is no secret. You’ve heard it from your grandma. Just pour some vinegar into a dishwasher-safe bowl, place it in your appliance, load your glasses and use a normal cleaning programme, without any detergent, as the alkaline detergent will neutralize the acidity of the vinegar. For persistent stains, put your glasses into a bowl of warm water and vinegar. Let them soak for a while and then follow the steps above.

Lemon juice prevents limescale by leaving a fresh, pleasant scent in your dishwasher. What’s the secret ingredient? An acid that fights and dissolves limescale. It’s very simple: halve a lemon, place it in your cutlery basket and run the dishwasher, without any detergent. Sit back and let the lemon work its magic. Remove persistent stains by rubbing the lemon directly on the glass.

Hard water creates limescale, but it can be prevented. Find out more about the water quality in your area with our water hardness test strips. Then set the water softening unit accordingly – usually via the programme selector. Finally, add salt regularly and use the correct amount of rinse aid in every washing cycle.

Whether it’s a mellow red or a sparkling mineral water, nothing shows off your drink better than your crystal clear glasses. Our dishwashers take special care of them. But wash after wash, your glasses may become cloudy and one main reason is glass corrosion.

Glass corrosion is irreversible damage that washes away the surface of the glass. Poor glass quality, extremely soft water in the dishwasher – together with high temperatures and long programme cycles – are the main culprits. Read the following tips to have your glasses gleaming, in no time.

Put even your most valuable glasses in the dishwasher with complete peace of mind, thanks to the new glassZone*. Six integrated nozzles ensure a continuous but gentle water supply, enabling thorough cleaning without damaging sensitive materials. In addition, integrated soft anti-slip elements provide a secure hold, protecting against mechanical stress and preventing damage to glass rims.

^{* Please note that depending on the model, some cleaning programme and function names may vary from those on your appliance.}

When it comes to avoiding glass corrosion, the level of water hardness is an important factor. Soft water can dissolve mineral nutrients in the glass and cause ‘etching’ faster than hard water. Use our water hardness test strips to quickly and easily determine your water-hardness. This allows you to select the correct descaling setting for your dishwasher and protect your glasses from low pH levels.

To make sure that water drains optimally from your glasses for spotless drying results, your Siemens dishwasher adds rinse aid during the last rinse cycle. It also neutralizes soap residue and prevents deposits of limescale. Refill the rinse-aid dispenser regularly for perfectly sparkling results, in every wash.
