For many, cloudy glasses can be something of an embarrassment. Often people who find their glasses becoming cloudy over time, will either throw them away, or hide them at the back of a cupboard, only use them when no-one is looking. So, why does it happen? There are two main causes of cloudy glasses, and both tend to happen over time: one is due to hard water deposits, and the other is due to corrosion. These are completely different types of clouding, and require different precautions to prevent them from happening.
Hard Water Deposits
If you live in a hard water area, you may be faced with deposits gathering in your dishwasher. These deposits, such as lime-scale, can cling onto your glass and dishes, causing a cloudy appearance. Fortunately, whereas cloudiness is irreversible, this can be fixed, and easily prevented.
A regular, thorough clean of your dishwasher with Finish Dishwasher Cleaner will help to remove all the nasty detritus that can get left behind after a wash, like excess food, fat and lime-scale stored - before it can cling to your glasses. It’s advisable to clean your dishwasher every month, not only to prevent this, but to ensure that it’s performing at full efficiency, saving you time. Adding Finish Rinse Aid to your cycle, ensures that water droplets that form on surfaces are dispersed before they can evaporate and leave behind any of the lime-scale residue that they might have accumulated.
If you’re living in a soft water area then you’re particularly at risk of cloudiness, but it can happen anywhere. This can be caused by a number of factors, from heat exposure, poor glass quality, to overly long programme cycles. There are a number of ways to prolong the life of your glasses, and it’s important to get it right before clouding happens:
- When buying glasses, ensure they are dishwasher proof.
- Use Finish Shine and Protect to ensure your glasses are protected from cloudiness and stay shiny for longer.
- If you have one, check your water softener unit, as it may be on too high a setting.
- For more delicate glassware, wash at a low temperature, or on a glass washing setting. Dartington Crystal recommend Finish as the glassware detergent of choice, which should provide peace of mind when putting your favourite glasses in the washing machine.
- Once your dishwasher cycle has finished, open the dishwasher to allow excess steam to escape. More modern machines take care of this with internal fans. Let your glasses cool in the washing machine before removing them.
