For many, cloudy glasses can be something of an embarrassment. Often people who find their glasses becoming cloudy over time will throw them away, hide them at the back of a cupboard, or 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. The first is due to hard water deposits, and the other is caused by 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 limescale, can cling onto your glass and dishes, causing a cloudy appearance. Fortunately, whereas corrosion is irreversible, this sort of clouding can be fixed, and easily prevented.
A regular, thorough clean of your dishwasher with Finish® Dual ActionTM Dishwasher Cleaner will help to remove all the nasty debris that can get left behind after a wash, like excess food, fat and lime-scale - 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® Jet Dry® 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 corrosion, another kind of glassware clouding, but it can happen anywhere. This can be caused by a number of factors, from heat exposure and poor glass quality to lengthy programme cycles. There are a number of ways to prolong the life of your glasses, and it’s important to get it right before the irreversible affects of corrosion occur:
• When buying glasses, ensure they are dishwasher safe.
• Use Finish® detergents to protect your glasses from corrosion and keep them shiny for longer.
• If you have a water softener unit, check to make sure it isn’t on too high of a setting,
• For more delicate glassware, wash at a low temperature, or on a glass washing setting.
• Once your dishwasher cycle has finished, open the dishwasher to allow excess steam to escape. Modern machines take care of this with internal fans. Allow your glasses to cool in the washing machine before removing them.
While water softness is largely dictated by your location, it’s not completely beyond your control. If you are unsure about whether you live in a hard or soft water area, this handy chart can help you find out.
