Can you put cloudy glasses in a dishwasher?
Only glass, and not crystal, should be washed in the dishwasher. As glasses are delicate and can break easily, it’s not advised that wine glasses go in the dishwasher. Instead, it’s best to wash them by hand. If you insist on learning how to fix cloudy glasses in a dishwasher, it’s advisable to set it at a short cycle, using a small amount of detergent.
Once the wash is finished, open the dishwasher door, to release the humidity and allow the glasses to air dry. Before putting any glasses on a wash cycle, always check that they’re dishwasher safe. If you want to know the best way to load a dishwasher, our guide tells you everything you need to know.
Maintenance for clean glasses
Once you’ve got all your cloudy glassware looking crystal clear again, regular cleaning will slow down the rate at which your glassware becomes dull. If you hand wash your glasses (the recommended method for cleaning wine glasses), add a few tablespoons of white vinegar to your washing up bowl. If you use a dishwasher, add vinegar to the rinse compartment (the place where you usually put your rinse aid).
While this won’t stop your glasses becoming clouded completely, it will reduce the amount of cloudiness. Moreover, it should take longer for that dullness to build up.
This means you should only need to give your glassware a thorough once over every month or so using the methods listed above.
Your top questions on how to clean cloudy glasses
How do you clean cloudy acrylic glasses?
First, wash the glasses in a solution of washing-up liquid and warm water, using a sponge to scrub the inside and outside of the acrylic glass. Then fill a large bowl or a sink with white vinegar, transferring the glasses into the liquid and making sure they are submerged. Leave them in the vinegar for ten minutes or until the cloudiness has gone. If it has worked, rinse off the glasses and dry them with a microfibre cloth. Otherwise, you can apply a thin coating of baking soda to the glasses, working it in with a damp sponge before rinsing clean and drying. All the cloudy residue should now be removed.
What is the milky film on glasses from the dishwasher?
The most common cause is hard water. Hard water contains a high level of calcium and magnesium ions, which can build up on the glass, coating it with a foggy-like film.
Also, hard water can reduce the cleaning power of dishwasher detergent. So, your glasses aren’t getting washed or rinsed correctly and are left with a layer of dirty, soapy water.
To combat the cloudiness, try adding vinegar to the rinse compartment (the place where you usually put your rinse aid). While this won’t stop your glasses becoming clouded completely, it will reduce the amount of cloudiness and it should take longer for that dullness to build up.
Can cloudy glassware be restored?
If your cloudy glasses have been caused by hard water, then there are several effective ways to restore them, most of which use homemade remedies. We’ve already discussed the power of using a water and vinegar solution. You can either spray on or soak your glasses in the solution, as well as use a cleaning paste of baking soda and vinegar.
But there are plenty of other ways to dissolve the cloudy film on your glasses. Try smearing petroleum jelly over the entire glass. Let the product stay on the glass for a few days, then wipe it off. Wash and dry the glassware as you regularly would.
Alternatively, filling your glass with warm water and dropping in a denture cleaning tablet will help dissolve any white streaky marks. Let it sit for ten minutes before rinsing out with warm water and drying off with a microfibre cloth or some kitchen roll.
