How to Clean, Remove and Prevent Cloudy Glass Efficiently
As a restaurant or bar owner, you can’t take the risk of cloudy glasses. Imagine a situation in which the kitchen operator opens the dishwasher and sees foggy glasses. Or even worse, a regular customer that gets a hazy glass of wine.
So, you wonder, why is this happening? How can I solve this cloudy trouble? That’s the most often question that we got from our clients and here’s the bunch of explanations and solutions that will instantly affect on your restaurant or bar business.
To figure out what occurs onto the glass, it is essential to know what type of material glassware is. It may look like a solid substance to the touch, but it is actually a non-crystal solid, a liquid that was supercooled and is now somewhere between a liquid and a solid. Therefore, a liquid can seep into the glass through microfractures, giving the surface a foggy looking.
What is Cloudy Glass?
A cloudy or sick glass is an industry term describing glass that has calcium deposits, which produces a light, hazy appearance in glassware. Often, cloudiness is caused by permanent contact with hard water the water that contains calcium, lime, or other minerals and this cloudiness can be challenging to get rid of.
Of course, glassware is made to be used, but you can achieve great cloudy glass prevention with thoroughly rinsing the item after each use and hand-dry with a microfiber cloth.
If the long time of usage has ruined the image of glassware, however, there may be a remedy. Over the time, DIYers and cleaning experts have presented many household items that they have found cleaned from simplest to heaviest hard water stains.
Why Cloudiness Occurs in the Glass?
There are 4 main reasons why glasses look sick after dishwashing.
First reason is hard-water minerals like calcium, lime, and other minerals which are making a film build-up or dishwasher continuously etched the glass.
The second factor is etching that happens when the parts of glass are worn down because of regular use during washing or handling.
Third reason is the type of detergent that you apply and how efficient that dishwasher detergent really certainly has an effect on how clean glasses come from a machine.
The fourth factor is how quality and effective commercial dishwasher is.
How to Determine Glass Cloudiness
When the dishwasher works, things get hot inside. Without hard-water minerals to act on, and little food excess to occupy them, the cleaning phosphates in dishwashing detergent turn into nightmares for glasses.
So, at the end of the cycle, you get foggy glassware that no amount of cleaning solution can take away.
To define either you’re dealing with simple water stains on glasses, etching, or hard water deposits, pour a bit of vinegar onto the foggy glasses. Rub it around with a finger. Drain the vinegar and let it dry. If the rubbed area dries clear, you can clean these water stains on glasses. If there’s no change, however, glassware has been irreversibly etched, and the damage is irreparable.
Therefore, our team of experts and technicians made a list of 3 methods on how to clean cloudy glass.
If you have problems with hard-water that could be coming out of a tap, you’ll need 3 household cleaning items to get rid of foggy glassware such as:
- white vinegar,
- baking soda,
- microfiber cloth.
Only you need to do, is to soak the glasses in white vinegar for 5 minutes. Since vinegar is acetic, it’ll dissolve the minerals leftover in a glass. If some tough spots still persist, smoothly rub them off with a little baking soda. Then, just rinse glass by hand and dry them with a microfiber cloth or a lint-free towel before drinking out of them again. This is a child’s play way on how to clean glasses with vinegar.
Citric Acid Crystal Treatment
This is a simple method, just fill dishwasher’s detergent dispenser with citric acid crystals that you can find in pharmacies or hardware stores and run the glasses through a regular wash, without using any detergent. The citric acid runs as a limescale remover and descales the dishwasher at the same time, so now you know how to remove cloudy glasses in dishwasher.
Also, you can try to wash glasses by hand. Apply warm water and washing-up liquid, then rinse in clean water. Dry with a soft linen cloth. Afterward, use the commercial dishwasher, make sure it is always topped up with adequate salt and rinse aid, and remove glasses before the drying cycle starts, as high temperatures accelerate the etching process. As an alternative, purchase cheap glassware that you won’t mind replacing every couple of years.
What you’ll need is basic white toothpaste. Put some toothpaste onto glass, and then use an old clean toothbrush to scrub away at the toothpaste, spreading it all across the glass.
As a very mild abrasive, toothpaste gently removes that foggy film while not doing any to ruin glassware, so you can even use this method technique for delicate items. The cons of this cleaning cloudy glass operation are that it does take a little bit of elbow grease.
Hard water is called hard because of the high amount of magnesium and calcium it contains. Hard water can deposit these minerals onto anything inside dishwasher. Even the best dishwashing detergents will need a much time dissolving grime and dirt, and truly rinsing it all away when there is a high amount of limescale present.
If glassware is cloudy in because of hard water deposits, you should act instantly. The longer you wait to solve this foamy issue, the more challenging the deposits will be to rid of, and the problem will be bigger and grow more the longer you hesitate.
Managing of Hard Water Deposits on Glassware
If you notice hard water on the glassware, there are a few tips you can apply:
- Add more detergent; More detergent may be more effective at removing hard water deposits from glasses. Simultaneously, applying too much soap may leave a soapy layer on the glassware, so try with different amounts to discover the right balance.
- Apply a rinse aid; Rinse aids come in liquid and solid forms. They help reduce etching and spotting by breaking the connection between water and the glassware.
- Test water temperature; Run the water at the kitchen sink for 2 minutes. Put a thermometer in a glass and run water into the glass to measure incoming water temp. Many dish detergent producers recommend a temperature of 130°, but rather than turning up hot water heater uselessly high, use the high-temp setting on dishwasher to heat the water no higher than 140°. If water heater is far from the kitchen and it takes a while for the hot water to arrive, run the tap for a minute until the water is warm, then turn on the dishwasher.
This typically occurs in areas with soft water and when poor-quality dishwashers are used. The phosphates in dishwasher detergent and the higher temperature drying cycles are the main factors for creating of cloudy drinking glasses. The useful way to prevent, or delay, the cloudiness from occurring would be to handwash glasses.
If you use the dishwasher, the best recommendation is to remove glasses from the dishwasher after the wash cycle, rinse them, and allow them air dry. Or may be looking at replacing glasses every few months or so.
Glassware Etching Maintenance
There are a few things on how to maintain etching on glassware:
- Avoid heavy rinsing or prewashing: Up-to-date dishwashing detergents contain coarse alkaline salts that are neutralized by food wastes and oils on the glass. If you remove all food leftovers from dishes before loading the dishwasher, the detergent has nothing to compensate it, occurring in a rougher effect on the glassware.
- Apply small amount of detergent: It’s great solution if you have soft water. Fewer detergent is required with soft water, so try with various quantities of detergent as far as you get enough to make the dishes clean.
- Try a different detergent: Some detergents cause etching more than others, depending on the softness of the water and other factors. Try a milder detergent without phosphates or with a lower pH number.
