Guide to Preventing Glassware from Becoming Cloudy

If you’ve cleaned glassware for a while, whether it’s through handwashing or by using a dishwasher, you might have noticed that no matter how hard you scrub with a dishwashing liquid, there would always be athat thin milky coat covering your glassware.

While this doesn’t exactly pose a direct health problem, it can be a little annoying to see white blotches on what would otherwise be pristine glassware, and there are two reasons why this is the case: hardwater deposits and etching.

Hard Water Deposits

One of the most common problems when it comes to cleaning glassware is the high mineral content in water. If this is the case for your kitchen tap water, you have what is known as “hard water”.

There are two problems with this: first, the mineral content can reduce the effectiveness of detergents used, which means you’ll need to use more detergent to deal with it.

Here’s what you can do to deal with hard water deposits on your glassware:

  • Check your water temperature.  Your tap water might be too cold, so if you have a water heater, try to use it when cleaning your glassware. If you don’t, try heating
  • Use a rinsing aid. Rinse aids can help you by reducing hte spotting and etching, but keep in mind that these are added with each dishwashing load.
  • Just add more detergent. Simply using more detergent might be effective at removing hard water deposits, but it might leave a soap film on your glassware if you’re not careful.

Etching

If vinegar, water temperature, or detergent isn’t enough to get rid of the staining on your glassware, the reason for it might be etching.

When you see this etching, this measns that the glass itself is being worn down through constant washing , the use of water that’s too soft, detergent that’s too harsh, or even too much pre-cleaning. The result is all kinds of tiny pits and scratches that can’t be removed.

Here’s what you can do to control the etching on your glassware:

  • Rinse gently. Most dishwashing detergents contain harsh alkaline salts neutralized by oils and food particules, but when all the residue is removed, the detergent will instead have a harsher effect on the glassware itself.
  • Try something else. Some detergents are harsher than others depending on how soft the water is. One way to minimize etching is to try a milder detergent that doesn’t use phosphates.
  • Use less detergent. If you have soft water coming out of your kitchen tap, you don’t need to use as much detergent or dishwashing soap. Try experimenting with varying amounts until you find just the right amount that will keep your glassware spot-free.
