Instructions on How to Clean Cloudy Windows [In-Depth 4-Step Guide]

Windows that are more than a decade old may have cloudy or foggy panes. Nobody loves to see them but again cleaning them isn’t that easy like a new window. 

So, do you need to replace them? Obviously not. It’s a bit annoying to clean them, but you can do it.

How to clean cloudy windows?

Cleaning cloudy windows requires four steps. Prepare a solution of two cups of water, two cups of vinegar, and five drops of liquid dish soap. Then spray the mixture on the window. Wipe away the spread mixture with a dry microfiber cloth. Lastly, polish the glass with a microfiber towel too.

This explanation is just a teaser. For more to know, let’s read the article below!

What Triggers Cloudy Glass in Windows?

Your windows appear cloudy even after many cleanings and drying completely. Many factors can cause cloudy windows. Such as-

  • Condensation from humidity can build on the surface of a window due to temperature changes. It occurs between the interior and exterior of your home. It results in a cloudy appearance that requires more work to remove.
  • The specialists at US Inspect say; clouds appear on the glass when moisture condenses and evaporates.
  • Two panes, or pieces of glass, make up a double-pane window. This makes room between the glass panes. You may have a seal leak if there appears to be haze between the panes of your window. Unfortunately, replacing your windows is the only way to solve this problem.

Cleaning Cloudy Glass Windows: 4 Steps to Follow

A cloudy buildup can be easily removed as long as moisture deposits cause. Windows will be clear again in no time with just a few drops of soap, water, and vinegar! 

Required Materials

  • Water
  • Glass polishing compound
  • Three microfiber cloths
  • Spray bottle 
  • White vinegar
  • Liquid dish soap

Step-by-Step Instructions

When all the necessary supplies have been gathered, proceed to the directions. As long as you take your time and complete each step, you’ll be able to clean the entire surface in no time! Consider the following steps:

Step 1: Prepare a Cleaning Solution

First you need to prepare the solution. For that you’ll need two cups of water, two cups of vinegar, and five drops of liquid dish soap. Gather them and combine them together in a spray bottle. You can clean your pavers by using vinegar as well..

Step 2: Use the Solution on the Cloudy Windows

Spray the solution on the glass windows you made on your own in the first step. Try to spray the entire surface of the windows. It’ll be easier while cleaning the windows.

Step 3: Wipe Away the Solution from the Glass

Using a dry microfiber towel, remove the sprayed solution from the glass. The haze can be removed with large, circular movements as you wipe.

Step 4: Polish the Glass

Polishing the glass is an optional step that will give it a more transparent appearance. Make use of a microfiber cloth to polish the window. 

After you’ve polished one side of the window, go back and do the other. Use a second microfiber towel to wipe it clean.

The only alternative is to replace the glass windows if this cleaning method fails. Here I’ve added some glass windows recommendations to help you in that case. Check down below-


These glass windows are among the most effective available on the market. These will be useful to you. Also, they are reasonably priced.

What to Do in Difficult Situations?

The haze is likely between the glass panes if the above-mentioned cleaning method is failing. But you can still fix this difficult situation. How? We’re going to discuss it in the later section. 

This method is very useful when you’re unable to afford new windows. At that time you can try removing the seal and hand-washing each pane.

In this way, you can fix moisture and condensation between window panes. Just you need to maintain the fixation procedure.

Things to Consider Before Trying This Method

Be warned that this is a delicate operation that must be handled carefully. It can be difficult to remove the seal off the glass without breaking it.

It can be a challenge when it comes to repairing the window without letting in moisture. Calling in a window specialist is something we advise you to do.

The inner side of the glass can be drilled with small holes. If you wish to give cleaning the clouds without disassembling then give it a try. This will allow the contained moisture to be released into the air. The sun’s rays can dry them. 

It’s important to remember that this will permanently damage your glass. The holes can only be repaired with tape. 

Also, if you want to attach pictures on glass windows, you can’t go through the drilling procedure. The pictures then can’t be attached if your glasses have holes.

Required Materials

  • Safety glasses
  • ⅛-inch drill bit
  • Spray bottle with cold water
  • Drill

Step-by-Step Instructions

After gathering all of the essential supplies, follow the instructions below. Check out the following guidelines for professional success.

Step 1: Drill a Hole in the Corner of the Windowpane

Put on protective goggles or glasses if drilling throws glass particles into the air.

To prevent the drill bit from overheating, use a cold water spray. It’ll cool it as you drill a hole in the windowpane’s upper-right corner. 

Using this method, you can drill through the glass without splitting. Slow down and take your time; don’t put too much pressure on the glass.

Step 2: Drill a Second Hole in the Bottom Corner of the Windowpane

Drill another 1/8-inch hole diagonally from the first one. In the lowest left corner of the windowpane, do this. The drill bit should be positioned in the window’s upper-right corner, just as you did.

You can use drill bits like M7 or M42 for this drilling procedure. 

Step 3: Make Sure to Leave Ventilation Holes Open

Keep the gaps in the panes open to allow for airflow. To block the vents, use masking tape to cover the openings.

This is the end of my exposition. These procedures can help you complete your glass cleaning project. A professional can always be hired if you have problems.


Question: What cleaning products do professional window cleaners use?

Answer: Every time a professional cleaner is on the job, they utilize squeegees. Even they’re used in homes with stained and lacquered woodwork. When using a squeegee to clean inside windows, begin by squeezing off most of the soapy water.

Question: How should one go about cleaning their windows from outside?

Answer: In a small bucket, mix equal parts of water and vinegar. Using a clean microfiber mop or sponge, dip the sponge or cloth in the solution. Wash your external windows with a mop and water.

Question: How can cornstarch assist in window cleaning?

Answer: Granules of cornstarch are so fine for window cleaning. They are naturally abrasive on the atomic level. A tablespoon of vinegar and water mixture can be used to remove stubborn filth. You need zero effort at all.
