This easy homemade glass cleaner leaves your windows streak-free and sparkling clean every time.

This DIY glass and window cleaner is one of my favorites because it’s so cost-effective, yet it works well. You don’t have to limit its use to windows, either. I use it on glass surfaces throughout my home, including the fronts of framed photos and my glass shower doors.

Window cleaning is never a fun task. It’s even more miserable when the glass cleaner you’re using leaves streaks. With 36 windows in our house, I need one that works quickly, cleans thoroughly, and doesn’t cost a lot. So, I set out to create a homemade window and glass cleaner that gets the job done right the first time. This is it!

Homemade Window and Glass Cleaner

The recipe below makes enough to fill a standard spray bottle. I don’t fill a bucket with glass cleaner to do my windows because getting dirt into the mixture leaves streaks. If you want to mix up a bucket of it, you’ll need to dump it out and make a new batch once it starts looking dingy.

Ingredients

  • 1 cup rubbing alcohol (“surgical spirits” in the UK)
  • 1 cup distilled white vinegar
  • 3 drops dishwashing liquid
  • Empty spray bottle
  • Squeegee and microfiber cloth

Directions:

  1. Combine the ingredients in a spray bottle and shake gently to mix.
  2. Spray the glass liberally then lightly scrub with a microfiber cloth to loosen any grime.
  3. Spray the glass a second time, then immediately press the squeegee’s rubber strip against the glass and pull it down the window in a smooth stroke.
  4. Wipe the squeegee blade with a dry cloth and repeat. Continue working until you’ve squeegeed the entire window, always wiping your blade between strokes.
  5. To dry any remaining drops on the corners and edges of your window, put a clean section of a dry microfiber cloth over your fingertip and quickly wipe.

Why THESE Ingredients?

Sharing homemade cleaner recipes always leads to questions about whether you can swap certain ingredients for others. In general, homemade cleaning recipes are written the way they are for a reason. Unlike cooking recipes, it’s not always easy to substitute ingredients in DIY cleaning products.

A Little Soap

If windows only got coated with dirt and pollen, a strong spray of water would get them clean. But windows also acquire a stubborn mess known as city grime. This is the product of smog and other airborne particles that coat hard surfaces. When water interacts with city grime, it can make the mess cling harder. That’s why you find dirt on your windows even after heavy rain.

Soap contains fatty substances that encapsulate greasy dirt particles, allowing them to be easily rinsed away. It helps separate city grime from glass. But the amount of soap matters. Don’t just squirt it in: too much will leave streaks on windows. In this window and glass cleaner recipe, we’re using dish soap — “washing up liquid,” for UK readers — because it has additional grease-fighting properties.

Plain Distilled White Vinegar

White vinegar cuts through grime on your window. It also helps dissolve the bonds between glass and things like bird droppings or dead bugs. It’s roughly 5% acidity and works fine in this recipe — there’s no need to buy a pricey “cleaning vinegar.”

Apple cider vinegar (ACV) is not a good substitute in this homemade glass cleaner. In fact, it’s rarely a good substitute in any homemade cleaning recipe. ACV contains pectin, which is a form of soluble fiber. On shiny surfaces like glass and windows, pectin causes streaks. On other surfaces, it leaves a residue that attracts pests. So, save the ACV for your salad dressing or bath.

Rubbing (Isopropyl) Alcohol

Isopropyl l has disinfecting properties that make it fantastic in this homemade floor cleaner recipe. Here it’s used to speed up evaporation just the right amount, which helps this homemade window and glass cleaner avoid leaving streaks.

Can I use a higher strength? Isopropyl comes in various strengths, ranging from 70% to 90%, depending on how much water has been added. The higher the percentage, the less water it contains, and the faster it will evaporate. So, while you can certainly use 90% in this recipe, you will need to work very quickly to avoid leaving streaks. I stick with 70% for that reason.

This is not the drinkable kind. Chemically, rubbing alcohol is isopropyl and is used for disinfection. That’s why, in the United States, it’s sold in the First Aid section of stores. In the UK, it’s known as “surgical spirits” and is available wherever you’d buy plasters or bandages.

Tips to Clean Windows and Glass

The Right Weather for Window Cleaning

It’s best to clean windows on an overcast, non-windy day. Glass that’s been warmed by the sun will cause the ingredients in this homemade glass cleaner to evaporate too quickly and leave streaks. (That’s true of any window cleaning product, by the way.) The wind will do the same.

The One-Way Trick

If you are cleaning both sides of a window, work the squeegee in opposite directions on each side. If you can’t open the window, try these steps to fix stuck windows before you begin. Using a top-to-bottom approach on the exterior and a left-to-right method on the interior will help you quickly identify which side has any streaks. (Though with this homemade glass cleaner recipe, that won’t happen.)

Scrub Then Squeegee

After applying glass cleaner, scrub the window and then use a squeegee to dry it quickly. I use this window cleaning tool that has scrubbing and squeegee sides and attaches to any universal extension pole to make cleaning tall windows much easier. Also, be sure to wash your scrubber and squeegee blade after you’ve finished cleaning your windows, and make sure they’re dry before you put them away.

  1. My favourite window cleaner is newspapers – they wipe completely clean and don’t leave any streaks. And they’re super cheap, or free if you have free newspapers in your area.

  2. I love the newspaper method, but microfiber towels are my new favorite. They are also streak free, and pick up EVERYTHING so they are also good for dusting. πŸ™‚

    Have you ever heard of/used a drop of jet dry in your window cleaning? I saw someone else (sorry, was just browsing the internet!) had a recipe using jet dry. I haven’t tried it, just wondering if you had.

    1. Katie Berry says:

      I’ve heard of people using that in window cleaner but can’t honestly say I’ve tried it. Sorry I couldn’t provide more info! πŸ™‚

  4. I’ve read about that too. I believe it said it works best on outside of windows and bathroom mirrors.

  5. Kelsey Hutchins says:

    Can I use apple cider vinegar in place of the white vinegar?

    1. Katie Berry says:

      Hi Kelsey,
      I wouldn’t recommend it. Apple cider vinegar contains pectin and is likely to leave streaks.

    Thank you for the help I needed. My Mother died in 1980 and I could not remember all the ingredients she used. Two were the alcohol and/or vinegar. My mother did the windows weekly and they always had a great clear shine when she finished caring for them.

    1. Katie Berry says:

      Hi Phyllis,
      I’m so glad you found the recipe again and hope your sparkling windows now bring back wonderful memories of your mom.

  7. learn something new today says:
