I love a recipe that turns “ugh, I should do that” into “wow, that took two minutes.” Homemade window cleaner is exactly that. You mix a few basic ingredients, spray, wipe, and suddenly your windows stop looking like a toddler practiced fingerprints for an art project.

This is not about being crunchy or perfect. It is about getting clean glass with fewer streaks and a cleaner that you can make on a weeknight while pasta water is coming to a boil. I am giving you two versions: a vinegar-based everyday mix and a higher-powered alcohol mix for greasy prints and mirror haze. Pick your fighter.

Why It Works

Streak-free dry down: The right ratio plus the right cloth helps prevent that cloudy film that makes you re-clean the same window three times.
Fast grease cutting: A small amount of dish soap (optional and tiny) helps lift oily fingerprints without turning your glass into a bubble bath.
Flexible for your home: Choose vinegar for daily cleaning or alcohol for a quicker-evaporating, polish-like finish.
Accessible ingredients: No specialty cleaners required, and you can scale the recipe up or down in seconds.

Storage Tips

Think of this like a pantry sauce. Make it, label it, and keep it where you will actually use it.

Container: Store in a clean spray bottle with a tight cap and working trigger.
Where: A cool cabinet away from heat and direct sun helps keep the spray bottle from warping and the mix smelling fresh.
How long: Use within 1 to 2 months for best results. These ingredients are generally stable, but the nozzle and bottle can get contaminated over time. If it starts smelling off, looks cloudy, or the bottle gets gunky, dump, rinse, and remix.
Label it: Especially if you have kids or multiple DIY sprays. Include the date mixed.
Safety note: Keep out of reach of kids and pets. Do not store near flames if using alcohol.

Common Questions

Why are my windows streaky even after cleaning?

Usually one of these: (1) you are using too much product, (2) the glass is hot from sun, (3) you are wiping with a linty towel, or (4) the window is actually still greasy. Use a microfiber cloth (skip fabric softener), clean in the shade, and do a final dry buff with a second cloth.

Can I use this on tinted windows?

For aftermarket window tint, the safest play is: avoid ammonia, use a gentle cleaner, and check your tint manufacturer guidance if you have it. If you are unsure, use the alcohol version as written, spray onto the cloth instead of the glass, and test an inconspicuous corner first.

Is vinegar safe for all glass?

It is generally safe for glass, but avoid using vinegar on natural stone around windows (marble, granite, travertine) and be careful around old or delicate finishes. Acids and stone are not friends.

Can I add essential oils?

You can add 2 to 4 drops for scent, but oils can leave a film if you overdo it. If you want truly streak-free, keep it simple.

What should I never mix into homemade window cleaner?

Never mix bleach with vinegar or ammonia. Also do not mix vinegar with hydrogen peroxide, and never mix chemicals “just to see.” If you are switching from a store-bought cleaner, rinse the bottle first so you are not accidentally creating a chemistry experiment.

Can I use this on plastic or acrylic?

Use caution. Alcohol can haze some plastics and acrylics. If you are cleaning a clear plastic guard, a framed poster cover, or anything you would describe as “acrylic,” spot test first and use the gentlest option.

I have always had a huge passion for the culinary arts, people, working as a team, and so on. I wanted to pursue my love for cooking initially at Virginia Commonwealth University with a culinary arts degree; however, I instead decided to apply myself and acquire more practical skills. My end goal is to eventually open my own restaurant or similar establishment.

Kitchen Essentials

Clean 16-ounce (2-cup) spray bottle
Measuring cup
Microfiber cloths (2 is ideal, one for cleaning and one for buffing)
Optional: funnel for neat pouring
Optional: small squeegee for big windows

The first time I made homemade window cleaner, it was not a wholesome Pinterest moment. It was me, squinting at my patio door, realizing the “fog” was actually months of fingerprints and dog nose art. I mixed a quick spray, wiped once, and immediately got that tiny hit of satisfaction you usually only get from a perfectly salted sauce. Clean glass is underrated. Also, it makes your whole kitchen feel like you have your life together, even if the sink says otherwise.
