Why You Should Add Cornstarch to Your Window Cleaner—okay, let’s talk about that. Ever sprayed your windows until your arm felt like falling off… only to step back and see streaks everywhere? Makes me want to throw my rag out the darn window, honestly. And after I realized my glass was still gunky, I figured, “There’s gotta be a better way.” Well, turns out there is, and adding a bit of cornstarch to your window cleaner is the trick nobody tells you. It’s a total game-changer, just like finding out you can eat breakfast cookies and still call it healthy (yes, I’m sending you to my Deliciously Easy Breakfast Cookies because, trust me, you’ll want a snack after all this cleaning). And while we’re at it, if you need a pick-me-up before tackling dirty windows, my Blueberry Banana Oatmeal Smoothie is the fuel you didn’t know you needed.
Homemade Glass Cleaner with Alcohol
You don’t have to be a science whiz to whip up a powerful glass cleaner at home. Actually, all you need are a few things:
Rubbing alcohol– helps windows dry faster, so fewer streaks (bless).
White vinegar– cuts through grime like a hot knife through butter.
Just a scoop of cornstarch– trust me, it’s the secret genius here.
And of course, water.
Mix those up in a spray bottle, shake like you mean it (not too wild or you’ll spray your cat—learned that one the hard way). Spray, wipe, boom—windows so shiny, you’ll see your neighbor peeking back.

Benefits of Using Homemade Cleaners
Why bother with homemade stuff when the store sells twenty kinds? Here’s why:
You know exactly what you’re spraying—no mystery chemicals.
Way cheaper, honestly—save that cash for grilled potatoes at your next BBQ. (Here’s my go-to grilled potato recipe, by the way.)
Cornstarch leaves almost zero streaks, thanks to its weird ability to grab onto the tiniest particles.
Honestly, I’m still surprised major brands haven’t caught on. But hey, more streak-free glass for us homebodies!
Cleaning doesn’t need weird scary stuff in it. Seriously:
Cornstarch—plant-based, biodegradable, good for the planet (and your guilt).
Distilled white vinegar—classic, smells… well, interesting, but works.
Lemon juice is a fun swap too—extra zing, and your house smells fresher (unless you hate lemons).
You’ll feel better knowing you’re not adding weird junk to your space (or the air your dog breathes).
Common Mistakes to Avoid When Making Homemade Cleaners
Hey, I’ve messed this up so you don’t have to:
Don’t overdo the cornstarch—a teaspoon per bottle max, or your window will look like pancake batter.
Avoid using hot water; it cooks the cornstarch (seriously, it gets jelly-like).
Make small batches, shake often; stale cleaner is a no-go.
One more—don’t forget to rinse your microfiber cloth between windows unless you want streaks all over again.
Common Questions

Q: Will cornstarch scratch the glass? A: Nope! It’s super fine, won’t scratch your glass at all.
Q: Does the glass cleaner need alcohol? A: It’s not a must, but it dries everything quicker, so you see results faster (and less chance for streaks).
Q: What if my cleaner leaves a white film? A: That happens if you use too much cornstarch—less is more, promise!
Q: Can I use it on mirrors and shower doors? A: Oh, absolutely—the same mix works everywhere glass gets grimy.
