White bread-it’s not just for sandwiches anymore! Well actually, it never has been.

Maybe you saw your grandma take a slice of Wonderbread, roll it up, and use it to get a scuff mark off the wall or use it to polish the kitchen sink faucet. Perhaps you even saw your mom do the same when it came to soaking up oil or grease splatters. Your eyes weren’t deceiving you-using white bread to clean is a household cleaning hack that has been around for decades.

But how does it work? Because bread is porous and retains a pillowy texture, it can lift dirt or debris without scuffing surfaces or absorb messes easily.

Ready to try cleaning with a piece of bread around your house? Here are four ways to use bread to clean.

Absorb Grease Or Oil Spills

Even the greasiest messes are not match for a piece of white bread. Press a piece of bread onto a greasy spill on countertops or stovetops to soak up excess oil before wiping it clean with a cloth.

Remove Marks And Fingerprints From Walls

Pesky marks on the wall or dirty fingerprints are no match for a piece of bread. Take a slice of fresh white bread, remove the crust, roll it into a ball, and gently rub it over scuff marks, fingerprints, or dirt on painted walls. The soft texture can lift the dirt without damaging the paint.

Clean Delicate Surfaces

If you have an old oil painting, comic book, or even Bible page, that has collected dirt, dab a slice of white bread over the surface to lift the dirt off without harming the delicate surface.

Pick Up Broken Glass

Step aside Annie Lenox, there will be no walking on broken glass so long as bread is around. After using a broom to sweep up as much glass as possible, press a slice of bread over the area-the soft, porous texture traps the glass safely-to pick up tiny shards you might have missed.
