While you’re cleaning out your home and sorting unused items for the new year, it might actually be worth saving some old items to tackle chores or reuse for everyday storage.

One such thing? Old pillowcases. Using old pillowcases is not only cost-effective, but you’ll be surprised how useful they are for cleaning or DIY.

Below, we’ve tapped a professional cleaner to share all the best ways to repurpose old pillowcases.

Wipe dirty vents

If you haven’t cleaned your vents in a while, it might be time to wipe down those tight, dusty spaces before the new year hits, says Rhonda Wilson, a quality lead cleaner at FreshSpace Cleaning.

She recommends wrapping a pillowcase around a butter knife and lightly spritzing it with your favorite cleaner to get into those tough, tight spaces.

“Suddenly you have the perfect tool to get into those nooks and crannies,” says Wilson.

Turn them into dust bags

If you have a collection of treasured bags or everyday bags, consider storing them in an old pillowcase so they stay in good condition and dusty over time, says Wilson.

Wilson recommends putting your bags in a pillowcase and tying it shut so debris can’t get inside.

Dry your hair

If you’ve ever heard of the handy trick of drying your hair with a cotton T-shirt to prevent frizz and damage, you might want to try an old pillowcase, says Wilson.

“Cotton is smooth, won’t harshly damage your hair’s cuticle, and helps keep curls or waves intact,” says Wilson.

DIY Dog Bed Blanket

If you have dogs that like to lounge around, consider reusing an old pillowcase to create a cozy bed for them.

Wilson explains how you can fill a pillowcase with soft materials you already have at home, like a towel, an old pillow or even an extra blanket. Then, when everything is packed, tie or sew.

You’ll have the most comfortable space for them to relax during the day—and you won’t have to spend a fortune on a brand new dog bed, says Wilson.

Color filter strainers

Over time, the old paint can end up with dried pieces floating in it. The solution? Use old pillowcases to soak up the paint, so you can get on with those painting and DIY projects in the New Year.

Simply cover the opening of the paint can and secure it with a rubber band, says Wilson. When you spill paint, the pillowcase will act as a fine mesh strainer.
