Mix Coffee and Vinegar—Here’s Why Millions of Housewives Are Doing It

Every few years, a new household trick takes the internet by storm, and the latest one making waves in kitchens and cleaning groups is surprisingly simple: mixing coffee and vinegar. While it might sound odd at first, the combination isn’t meant for drinking—it's a clever, inexpensive, and eco-friendly cleaning hack that homeowners everywhere are falling in love with.

For decades, both coffee and vinegar have played starring roles in home maintenance. Vinegar is renowned for its natural acidity and cleaning power, while coffee grounds have long been used to deodorize, scrub, and absorb odors. But when these two everyday staples come together, they create a multi-purpose powerhouse that can tackle some of the toughest household problems.

1. A Natural Deodorizer for Trash Cans & Fridges

Old coffee grounds are already known for absorbing odors, but when mixed with a splash of vinegar, they become even more effective. The vinegar neutralizes bacteria that cause smells, while the coffee grounds trap lingering odors.

How to Use It:

• Mix used coffee grounds with 1–2 tablespoons of vinegar.

• Place the mixture in a small open container.

• Set it inside a fridge, trash can, or under the sink for 24–48 hours.

The result? A fresher space without chemical sprays.

2. A Powerful Scrub for Pots, Pans, and Stovetops

Caked-on grease and burnt spots on cookware can be notoriously stubborn. Coffee grounds act as a gentle abrasive, while vinegar cuts through grease and dissolves mineral buildup.

How to Use It:

• Combine 2 tablespoons of used coffee grounds with 2 tablespoons white vinegar to form a paste.

• Use a sponge or cloth to scrub cookware or stovetops.

• Rinse thoroughly.

It’s a natural alternative to harsh scouring powders.

3. A Garden Boost—Repel Pests Naturally

Gardeners have used both coffee and vinegar separately for years, but together they can help deter certain outdoor pests without resorting to chemicals.

How to Use It:

• Create a diluted mixture: 1 cup water + 1 tablespoon vinegar + 1 tablespoon coffee grounds.

• Spray around garden borders (not directly on plants).

This helps discourage ants and some small pests from crossing into garden beds.

4. Restore Shine to Glass and Stainless Steel

How to Use It:

• Make a polishing mix: 1 teaspoon fine coffee grounds + 1 tablespoon vinegar + 1 cup water.

• Apply with a microfiber cloth.

• Buff dry.

Perfect for sinks, faucets, and glass stovetops.
