Can You Use Fairy Liquid to Wash Windows?

Yes, you can—and it actually works pretty well. While Fairy Liquid is best known for cutting through grease on dishes, its cleaning power makes it a surprisingly effective option for washing windows too.

According to the manufacturer, you can use a diluted solution of Fairy Liquid—mixed at the same concentration you’d use for washing dishes or mopping floors—to clean glass surfaces. This is especially helpful when dealing with stubborn grime or built-up dirt on exterior windows. The gentle yet effective formula lifts away grease and grime without damaging the glass.

Start by rinsing the window to remove loose dirt. Then, using a soft cloth or sponge, apply the diluted Fairy solution to the glass. Work it gently across the surface, paying extra attention to any areas with visible smearing or residue. Once you’ve wiped the entire pane, rinse it with clean water or go over it with a clean, damp cloth to remove any soapy film.

The key to a streak-free shine lies in the final step: drying. Use a separate, lint-free cloth—microfiber works best—to dry the glass thoroughly. This helps prevent water spots and smearing, leaving your windows sparkling and clear.

While commercial window cleaners are widely available, using Fairy Liquid is a practical, cost-effective alternative you might already have in your cupboard. Just remember: less is more. Overuse of soap can leave residue, so stick to a lightly diluted mix.

So yes—next time you’re tackling grimy windows, don’t overlook the little green bottle. With a bit of elbow grease and the right drying technique, you’ll be surprised at how well it performs.
