How to clean windows: 6 simple steps to a sparkling finish

Don’t worry, we’re here to help. Follow our six easy steps for exceptionally clean windows that will shine as much as the rest of your home.

It’s not just the panes of glass that need cleaning on your windows. Dust, pet hair and dirt can all end up finding a resting place on your window frames and need to be removed first.

Why? “If you dust these after you’ve cleaned the window panes you could undo all your hard work,” says Henry Paterson, cleaning expert at Housekeep.

For a thorough clean, open your windows, and dust or vacuum around the edges, frames and sills to remove any debris. The last thing you want is to fling open a newly cleaned window to let in the fresh air in only for exterior dirt to land on your gleaming glass.

Although the sun doesn’t contain much heat in the spring, remember that during the summer months that a sunny day isn’t the best one for cleaning windows. Although the bright light will show you where the streaks are, you’ll potentially end up creating even more of them. If the sun dries your preferred cleaning solution too quickly – you’ve guessed – it will cause streaks.

Either wait for a slightly cloudier day or until the evening when the sun emits less heat.

Although we often wonder what we did before the days of the microfibre cloth, they’re our go-to staple for window cleaning – as well as the rest of the home.

Even though newspaper or brown paper were traditionally touted as the best materials for creating a streak free finish, we’re not so convinced. Unless you’re a conscientious recycler, it’s also not the most ecological way to clean windows.

Instead, we prefer to use a damp microfibre cloth that’s been dipped into a solution of water and a drop of washing up liquid. Paterson also says to remember: “less is more when it comes to product. Using too much window cleaner can lead to streaky windows.”

Technique is key. “What’s most important when you start is to be thorough, getting right into the corners and edges,” says Paterson as these are often the dirtiest and dustiest edges. Windows can also come in all shapes and sizes, so it’s important to make sure that you don’t leave any of the surface untouched.

For more stubborn stains, try a solution of white water or cider vinegar with water. Usually made by combining equal parts of vinegar to water, we’d also add a spot of washing up liquid.

The eco-friendly experts at Purdy & Figg agree with this approach. “We love this method for glass cleaning because it involves natural products. Mix a few tablespoons of white vinegar with a couple of drops of dish soap in a trigger spray bottle. Then fill the bottle with warm water and shake the mixture so it is well mixed. Spray and wipe away with a microfibre cloth.”

If you’ve got large expanses of glass such as patio doors, or modern single paned windows, you have the option of using a squeegee – often the preferred tool of choice for professional window cleaners. Pick one with an extendable pole to save you having to stand on a ladder or stool.

A common technique with squeegees is to use a fan like method, working across the window horizontally, but a word of caution. Unless your technique is super slick, you’re likely to end up with more water puddles on the floor than when you use a cloth.

While it makes more sense to work across the window in horizontal stripes, it will also depend on the shape of your window frames. When there are curves involved, you will have no choice but to adopt a more circular method.

The ultimate goal is streak free, so buff until you have achieved a streak free vista that will be the envy of your guests.
