When the sun shines it may show up streaks and dirt on your windows. Even a little bit of dust and muck can affect how much light shines into your home, so get into the habit of cleaning your windows twice a year, inside and out – and more often if you live on a busy road.

What you need
Before you begin window cleaning, line up your tools:
- Window cleaning spray (either a natural or commercial cleaner); or a bucket of hot, soapy water (washing up liquid is best).
- A clean, soft cloth (an old T-shirt or cotton sheet is fine) or scrunched-up newspaper, for polishing windows and making them sparkle.
- A big sponge, to apply the soapy water.
- A squeegee, which cuts down the workload.
Prepare to clean
Remove knick-knacks and plants from the windowsill, take down blinds and tie back curtains.
Wash dirty windowsills, so dirt doesn’t transfer.
If you have secondary glazing, gently lower sliding windows and clean separately, using the same method as below.
Apply the cleaning product sparingly, either spraying on or washing the window with your hot, soapy water.
Wipe off excess water with the squeegee. Start at the top of the window and work downwards to the bottom, wiping the squeegee blade regularly to keep it clean. Some specialists recommend working in a reverse ‘S’ shape.
Remove any remaining water from the glass with a damp chamois (fine suede) or microfibre cloth, or with newspaper (see below), starting at the top of the window and working down in circles or small strokes.
Finally, dry the windowsill and any wooden struts that divide the panes of glass.

Natural cleaning methods
Vinegar removes film from glass surfaces and leaves windows streak-free. Use one part white vinegar to one part water. Add a squirt of washing-up liquid if windows are grubby.
If windows are really dirty or greasy, add two tablespoons of household ammonia to a gallon of water and rinse with a vinegar solution.
Lemon juice works much like vinegar to cut grease and polish glass surfaces – just mix one tablespoon of lemon juice into a litre of warm water.
Use toothpaste to polish out scratches in windows and glass surfaces. Work in with a soft cloth, then polish.

Tips for cleaning windows
Always be careful if you use a ladder to reach high windows. Wear sensible footwear, make sure the ladder is fully extended and secured, and ask a friend to hold it steady at the bottom. If you’re not comfortable with heights, bring in a professional window cleaner.
When buffing the clean, dry glass, use a pad of crumpled-up newspaper - the printers' ink gives your windows extra sparkle. Avoid getting the ink on UPVC frames, though, as it tends to mark.
Wash windows on a cloudy day. Direct sunlight may make it easier to see the dirt but it also dries windows too quickly, leaving streaks behind.
