Tips on how to clean windows

Clean your windows on a cloudy day rather than a sunny day

It is often when sunlight is streaming through our windows that we notice that they would benefit from being cleaned. However, the windows will dry too quickly, leaving streaks on the glass, so try and pick a cloudy day to tackle this task.

How often should I clean the outside of my uPVC patio windows?

Cleaning windows at least twice a year will make a real difference to the general brightness of your rooms.  It is surprising how dirty windows can get, especially if you live near a main road.

What equipment will be needed?

Washing up liquid in warm water works well to clean windows.  Apply this solution to the glass using a fibre cloth and then with a clean rubber squeegee, start at the top of the window and work downwards in a smooth motion, forming a reverse S pattern.  It’s handy to have a clean cloth to hand to regularly wipe the blade clean, so that dirt isn’t just being moved around. Wipe off any drops which might have landed on windowsills. Ensure paintwork and carpets are protected. Whilst you have a clean cloth with a warm soapy solution, it’s a good opportunity to wipe down the framework of your bifold door or patio door.

Environmentally friendly cleaning solutions

You can also make your own cleaning solution by adding two tablespoons of vinegar to a small bucket of warm water, instead of using washing up liquid.

Dry windows can be buffed clean using crumpled newspaper to give your glass extra sparkle.
