Whether you’re cleaning a living room or another area of your home, cleaning windows is an important element of the task. For a sparkling, streak-free glass to complement your window treatment ideas, window experts at Hillarys recommend starting by removing these and cleaning curtains and cleaning blinds alongside your glass. While this is the first step, it will ultimately leave you with a complete finish. The experts then suggest making a homemade vinegar-based solution that will remove all dirt.

'Homemade solutions are great for cleaning windows,' they say. The experts suggest adding three tablespoons of vinegar into a bucket of warm water before mixing the solution. While cleaning with vinegar will emit a strong smell initially, the aroma will fade quickly.

'Always remember to wear rubber gloves when handling chemicals to prevent irritation and drying out your hands,' they add. 

Tempted to use this solution for cleaning mirrors, too? We advise against it, as this can penetrate a mirror’s backing.

After making the solution, Hillary's experts recommend tackling your window frames first. 'It's important you begin by cleaning your frames, so you don't drip any dirty water on to clean window panes,' they explain. Wiping down your frames with a wet sponge should remove most dirt. However, if they're especially dirty, you can also use a mild detergent.

After completing the frames, it's time to tackle the window panes. It is a good idea to fill your spray bottle with your vinegar solution for a seamless application over the glass. 

'Take a microfiber cloth and wipe in a Z-shaped motion to stop the smears and get every little,' they say. However, for more stubborn marks, you may need to dilute a mild detergent into the water.  

Use old newspapers to prevent streaks

'Old newspapers can be your holy grail when it comes to cleaning windows, especially at the end of your window cleaning process,' they share. This texture will remove any grease left over by your solution. However, this will also guarantee the streak-free finish you may desire. 

'Once cleaned, rub crumpled newspaper in circular motions to absorb any leftover cleaning flue and leave your window streak-free,' they explain.

If you're wondering how to clean windows from the outside, the process is similar to your interiors. However, instead of using a vinegar solution, cleaning expert Ray Brosnan suggests that washing up liquid and warm water will do the job. 

'The secret weapon, the scrim' – this is the cloth you want to use to wipe the edge of the windows. The Rendasun Window Cleaning Cloth is similar, and you can buy it on Amazon.

When It comes to the technique used to wash the windows, it's very similar to washing indoors; utilize the indoor cleaning method and be sure to cover the entire section of glass,' Ray adds. 

Now you know how to clean a window without streaks; you can enjoy a light-filled home, entirely taint-free.
