Windows are difficult to keep clean; they’re often hard to reach and even a speck of dirt is clearly noticeable on their glass surfaces. Here’s a step-by-step guide to our proven window cleaning method.

Step 1

Check Weather

The best time to clean your windows is on a cloudy, dry day. If you work on them while the sun is shining, it will dry your cleaning solution too quickly, leaving streaks.

Step 2

Wash Exterior Window

Fill up half a bucket with warm water and add some washing-up liquid. Soak your sponge in the bucket and wipe the window from top to bottom and side to side thoroughly to remove as much dirt as possible.

Step 3

Squeegee Exterior Window

Swipe a window blade (squeegee) from top to bottom across the window to remove excess suds. Wipe the blade with a cloth after each stroke. Keep repeating this step until the glass is completely dry.

Step 4

Dry Exterior Window Frame


Use a cloth to wipe the window frame dry. This will stop water from dribbling down onto any panes below and will help create a tidy finished look.

Step 5

Window Vacuum (Optional)

An alternative to a window blade is an electric window vacuum. This tool is highly effective at cleaning windows and avoiding streaks.

Step 6

Spray Interior Window


For interior windows, start by spraying thoroughly with window cleaner.

Step 7

Polish Interior Window

Give the window a firm wipe with a cloth from top to bottom and side to side to get rid of all dirt.

Step 8

Remove Remaining Streaks

Remove Remaining Streaks

To remove any remaining streaks, simply scrumple up some black and white newspaper and rub the streak thoroughly. It should eventually disappear.
