How to Get Streak-Free Windows (Pro Tips)

Streaks are the number-one frustration with window cleaning. You wipe, you buff, and the moment the sun hits the glass — there they are. Here's how professionals get a genuinely streak-free finish, and what you can borrow for your own windows.

It Starts With the Right Day

Never clean windows in direct sun. The heat dries your cleaning solution before you can finish, baking streaks right into the glass. An overcast day or shaded side of the house is ideal.

Skip the Paper Towels

Paper towels and old rags leave lint and push dirt around. Professionals use a squeegee with a sharp rubber blade for the glass and a clean microfiber cloth for edges and detailing.

Technique Matters Most

• Wash the whole pane first with a scrubber or sponge to loosen grime
• Pull the squeegee in a steady top-to-bottom or reverse-S motion
• Wipe the blade with a clean cloth after every stroke
• Detail the edges and corners with dry microfiber
• Buff out any remaining spots while the glass is still slightly damp

Don't Forget the Frame and Tracks

Even spotless glass looks unfinished if the tracks are full of debris and the frames are dusty. A complete clean includes wiping the frames and vacuuming or brushing out the tracks.

The Shortcut

All of this takes practice and the right tools. If you'd rather skip the learning curve, our crew does it every day and backs the result with a no-streak guarantee.
