If your windows are still streaky after cleaning, you're probably making one of several common mistakes. Here's how professionals achieve perfect, crystal clear results every single time.
Why Your Windows Streak
Streaks are the number one frustration for people who clean their own windows. Understanding the causes helps you avoid them.
- Cleaning in direct sunlight causes the solution to dry too fast, leaving mineral residue
- Using paper towels or newspaper leaves tiny fibres on the glass surface
- Using too much cleaning product creates a soapy film that takes multiple wipes to remove
- A dirty squeegee blade drags old dirt across the clean glass
- Not cleaning frames and tracks first means dirty water drips down onto clean glass
The Professional 6 Step Method
This is the exact technique our window cleaning team uses on every job.
- Choose an overcast day or work on shaded windows to prevent the solution drying too fast
- Dust and wipe all frames, sills, and tracks first to remove loose dirt
- Apply cleaning solution with a scrubber using minimal suds. Less soap means less streaking
- Squeegee from top to bottom in one continuous, overlapping motion
- Wipe the squeegee blade clean after each stroke with a lint free cloth
- Detail the edges and corners with a dry microfibre cloth for a perfect finish
The Best DIY Cleaning Solution
Mix 2 cups of water with a quarter cup of white vinegar and half a teaspoon of dish soap. The key is minimal suds. Heavy suds are the most common cause of streaks on home cleaned windows.
Pro tip: Invest in a quality squeegee with a replaceable rubber blade. It makes more difference than any cleaning product. Replace the blade when it starts leaving lines.
