Clean a window streak-free

Ninety percent of DIY streaks come from paper towels, direct sun, or the wrong cleaner. Here's the right method.

What you'll learn

  • Why paper towels and regular cleaner leave streaks
  • The squeegee fan-stroke technique that actually works
  • When to clean (not in direct sun)
  • The basic tool kit that replaces paper-towel-and-Windex forever

Step by step

  1. Make solution: 1 gallon of water + a few drops of Dawn dish soap (no more).
  2. Wet the glass evenly with a soft foam scrubber, top to bottom.
  3. Squeegee in a straight pull, edge-to-edge, overlapping each stroke by an inch.
  4. Wipe the squeegee blade on a microfiber between strokes.
  5. Detail the edges with a clean dry microfiber.
Safety note

If you clean windows in direct afternoon sun, the solution evaporates before you can squeegee. Do it in morning or overcast conditions only.
