Before You Start
Clear the window area of furniture and move plants or decorations away from the sill. Check the weather: a cool, overcast day helps prevent rapid drying and streaks. Wear protective gloves if you have sensitive skin and ensure children or pets are out of the area while cleaning. Avoid using abrasive pads or harsh solvents, which can scratch glass. Plan for multiple windows in a session to keep tools ready and avoid cross-contamination between cleaners.
Step-By-Step: How To Clean Greasy Windows Efficiently
- Dust the window frame and sills with a dry microfiber cloth to remove loose grit that could scratch the glass during cleaning.
- Spritz a small amount of ammonia-free glass cleaner for greasy windows onto a microfiber cloth for pre-cleaning greasy patches along edges and corners.
- Plate a second microfiber cloth or the microfiber cleaning cloths for windows glass cleaning to wipe the center of the glass, using circular motions to break up oil.
- Apply streak-free glass cleaner spray for windows directly to the window or to a clean microfiber pad, depending on your preference, for a final wipe.
- Use an extendable window squeegee with a microfiber pad to pull horizontal or vertical strokes from top to bottom, removing soapy residue and grease in one pass.
- Wipe the squeegee blade with a dry microfiber cloth after each stroke to prevent re-depositing grime.
- For stubborn greasy spots, reapply cleaner to the area and give it a second pass with the squeegee, starting at the top edge.
- Finish with a dry microfiber cloth or pad to buff the glass, removing any remaining streaks or moisture pockets.
- Inspect the window from different angles; if any streaks remain, repeat the final wipe with a fresh microfiber cloth.
- Repeat steps for each pane, turning the cloths or pads frequently to use clean, absorbent surfaces.
- Store cleaning tools in a dry place after use to prevent mold or mildew on cloths.
- For extra-clean windows, consider a final rinse with a clean water spray and a dry microfiber cloth on large panes.

|---|---|---|---|
| Streaks after cleaning | Drying too slowly or dirty cloths | Switch to a clean microfiber cloth and re-wipe with a drying motion | Use a lint-free pad and dry the surface completely |
