How to Clean Oil-Based Stains Off Pella Windows

The Pella Co., headquartered in Pella, Iowa, offers a wide range of windows and doors for the home. Oil-based stains on Pella windows can occur from grease splatter that reaches a kitchen window to sweaty palms or fingers creating marks on the glass. Oil-based stains require an acid to break down the oil and remove it from the window. After washing stains, remove the oily residue with white vinegar.

  1. Fill a spray bottle with one cup white vinegar and the rest with water. Fill a bucket with one tsp. liquid dish soap and water.

  2. Wash the oil-based stains from the Pella windows with the soapy water and a large sponge. Rinse the windows with clean water and the sponge. Dry the windows with a clean rag.

  3. Spray the windows generously with the vinegar solution. Dry the windows with a lint-free cloth, working from the top of the window down.

  4. Inspect the window for any streaks. Spray the window again if any streaks remain and wipe clean.
