How to Wash Glass Single Hung Windows

• 1). Brush off the window sill indoors and the top sill of the lower sash with a clean paint brush or a similar type of brush. Dust collects quickly on the sills.
  
  
• 2). Spray glass cleaner over the top and bottom panes.
  
  
• 3). Scrub the top pane and then the lower pane with a sponge or paper towels to break up grime. Wipe the panes with paper towels.
  
  
• 4). Spray the window panes again with the glass cleaner. Run a squeegee down each pane. The University of Nebraska Extension recommends wiping off the squeegee with a damp cloth or sponge after each pass. This helps the squeegee glide, rather than scrape, across the window.
  
  
• 5). Take your supplies outdoors, and clean the exterior side of the window. If you have a garden hose close by, gently rinse the windows with the hose and squeegee them. Otherwise clean the exterior just as you did the interior.
  
  

How to Wash Vinyl Single Hung Windows

• 1). Brush off the window sill and the frame around the vinyl window.
  
  
• 2). Spray a solution of dish detergent mixed with warm water (about 1 tsp. of detergent per gallon) on the vinyl windows, or use a commercial vinyl window cleaner.
  
  
• 3). Scrub the top pane and then the lower pane with a sponge to clean dirt from the vinyl. Rinse out the sponge if it gets too dirty.
  
  
• 4). Rinse the vinyl windows with clean water. Use a squeegee on the windows or towel-dry them to prevent streaking and spots.
  
  
• 5). Repeat the same cleaning process for the exterior side of the vinyl windows. Rinse them well with a hose before cleaning if one is available.
