If sap from a maple tree has been dripping onto one of the window panes on your home, remove it with the following steps. After you have removed the sap, clean the window with soapy water to remove dirt from the entire pane so that the glass is crystal clear. 


  • mineral spirits
  • cleaning cloth
  • plastic putty knife
  • mild detergent
  • warm water
  • bucket
  • mixing stick
  • sponge
  • squeegee
  • lint-free cloth

Remove The Sap

Pour some mineral spirits onto a sponge until it is damp. Use the sponge to apply the mineral spirits to the sap and wait for it to penetrate for several minutes. Move the sponge swiftly back and forth over the sap. As the hardened residue begins to loosen from the window pane, wedge a plastic putty knife under the sap to assist with removing it.

Add more mineral spirits as needed and wipe the glass surface until all signs of the sap have been eliminated. Wipe the window pane off with a wet sponge that has been dipped in water to remove the mineral spirits from the glass. 

Clean The Window Pane

Pour a cup or two of mild detergent into a bucket of warm water. Stir the contents in the bucket until they are sudsy. Apply the cleaning solution to the window with a clean sponge. Press down firmly on the sponge as you move it across the window pane. After all traces of dirt have been eliminated from the glass, remove soapy residue from the window's surface with plain water.

Use a squeegee to remove any water that remains on the window. Place the squeegee in one of the top corners of the window and pull it downward as you press down firmly on the handle. Move the squeegee over and continue removing water in the same manner. After you have covered the entire window with the squeegee, dry the window's casing with a lint-free cloth. 

Maintain The Window

Prevent sap from dripping onto the glass in the future by trimming the branches on the tree that are close to your home. If sap does, however, get onto the glass again, remove it as soon as you notice it to minimize the amount of time that it takes you to complete the necessary cleaning steps. Remove other dirt and debris from your home's windows a couple times each year so that each glass pane continues to look great and remains damage-free.
