How to Remove Tempera Paint From Windows

Nick Davis

A fast-drying paint that contains egg and water, tempera paint is also known as poster paint. The paint is ideal for coloring posters, painting wooden objects and other items that require a fast-drying paint. Tempera paint dries to a matte finish and is less likely to fade over time.

Use vinegar to remove tempera paint from your windows.

Another use of tempera paint is to decorate residential and commercial doors, trim and windows. You can remove tempera paint from surfaces, including windows, without the need of a paint stripper or paint-removal tool.


Work in sections to remove the tempera paint if the design on the window is large or contains multiple layers of paint.

  1. Raise the window the tempera paint design is on and place a drop cloth or piece of plastic sheeting on the window's ledge. Lower the window.

  2. Mix 1 cup of white vinegar and 1 cup of warm water in a bucket. Wear latex gloves to keep your hands dry. Stir the mixture with a spoon.

  3. Dip a cloth or rag in the vinegar solution and wring out excess. Scrub the tempera paint design with the mixture-soaked cloth or rag.

  4. For heavy layers of tempera paint, blot the paint with the vinegar mixture, let the mixture sit for five minutes and then scrub.

  5. Re-dip the cloth or rag in the mixture. Wring out excess and continue scrubbing the paint until it is off of the window.

  6. Wet a clean cloth or rag with warm water from a sink. Wring out excess. Rinse the window with the damp cloth or rag. Dry the window with a clean cloth or rag.

  7. Remove the drop cloth or plastic sheeting.
