They can gather paper towels, Windex, a step stool, and a trash bag. It is a great idea to wipe the windows inside in a different direction than the windows are wiped outside. This way, if there is a streak, you can know whether it is inside or out.

Remind them to put away all the tools and materials when they finish.
