To clean your windows, you will need a bucket of warm water, a squeegee, a sponge, and some window cleaner. Start by mixing the window cleaner according to the instructions on the bottle. Dip the sponge into the solution and wash the windows, starting at the top and working your way down. Use the squeegee to remove the excess water and solution, wiping the blade clean after each pass. Repeat the process on the outside of the windows, being careful to avoid streaks. For particularly dirty windows, you may need to repeat the process a few times. Once you're finished, step back and admire your clean, clear windows!
