Window cleaner (store bought or homemade from water, vinegar, and isopropyl alcohol) in a spray bottle
Murphy’s oil soap or other wood cleaner
cleaning cloths (I use diapers)
These are the instructions for cleaning the insides of windows. If you have the kind of windows that let you clean the outside from inside the house, these instructions will work for you.
First, pull up blinds and move curtains out of the way. (You can wash these at the same time if you have the energy and know how to do it.) Use the sponge and soapy water to wash the wood around the windows. (Squeeze the sponge out well so water won’t leak down on the walls.) Use the toothbrush where needed. Clean the sill as well.
Then, spray the window cleaner on one pane at a time. Use one cloth to wash the window, then use the drier cloth to get up all of the moisture. Windows won’t streak if you keep polishing until they’re dry. Work on one pane at a time, spraying, wiping, and drying.
If you’re washing the outside of the windows from the inside, do all of the insides before starting on the outside.
