Day 7, Windows
Once you have cleaned the glass and mirrors, the next logical step is windows. Using the same concoction of lemon juice and warm water that you devised for the glass and mirrors, spray the windows and wipe clean with a lint-free cloth. Folding the cloth in fours creates four clean working surfaces, making window cleaning fast and simple.
Maintaining crystal-clear windows is just a matter of wiping them with a dry cloth once a week.
