Materials: window cleaning detergent (windowlin/ dish washing liquid), two clean clothes, two spray bottles, water
Pour a bit of detergent in the spray bottle and dilute it with clean water (approximately 1:4 ratio respectively). Spray the solution on the dirty window, take one cloth and use it to wipe off the dirt by scrubing gently repeatedly. After wiping the dirt off, use the other dry cloth to dry off the window.
Do this for each pane separately.
