Are you putting out incandescent or LED Christmas lights? Yes, incandescent lights are less expensive, but they don’t last as long as LED lights that cost more and last longer. No matter which you choose, either one will look brighter reflected in clean windows. Accumulated grime, water stains, cobwebs, and other dirty stuff will dim your joyous display.
Just think about your front windows, all sparkly clean to showcase your Christmas tree. Not only will neighbors and passersby enjoy its dazzle, you’ll enjoy seeing your lawn decorations and those of your neighbors.
Hope your holidays are bright!
