What are the biggest mistakes people make with window cleaning?

The biggest mistakes in window cleaning are using the wrong materials, cleaning dirty glass with dirty tools, and underestimating how much access and detail work matter. At Binx, we often see people use paper towel, household sprays, or old rags that leave lint, haze, or streaking behind. Another mistake is ignoring frames, sills, or screens, which can quickly re-dirty freshly cleaned glass. Some people also attempt difficult ladder work without proper safety practices. Window cleaning seems simple until poor technique leaves worse results than before. Good results come from the right tools, clean solution, proper sequencing, and a careful finish around the edges.
