Washing your windows is the sort of annoying chore that you want to get right the first time. To make sure you only have to tackle this project once, note these common mistakes before you start spraying and wiping.
1. You choose a sunny day.
Do this job in the blazing sun and the cleaner will dry onto the hot windows before you get to wipe it off, leaving hard-to-remove streaks. Instead, choose a dry, cloudy day. But if the sun's out and you're itching to clean, start with the windows on the shady side of the house.
2. You don't dust the sills and sashes first.
Skip this step and any liquid that drips onto the window frames will create a muddy mess. Always vacuum the frame, sill, and sash first before tackling the glass.
3. You don't use enough window cleaner.
Don't be afraid to generously spritz your windows with cleaner especially if they are extra dirty. You need plenty of cleaner to dissolve and suspend the dirt so it can be completely wiped away. Skimp and you'll be seeing streaks!
4. You use newspaper to dry.
Some folks swear by this trick, but we've never had any luck using newspaper to dry windows. We find it messy and ineffective, and far prefer microfiber cloths. They are super absorbent, washable, and leave the glass shiny and streak-free.
5. You dry with a weak, linty paper towel.
If a paper towel is still your cloth of choice, be sure to choose one that's up to the task. There's nothing worse than drying with a towel that separates in two or leaves lots of lint on the glass.Tips from goodhousekeeping.com
