External window cleaning
Cleaning the exterior side of windows that don't unlatch and lower into a room is no easy task, especially for apartment dwellers ó unless you want to teeter dangerously on a window ledge.
Or you can pick up a magnetic window cleaner that won't risk life or limb.
Tools like these wash both sides of a window at once using microfiber cleaning cloths to wipe off any liquid cleaning product you decide to use. You can see how one works here.
Folks who own these gizmos say it takes some practice to get the tool to glide smoothly. For example, pushing it around too quickly while cleaning can disconnect the magnets.
