If you notice that a hard-to-reach floor corner has collected some dust or dirt, or if you’re someone who has trouble stooping down to reach into hard-to-reach corners spray some cleaner into the corner, soak a couple of sheets of paper towel with hot water, and tuck the soaked towels into the corner that has a problem. Let it sit for a half hour or longer.
A half hour or more after you’ve left the soaked towel scooping it up with a dustpan should reveal a pretty much clean corner. Giving it another quick spray and a quick wipe with a clean paper towel may or may not be necessary. Using the dustpan for this finish-up wipe with a towel eliminates the need for having to lean too far down to reach.
