I did a lot of cleaning today. My mother has lived in this house for 20 years and.... well, she's never been big on housekeeping. I got on a ladder and got way up high. I worked for a couple of hours on high shelves, decorative fixtures, the fake ceiling rafters. There was a lot of old pet hair accumulated up there. I washed 2 walls also, and a couple of doorframes that she grabs onto when she walks through; over time that adds up to a lot of grime. I washed it all off.
Nothing looks any different. Things looked dirty when I started but now that they're clean it's not noticeable to anyone but me.
