Wash walls from bottom up or top down??

For decades I've read that when washing walls, start at the bottom,
and I've never understood it.

Now I have to wash a wall, and I need someone to explain it to me, to
convince me that that is the proper way.
Seems to me if you start at the bottom and get it clean, there will be
dirt running down the wall onto the clean part as soon as I get the
part above it wet. And I'll have to clean the bottom parts over and
over again.
Helpful advice appreciated.

I think you've got washing walls confused with shingling roofs.

No, he's right that that's what they say.

I've never understood it either. My solution has been to never wash
my walls. Anyone complains, I have a good reason.

Shingling roof: start at the bottom and work your way up.

Washing wall: start at the top.


When you take a shower, where do you start, top or bottom? ^_^

TDD"


Or wash a fire engine?
