So nesting is starting to kick in (I think) and there are SOOOO many things around this house that are bugging me.

I need to clean down all the walls, and I need to do it now lol however I don't have much energy so I want to get it right first time.

What are your tried and true ways of cleaning the walls without streak marks appearing afterwards.

Do I need to do from top to bottom or can I just do the lower half where the kids reach up too?

Thank you so much ladies, this house is driving me crazy.
