Grandchildren are wonderful! And the approach is very correct! When we had a child, we also approached this issue very seriously. While I was in the hospital, my husband did a general cleaning of the whole house. And even cleaned all the driveways, the entire yard and the garage! Of course, he did not do it himself, but turned to Window Washing Pro
https://window-washing-pro.com/residential-services/power-washing-services/ for their services. No amount of traditional and manual cleaning can ever compare to how these guys can do their job. Highly recommend, you will like it
