I am shit at cleaning. If I cleaned for 20 hours my house would look tidier but definitely not shiny clean.
I have had several cleaners ad hoc or for a season and they have always amazed me with how much cleaner they get the house.
Maybe I am just particularly bad, but I do think it’s a skill and we should give a bit more respect to those who do practical jobs. Calling it unskilled seems insulting. Just look at all the blogs and insta influencers who make a career out of training us mere mortals in how to do it better.
