Okay - so what crazy cleaning practices have you witnessed/heard about, or is there anything you do which is a bit odd maybe?
Many years ago when I was an exchange student spending a year in a European city, I shared a flat with a group of other exchange students from various countries. One of our flatmates clearly thought the place wasn't up to his (or his mamma's) exacting standards
. He bought some alcohol from the chemist's and proceeded to pour it all round the inside of the bath. He then set fire to it with a match 'to burn the dirt off'! There was a plastic shower curtain hanging over the bath; I can't remember what the bath was made of.
I am so glad I was not in when this happened because I would quite possibly have lost it with him - we actually had a cleaning rota and everyone did their bit every week and the bath was not dirty.
