I use Dr Bonners castile soap for many things- all purpose cleaner, kitchen cleaner, bathroom, floors, and even laundry sometimes. A little bit goes a very long way. I am starting to use white vinegar as well- as you say, it has so many uses and I learn more hacks all the time.
I am still a fan of mop and glow, and scrubbing bubbles for my shower. That's about it for the usual cleaners though!
