Nickel Tub

What are good ways to clean except the granite countertops and brushed nickel? What about wood floors?
I just moved to a new home. There are many different materials for the devices I'm not used to clean! I'm cleaning no more, and I cleaned the house for a month. However, I do not want to use the wrong products in these expensive machines New! It is made of granite, brushed nickel, wood, fiberglass tub and cushions on the bus? Any advice would be greatly appreciated!
A bucket of nasty Armstrong floor cleaner and clean everything.
