2 part question...
How do you clean your hard floors.. yarn mop/wet jet/steam mop, etc. and what kind of chemicals, if any?
How often do you clean them?

We have wood laminate, and I used to use a yarn mop, I own a wet jet that I mainly use for spot-cleaning, and got a steam mop for Christmas that I love... but I still get streaks and they drive me crazy! I clean on Saturdays, but wondering if I should be mopping more often... doesn't help that we live in the country so there is constantly dirt/mud/dust being brought in.

Tell me your secrets to clean floors!
