Whether you have tiles, wooden floorboards, rugs, or other types of kitchen floors, cleaning them is a pain. The problem is if you don't clean every day, some stains harden up and are harder to remove "later on".
What is your preferred way to clean your kitchen floor?
We have tiles and use a mop with disenfrctent - I say 'we', but we actually have a cleaner to do that once a week. The only other clean it gets is if someone drops something, and then it is a quick wipe with a cloth or a sweep with the dust pan and brush.
A good steam mop is my choice. They clean well and easily. We recently bought one for my mother-in-law. Up until then she was still washing the kitchen floor on her hands and knees with a scrubbing brush.
