Well, once again, let me play know it all
I have a stainless Sub-Zero fridge and Bosch dishwasher.
With little kids, and with husbands who delight in fixing lawnmowers before lunch, you will most certainly have fingerprints...I use a sponge, dish soap and water, sponging in the direction of the grain, and follow it up with a stainless spray every few weeks. Scratches will come out with very fine steel wool, 00 grade, then definitely the stainless spray.
My older fridge is not a magnetized front, so if you want to display the children's artwork, get one that is.
What did you decide about the floor?
