I have matching stainless appliances, and young kids, I don't find them any harder to keep clean than our old white ones.
I do want to stress to you a lesson that I unfortubately learned the HARD way:
RESEARCH YOUR CHOICE BEFORE YOY BUY!!!
Dummy me was so thrilled with the looks /style and price of our appliances that I never even thought to check out reviews and ConSumer Reports. (I used to check CR for every major purchase, maybe I was just blinded by the shiny, or just exhausted and wanted done with shopping)
WELLLLLL... our appliances (dishwasher, range and fridge) all have the absolute worst ratings/reviews, and have been nothing but problems for the last year (only a year old)
Don't be a (ME) and rush into a purchase without reading those reviews!!!
