It's the grubby little finger marks - they show immediately. I'm not the sort to spend time every day polishing my kitchen, and anyway, 10 mins after doing it, its back to looking grubby as ds1 and ds1 paw at it all. The hob and small oven/microwave are ok, but the main oven, dishwasher and fridge are all brushed stainless steel too.
Having all the latest cool looking kitchen equipment seemed like a good idea at the time..................
