Hi there. I have just spent £££ ! on a new FF from Siemens and it is fab, looks like some sort of spaceship in my kitchen, all shiny new stainless steel. However, I want to keep it looking like this- would just water and an ecocloth do the job? It is supposed to be fingerprint resistants (we'll see in a week or so when my teens have been in and out of it non stop) . Any advice- just want to make sure I don't ruin the finish by doing something stupid or using the wrong product.
