The cheap foil wrapped doors aren't much better than a painted finish, you only have to look at them harshly with the jif and they start to bubble and you can forget using a brillo pad. I watched a few youtube cleaning video yesterday and seeing everyone just spray and wipe to clean their apparently dirty kitchen and bathroom makes me want to shout BS.
I think next time I'm not going to bother with wall cabinets either, just a couple of larder style ones as far away from the hob as possible, the underside of them is rank.
