The house I'm in... the cupboards in the kitchen are just horrible for collecting anything and everything and looking dirty... they can get wiped down once a day and still look horrible, and like there is stuff all over them... and there are some greasey looking marks that no matter what I use I cannot get off... I've tried hot soapy water, vinegar and all purpose cleaners for grime etc and nothing seems to make them look clean...

So does anyone have any advice or miracle cures to make them actually look clean?
