Has anyone ever discovered how to get rid of sticky old grease on a kitchen

Nothing seems to shift it.

One of the best things I've found for that stuff is Tesco cleaning wipes
+ elbow grease. If you're really serious then oven cleaners/hydroxide
will shift it but can damage the finish on surfaces.

However the Tesco wipes are very good at degreasing. Another good option
is the "Mr Muscle" degreaser sold for use in commercial kitchens. It's
not sold in supermarkets but you can get it from Cash & Carry stores
such as CostCo, Bookers or Makro.
