Even with a cooking hood, well used kitchens have a degree of grease on
the walls and cabinets. Ceiling too, of course.

TSP is a good cleaner but not so much for greasy areas.
If you're going to clean and repaint, try "Greased Lightning."

Even better is "Wilbond" but you won't like using that. For that, you
need to open all windows plus wear a full filtered respirator (not a mask).

Both products are available at some hardware stores or paint stores. A
quart of either should be enough for a kitchen.
