Powerful cleaner for embedded grease/dust/dirt on top of kitchen cupboards?

[MyrtlethePurpleTurtle]

I recently made the mistake of standing on a step ladder in the kitchen and saw the state of the top of the cupboards - primarily those in the cooker area but not exclusively so. And oh my, the deep 'grease' with embedded dust/dirt.

Any idea how to clean? Specialist chemical cleaners? Elbow grease ineffective. (Non chemical cleaners like white vinegar, baking soda etc entertainingly ineffective).

There must be products available. I mean, how else would specialist cleaning companies and professionals do this type of cleaning? (Or do I just leave as is 🤔 )

Many thanks!

Apologies- I should have explained it clearer- you need the towel to keep the warmth in if that makes sense. The heat from the towel melts the grease and the washing liquid helps to lift it.
