I’ve using a spray bottle clean that comes from the dollar store, it’s called awsome orange.
It’s a dollar for a spray bottle full and a half gallon refill bottle is another dollar.
Just spray the heck out of it for a couple of days then start with a bristle brush to loosen up the heavy stuff while still spraying. Once every thing is loosened up you can use a garden hose to get every thing off.
It emulsifiers the oil and grease real well. I also use it in boat bilges to clean them out.
No bad smells either like gunk leaves.
Works for me.
