Hello, doesn't look that bad, you can use a vacum with a dust brush first.

there are also a couple threads on washing down the insides using various combinations. Read each thread thru front to back before proceeding.
After doing it once and seeing the end result AND the unit still plays makes it easier the next time.

I'd start with a dry paint brush, perhaps a hair dryer or any way to blow air. When too sticky, I use isopropyl alcohol with a brush too, and rinse with more alcohol.

A small brush with hard and short bristles is useful to scrap some places, or in between resistors and components.

Compressed air is your friend. And not one of those cans, a real compressor with air gun.

I like a couple of cheap artist's brushes and a vacuum to remove the dust stirred up. It takes some time, but it is a clean and thorough process, and it lets you get up under things and in corners where air flow stagnates. It goes relatively quickly.

A little compressed air (Or your lungs) and a soft paint brush go a long way.
