1. Electrolysis. It will clean and remove crud, loose paint and rust in every crack, crevice, nook, cranny and pit. When done clean with a brush with soap and water. Works great.

2. Ultrasonic cleaner. Be sure to check out the inside tank dimensions so it's big enough for the job. Ultrasonic cleaners don't remove rust unless it's loose.

3. Detergent/degreaser a brush, steel wool, small brass or steel brushes on a rotary tool etc. Whatever works. Slow and tedious but eventually gets it done.
Most likely there are other cleaners, solvents, degunkers, varmish removers, rust dissolver solutions and other goop that it could be soaked in. Carb cleaner works most excellently on varnish, grease and petroleum based crud.
