mine was sorta like that,, it was manual labor.
letting the chassis sit up on one of the sides, i did a soft paint brush application / scrub along with tooth brush letting the liquid run down to the pile of folded shop rag it was sitting on.

my cleaner was rubbing alcohol,, its cheap, it penetrates and the 70% stuff wont evaporate off so quickly.
it did slightly take off some ink stamping but i was careful.

i also did the air gun on it as well to get water droplets that were "stuck" in areas to move along and "down".

i had all my tubes and transformers off the chassis before i did this and i avoided getting the cleaner in the IF cans.

of course i had to re-lubricate everything that needed to spin, twist and roll. the Tuning caps ball bearings and such which i used winter green lucas engine assembly lube since it is really sticky and doesnt run away ,, just sorta stick to what its stuck to.
