as far as pressure washing is concerned. my answer is use what you got. doesnt really mater what kind or pressure you have. you just have to use some good degreaser, scrapers and time. i have used easyoff oven cleaner and gunk engine degreaser and many others but you still need to scrape and scrub to get it all off. take your time its going to take many many trys to get everything clean then you will find more that you missed. patience is a virtue when cleaning anything old. take your time and be ready to get really dirty and wet. i bet i pressure washed my 51 for two weekends straight and i still had grease and debrise to deal with when disassembly time came.
