Don't laugh, I acquired a used dishwasher from an apartment building that was being refurbished (actually two of them). I had one set up in the basement to clean what ever I needed. I filled it with a 50/50 mix of Purple Stuff/Purple Power what ever they call it these days and let it run, it heated the water mix and everything. I had the drain hose fed into a 6 gallon container, when the cycle was complete it pumped the mess into the container where the solids could settle. Then pour most of it back into the washer the next time it was needed, leaving the settlement in the bottom of the collection container. I could get 5 or 6 really dirty cleanings before I had to change the mix. The washer I had would fit a TR7 engine when I removed the top tray. Ok, it wasn't easy but we got it in there.
A good used dishwasher is the best cleaner a backyard mechanic can ask for[:)]. Just make sure you pull the parts as soon as they are clean, blow them dry and dip/paint them with oil ASAP because the degreaser does what it says and all your rust protection is gone![:0]
Alternately go to the local car wash and have at it with the high Pressure.
