I have so many really good original parts for my project but they are caked with years of grease and grime. For example I have a trans cross member that is just caked with years of grimy greasy crud. I was thinking of soaking it in a bucket with a concoction of a good mixture of a cleaning agent. My question is what should I use? Simple green? What are your suggestions? Also have parts like my awesome 1969 BB torqueflite that obviously won't fit in a bucket. Spray with simple green and wipe? Suggestions from my Mopar brothers and sisters would be appreciated! Thanks much in advance!
