I am looking for any ideas on how to remove excessive grease and grime off the frame and other suspension parts on the vehicle that I’m currently working on. The previous owner never fixed a leaking oil hose that leads to the remote factory oil filter. After a few years of adding oil and never fixing the problem, I now have a real mess to deal with. One nice thing is that areas I have cleaned, the frame is like brand new. I have tried oven cleaner and other degreasers but nothing really seems to make the grease disappear. Do I need to bite the bullet, put on my rubber gloves and go at it with a scraper or is there a powerful degreaser out there that will do the job?
