Cleaning Oil from Under Vehicle

[capejeep99]

While I'm crawling around under my Jeep to replace the clutch I'm seeing a lot of oil all over the place. I think the oil pan gasket and main rear seal are needing to be replaced and am now planning on doing that when I have the transmission removed. I'm asking if anyone can suggest good ways to kind of clean up the oil mess that is covering the components. I'm thinking just brake cleaner and rags and having a go at it all. But any suggestions would be appreciated. Thanks.

Before you jump to conclusions about the rear main and the oil pan, check for leaks from above. The valve cover gasket and the oil filter adapter are common culprits.

As to cleaning, engine degreaser exists for a reason. Oven cleaner may work even better. Just keep your eyes safe.
