I pulled in the garage and could smell it immediately! I went at it with Malco interior cleaner, which I've loved for a few years now. No odor, nothing, it's like liquid magic eraser. Hasn't ever damaged a single thing I've used it on. MF rag, Phil's gentle boars hair brush, bucket of very warm water, lather it up good, rinse the rag a LOT, change the water a couple times when you see the oil slick on top. It'll be gross, I promise.
Then when you think you're finished, it will start oozing out of the little crevices again, just like an oil slick. Be warned! But it can be dealt with, just have patience. If it's the right car, go for it.
