The oil was completely removed. To be fair, I think that had I started by agitating the part during its immersion or afterwards with a brush before washing it off, then doing so in warm water, the results would have been better as I have seen deposits worse than this come off easily when using some form of agitation, whether that be higher water pressure or manual agitation with a brush or rag. You might notice the rubber bushing insert on the left appears to be dirtier in this photo than the previous, that is actually rust that has dried more completely and shows up better against the black bushing. I used this bushing to show the effects of Rusteco on rubber in a test in the next section below.
