I have seen postings from people who claim to have worked in pressing plants. Some of them claim that they used mold release compound. Some claim that it is a residue from the pressing process. Some claim it does not exist. Others claim that it depends on the plant.
I suspect that I have seen an oily substance on newly pressed records. So I clean with an US cleaner and a good lab grade detergent, and rinse heroically.
