Any idea what this goo is on my record?

I received a really, really nice looking record today. Not so much as a fine scuff on it. Its a 1950's Prestige and as unmarked a record as I've seen. When I got it home the surface looked kind of hazy so I hit it with the Disc Dr, vacuuming off the rinse watter. I put it on the TT and the intro dead grooves are terribly noisey. The same on side B. It doesn't sound bad playing but the spaces between tracks and quiet passages are very noisy - scratchy like an old 78. No pops or ticks - the record is really unmarked - but noisy. The vinyl is still a little hazy looking too. Might this be some prior owner's misguided attempt to apply some preservative? If so, any idea how to get it off the record?
