My 2 12" Stoky & the Phillies records did exactly the same thing, developed a haze that I didn't know should be attributed to what. Nice to know after all these years. I cleaned them with distilled water and a drop of clear dishwashing liquid on a Nitty Gritty and they cleaned up great... They still never sounded all that great though.
