@deadlift,
Here are three cleaners you can try as a soak (try a spot) that you likely have in your home and will not harm the record:
-Isopropyl Alcohol - standard store bought 91% - soak a spot for 15-30 min (you will have to reapply as it evaporates)
-Laundry detergent such as Tide mixed 1-5% (1-5 mL/L). Quality laundry detergent such as Tide has a broad variety of surfactants and enzymes and the enzymes 'may; work.
-Distilled white vinegar (DWV) with a few drops of dish detergent to act as wetting agent. The DWV is 5% acetic acid and the acid 'may' work against the film depending on what it is. The DWV needs some surfactants to reduce the surface tension so the DWV can 'wet' the surface.
It is possible that the record was stored at too-high a temperature for too long and what you are seeing is a breakdown of the PVC and this is not recoverable. At high temps PVC releases hydrochloric acid (HCL) and the PVC contains ingredients to scavenge the HCL, but expose to heat for too long and the HCL scavenging ingredients are depleted.
Good Luck
