White cloudy film on inside groove of an LP


I received two new albums from an Internet music retailer which are from Simply Vinyl. Both of these albums have a whitish clear film on the last track on the second side that reminds me of a coating. In fact, I thought that it was a complementary coating from the record dealer. Unfortunately, the coating has a very crunchy dirty sound when the needle gets to it. It is very frustrating. I talked to the dealer who said that he does not have a clue of what it is. The rest of the record plays and sounds fine. Has anyone else had this experience? The last time that I went to Ambrosia Audio I showed it to the guys there they have never seen this before. I have even tried to clean it with window cleaner. It is just odd that it is on two records on the last track and into the out grooves. Can anyone help?

This is a common phenomenon on used LPs, although I have not found it on LPs I bought myself new 30-40 years ago, possibly because I have put them in good quality inner sleeves, which suggests that it may be trapped water vapor held against the vinyl over time. Mold release is an interesting theory, one I have heard suggested but have no proof of. I have found that putting a small amount of denatured alcohol on a cotton swab, running it around the groove surfaces, and IMMEDIATELY washing it off in a vacuum machine works well, but you can't let the alcohol sit on the record because it will destroy it if not washed off. Following that up with a dose of LAST 2 preservative usually does the job.
