We had a bit of bad luck with a small leak where rainwater got into the lp New Arrivals shelf, and several lps that were not already in a protective plastic outer sleeve (as they were all factory shrink-wrapped) got a bit water-damaged. The shelf was quickly moved and the affected records were completely disassembled (vinyl out of inner sleeve out of outer sleeve, which had its shrinkwrap removed), so all of the vinyl is clean and there is no mold damage or smell on the paper, as we luckily caught the issue within hours.
This is a list of the damaged lps, with a rating/description of just how damaged:
Anderson, Jason - Restless (Salinas Records) 4: outer sleeve more water-stained than wavy; insert a bit wavy
Bauwaves - U R Everything (Salinas Records) 5: bottom pretty stained & wavy
