I wouldn’t expect a used record store to be cleaning their inventory. These are shoestring mom and pop stores and probably carry a lot of unsold inventory. They could be wasting thousands of dollars cleaning inventory that they never sell. Alternatively they might clean it upon purchase and wind up selling it a few years later and it might reacquire some dust in the interim and lead to customer complaints.
Ironically one of the two records Purchased looked better in the store but sounded far worse than the other, which had obvious issues on inspection.
I appreciate the offers to come to peoples homes and use their machines but I live in Chicago. The store is in Oak Park, Il. and called Val’s Halla. Val probably was reselling lps before CDs came out. She worked hard to keep the vinyl flame going during the CD era, doing her own record days and many community events, lugging playback equipment and records with her despite severe COPD. Hopefully she made a few bucks from the vinyl revival before she died a few years ago. The store was slated to close but her nephew, a true analog apostle, and who has a “regular “ job, is busting his butt to keep it going. Although I don’t intend to buy many records for reasons stated in the OP, I wish them luck. The inventory is well arranged and easy to work with and I can be responsible for my own record cleaning. I suggested to them that they buy a nice cleaner and charge a fee but its a step to far for them
