I have 2 Technics SL-D3's that have been in storage in temperature controlled conditions for a few years since 2006 then with me in plastic storage boxes for 5 years. They haven't been used since 2006, I purchased them in 1979 and kept them in vg condition only using to mix music. I was prepping them for sale and happened to lift the rubber mats on top of the platters and there was a layer of oil underneath on both tables. The oil didn't seep into the holes of the platter to the drive mechanism. I cleaned up the oil on the platter and mats. Both tables are functional.
Is this normal aging of rubber given they're 35 years old? The mats appear to be drier and shinier than I remember. I included some photos to show what they look like.
