Some of you know I was cleaning my vinyls in a fascinating way sometime ago.
The method includes use of PVA glue on the discs to get rid of the dirt - glue does not stick to the plastic but it does to the dirt, and once dried it can be peeled off. The longer it dries the easier it comes off.
While the peels are "negatives" I tried to play one and lo and behold it kinda worked hahaha.
I had to reverse the recording though, and you can find it here along with other other photos of the process.
