I recently bought about 50 records at a garage sale and most if not all were plagued with fingerprints. It varied from a few to practically covered in them. First of all as a record user and fan, there is no excuse for putting a finger anywhere on the surface of a record. Garage sale records being sold at a few cents each I can excuse but I have also bought records from sellers with fingerprints. That is inexcusable. Being faced with all these records to clean fingerprints from and as a fan of solutions without alcohol and being very low on my usual Disc Doctor fluid I tried some new lens cleaner I have called Bi-Oh! made by a Canadian company.
It works with an enzyme formula to remove oils and I was more than pleased with how it worked. I’d wipe the record with a micro fibre cloth and distilled water, spray the Bi-Oh! on it and spread it with a cleaning pad, then wipe with a cloth and distilled water. Then a dry cloth to dry it with. The ones worth it, I then ran through my ultrasonic but even without that, the results were great with just the manual cleaning. My small bottle of solution ran out so I found a supplier and ordered 2 - 450ml bottles. Info here: Bi-Oh!
