Thank you for your inquiry and also for your phone call. Most users report that they can deep clean 85 – 90 brand new records (both sides) with the 3/4 oz Power Cleaner.
The cleaning function is a manual process.
A 2 oz. bottle of Record Preservative can treat the same number of records 85 – 90 (both sides).
A 2 oz. bottle of All-Purpose Record Cleaner will clean ~ 240 – 250 records (both sides) and is a manual cleaning operation.
The RCM Fluid is formulated to be used in Vacuum Operated Record Cleaning Machine where the surface of a record is flooded with cleaning solution, then scrubbed and vacuumed. It is not designed for manual operation.
I hope that this information is helpful.
Best regards, Walter Davies
