Record cleaning fluid for degritter machine

If using 91% IPA, recommended amount is 2.5 to 5.0% and with the DG tank = 1,400-ml, the quantity at 2.5% = (0.025/0.91) x 1,400-ml rounding down = 35-ml.  For 5%, double the amount to 70-ml.

For Tergitol 15-S-9 buy this Nalgene dropper bottle Amazon.com : Nalgene Plastic Drop Bottle 2 oz. : Sports Water Bottle Accessories : Sports & Outdoors that delivers a precise 0.04-ml/drop and use specified in this free book: Precision Aqueous Cleaning of Vinyl Records-3rd Edition - The Vinyl Press, Chapter XIV Table XXIII Nalgene™ Dropper Bottle Use for Degritter™ & Humminguru™.   The Table addresses what you will get for various drops and whether a rinse is required.  Note that the number of drops for the DG is ultimately limited by the foam that can be produced as addressed in the Table.

Thanks.  I really don’t want to run a record through more than one cycle of the degritter.  Some people seem to recommend two washes, one with detergent and one with just water.  This would increase the cleaning time per record up to 15 minutes!  It would also require two separate tanks.  I don’t think I want to go that far.  

@billstevenson Thank you for mentioning the record cleaning book by Neil Antinn.  I was unaware of this well written tome on record cleaning. 

@antinn Mr. Antinn, thank you for making your highly researched record cleaning book available at no cost to us vinylphiles. In this day, that is extraordinarily charitable of you.  Hats Off!

If you view the book, Chapter XIV Table XXIII, you will see there is a no-rinse concentration that provides wetting only; no detergency.  To achieve detergency with surfactant(s), the concentration needs to be high enough that rinsing is recommended to prevent residue.
