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.
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.
