Before or after

I'm using Record research wash and I'm wondering do I use the Vinyl zime before or after the wash. Also should I use a finishing rinse. I've read about people doing it both ways.
I do VZ first, RRL SDC second. The other way around would probably work just as well. I doubt it matters much.

RRL SVW should always be last.

No final rinse unless you have a source for double deionized, distilled water that's purer than RRL's. Most store-bought distilled is less pure, so don't use that as a final rinse. (Of course cheap distilled is fine for diluting VZ from the concentrate. Hyper purity would be pointless when you're adding enzymes.)
