retainer formula

[Bralors]

Hello, from Argentina, I'm looking for retainer formulas with acetic acid, thanks

I think you mean a stop bath to halt (restrain) development a 1 or 2% solution is ideal, you can work that out from the strength of the Acetic acid you have.

Glacial acetic acid 17ml dilute to 1 litre with water.
