I ordered the necessary chemicals according to Ilford's Reversal processing pdf.
They call for Sulfuric Acid but the concentration isn't stated. They do say that weak concentrations ie 10% can be used. Page 2 of the pdf on the right. I emailed ilford earlier in the week and i'm waiting to hear back.
I didn't order it from Formulary cuz i didn't see that they had it. They sell 45% concentration. Another source i found sells 96% concentration.
What concentration do i need?
I read that weaker concentrations aka "battery acid" are available but i can't find anything here in L.A. I tried several auto parts stores, they led me to water for batteries.
