Wash
†
† Use a two-stage countercurrent-flow wash. For a single-stage wash,
double the replenishment rate.
If your minilab uses a final rinse step instead of a final wash, eliminate
both washes. Use three countercurrent-flow final rinse tanks with a
minimum final rinse time of 2:20 (0:47 in each tank). Use a final rinse
temperature of 38 ± 3°C (100 ± 5°F) and a replenishment rate of
40 mL/135-24 roll (36 mL/m).
