Hi Pat,

ATF 90 - Automatic Transmission Fluid SAE 90

You can rinse the membranes with fresh water with the pressure knob fully anti clockwise i.e. no pressure.
If you pressurise the membranes with fresh water you will ruin them - if they are not already ruined from sitting pickled for that length of time.
