V.I.P. rinse programs


Fellow netters:
    My lab uses zinc formalin as the primary fixative. Sakura recommends a 
water rinse to routinely flush out potential salts from depositing on the 
O-rings and rotary valves. A recommendation was made to use glacial acetic 
acid in approx dilution of 200ml per gallon as a wash for removing the zinc 
from the mechanism.
    My question is what might the recommendation as to frequency of using the 
    Any help would be greatly appreciated.
