Dear Yogeshg,

Yes, you are right, the final rinse must be WFI, Usually in washing machine different washing cycles are define, in which it depends whether you can use PW for initial rinse or use recycle WFI.

Thanks

Dear Yogeshg

WFI should be used as a final rinsing but you must ensure that the rinsing is completed by WFI to prevent the microorganism level down and endotoxin level in limits.
