In my experience, you should go for NaOH first and then go for acid washing. this way after a quick CIP you will have a neutralized surface of the membrane. check the permeate pH also. You may have to start over the alkaline and acid washing sequence with proper rising time in between and a CIP before turning the system into service mode. Use Iron-free HydroChloric acid in proper portions.

Good Luck.
