This fluid will be sucked into the green oxidation and does not leave a coating on top, but it does change the color of the green into a darker shade.
If the object is found in a salty type of soil it may have to be left soaking in a bath of water first to (try to) remove/dissolve all the salt.
Using acid til the bare metal is visible -as you might suggested- is irreversable and may degrade the object to a lump of metal/'just a metal axe'.
Good luck!

Salaams Indianajones, Some useful ideas there thank you. I will soak in a bath to remove any salt and clean it up carefully to get the dirt off ... otherwise I think I can live with the patina ... 4000 years ! It should last a bit longer. Regards Ibrahiim.
