Using corrosive ammo,should the gas tube on semi auto rifles be cleaned after each firing session? I don't think that much gas actually passes through it,and some tubes are not even removable,MAS 49-56,for example. I use Windex with ammonia to preliminarily clean the bore,but I am afraid to try and put this into a non removable gas tube. I've noticed on the SKS and the AK that hardly any residue is left in the gas tube. What are your ideas on this,Thanks! :)

Follow the instructions in the Owner's Manual that came with the rifle.
It would help the rest of us to know if you're talking about a specific rifle type, or all gas-operated semi-automatic rifles in general.
Personally, I don't see how flushing out the gas tube with hot water could cause a problem. Hot water dissolves and washes away the salts which are deposited by corrosive ammunition. A mix of Windex and water does the same thing, but may leave a little bit of ammonia residue behind.
Either way, you could use compressed air to blow-out any remaining liquid and dry the gas tube afterwards.

The salts go anywhere that any of the gas goes, so the gas tube needs flushed with a water based solvent.
