Quoted:
Some advocate the use of Windex in the belief that the ammonia will neutralize the corrosive salt residue left by the corrosive priming compound. There are 2 big problems with this theory. You can not neutralize a salt, you have to dissolve it and flush it away.
The other big problem is that Windex does not contain ammonia. Look at the MSDS, no ammonia listed.
If you save you empty Windex bottle and fill it with plain tap water, it will be just as effective as the Windex that you have been using.
Or, just wait until you get home. Unless you live many hours from the range, you will have plenty of time to clean it up properly after you get home.
Windex is mostly water, and it dries fast.
Hot water also dries fast.
The trick is not to leave the weapon soggy after the rinse. The active ingredient is WATER. That's what dissolves the salt. The problem is what the water does to the steel itself, and there are many effective answers.
a 1/10 ballistol/water mix doesn't dry any faster than straight water, but it leaves oil behind in it's wake. I use that.
I saw British military surplus tin funnels with long spouts once, they were made specifically to fit in the breech end of the Enfield rifle so that boiling water could be poured through.
