When I notice that the accuracy is going down. So around every 1000 or so rounds, if that.
Glock hasn't been cleaned, except for barrel, since I got it.
Everything gets wiped down with a silicon cloth every now and then.
About the only ones that get cleaned spotless are the engraved Thompson and the carry guns (to a certain extent on the carry guns), all others are whenever.
And no, not had a problem with rust, dirt, function, or accuracy.
