I think ammonia will dissolve some plastics.  Acrylic glazing, for example, should not, apparently, be cleaned with Windex with ammonia.

I think, however, that the small amount of ammonia in Windex is part of, if not the main thing, in the mix that will dissolve the binder that might be holding the pigments together and causing the clog.  I believe if Windex with ammonia is used for relatively short times -- like overnight -- on the parking pad, it will not do any harm.  This remedy has been used quite a bit without any negative reports that I know of.  That said, a high concentration of ammonia in a cleaning fluid might be harmful from what I've been told.
