If the glass cleaner is ammonia free (most good automotive glass cleaners are), there shouldn't be a problem. However, it's always best to check the owners manual, or contact the manufacturer to be on the safe side.
I used eagle 20/20 on mine and wiped with paper towels . Then went town with the vanilla moose and a sueded MF and put a coat of Optimum wax on it . QD'd with Z6 the next day .
I've been told to avoid using anything with ammonia on my glasses (anti-reflection/glare/scratch coating). Actually, I was told this after I brought my glasses back to the optician to have the lenses replaced-I used a foaming cleaner that had some ammonia in it, and the coating "crazed" almost immediately.
I just got new eye glasses with anti glare coating on them and the dude at Lens Crafters told me to only use the cleaner that they sell. He said that you can get it at Lens Crafters and Wal Mart and a few other places, but he said you can damage it by using anything else.
I think it would be wise to use a cleaner without ammonia or alcohol in these circumstances. The Plexus website says products containing the above ingredients can cause certain materials to dry out and discolor over time.
