Fred I would not put windex anywhere near your mirror. It often has impurities that cause streaking. You can filter these out some what through high grade filter paper but still.... Ammonia in water forms hydroxide and this can attack the ali and etch the glass. It will only be about 3% ammonia but still not necessary when detergent and de-ionised water can do the job without risk.
