Glass cleaner

I tried my multipurpose cleaner on the bathroom mirror and I'm not the happiest with it. It looks fine close up but from far away, you see lots of little streaks. I could try wiping with newspaper and see if that helps. Otherwise, I think I'm going to make a separate cleaner just for cleaning glass since I found an interesting recipe:

Glass Cleaner

1/4c rubbing alcohol

1/4c white vinegar

1T corn starch

2c water
