Why does my homemade window and glass cleaner leave streaks?

I have been cleaning the glass shelves in my fridge and my windows with this formula:

1 quart water
1/4 cup vinegar

I don’t have a spray bottle right now, but I use a sponge. I like to use organic and environmental friendly products. I have allergies and sensitive skin.

*I tried drying with both newspapers and a microfiber cloth. I still get streaks. You can see the vinegar residue.

So far, no problems cleaning my mirror.

Any suggestions?
