How do I spray the outside windows with out spotting?

Huh, good to know! Thanks. I have my windows and screens professionally washed twice a year and once a month I go around and use a hose, vinegar and newspaper and a old 100% cotton towel.

I use Windex in the bottle you hook your hose too, and a squeegee on a long pole... no spots.

Try vinegar. Mix with water. No chemicals.

do your windows at night with your lights on inside and you can tell when your windows are streak free

Vinegar and newspaper should really help!

white vinegar mixed with water 50/50 a dab of blue dawn ,and a dab of jet dry

I am an old coot and can't get up on ladders anymore as I fell and broke my pelvis...so....I just sprayed my windows to get off the dust and then made a solution of dishwasher rinsing additive ( you put it in the little compartment in your dishwasher and it helps sheet the water off your glasses) and I got a wand with a little bottle attached at the hardware store.(.I think it is for washing your car)you fill the bottle with a little of the rinsing additive and water and then spray your windows allowing the additive to go on the windows just for a few seconds and then I was done and my windows looked almost as good as when I paid to have them done and I can do them whenever I want to now...
