How to wash windows easily?

Inside or outside?

Hire it done - especially if you have a multi-story house.

I suggest a vinegar/water mix and wipe it with a microfiber cloth.

Use Windex but wipe it with newspaper instead of paper towels, the newspaper doesn't leave any streaks or lint!

For the inside I do the same a TheHoneycombHome using Windex and newspaper.

Outside I use this mixture:

1/2 bottle of Jet Dry rinse aid (or approximately 3 1/2 ounces)

4 Tablespoons rubbing alcohol

1/4 cup ammonia

1/4 cup dishwashing detergent

2 gallons of hot water

Squirt water on the windows and using a long handled brush scrub and then rinse.
