I figured this out years ago because I am short and we have lots of windows that need to be washed using a step ladder. Buy an inexpensive liquid dishwasher detergent (for a dishwasher) that has a "sheeting action" in the soap. Fill a bucket with warm water and stir in 1 cup of dishwashing detergent (for a dishwasher).
Go outside and set up your garden hose for rinsing the windows. First rinse the window with clear water. Then using a sponge mop on a handle dipped into the detergent, wash your window. Follow with a clean water rinse and let dry. The sheeting action of the detergent will leave the windows streak free.

I hated cleaning our outside windows. It was a lot of work. Expensive too.
Cleaning the outside of windows the easy way using Cascade and hot water.
Clean your windows with just water. I slightly dampen a clean terry cloth towel/rag with water and clean my windows with them. You may have to experiment to get the towel just moist enough to do the job without getting it so moist it leaves water spots.
I know that everyone who loves this particular site will love this tip. For cleaning mirrors, etc. I don't bother making any concoction; I just use my empty bottle of all purpose cleanser (that I always keep in a spray bottle anyway).
I have a huge bag of my husband cotton T-shirts he has discarded, so I started using them to clean all my windows. I am so happy, my windows look great.
Use vertical strokes when washing windows outside and horizontal for inside windows. This way you can tell which side has the streaks. Straight vinegar will get outside windows really clean.
Instead of using paper towels or newspaper for cleaning your windows, try using the collection of wash cloths you have and never use, or pick up some cheap ones at a yard sale. They do a terrific job with a lot less elbow grease and there's no lint on the windows or black on your hands.
If you have a problem reaching for cleaning windows or anything high inside or out, purchase a telescopic window washer; the kind they use for cleaning bus windows. It works like a charm!
I ran out of paper toweling and I don't want to buy any more. I used a cloth baby diaper to wipe down my windows and mirrors.
Mix white vinegar 50 - 50 with water and put in a spray bottle. Spray it on generously. . .
Try using newspaper to clean mirrors and glass. First spray on the cleaning product, then wipe dry with the newspaper. I find paper with just black ink works best, and not slick, shiny paper - just plain old newspaper.
If you have run out of window cleaner, use a damp newspaper. They work really well and do not streak the glass.
Joy dish detergent works great for cleaning glass tables and windows. It doesn't leave streaks. I use it faithfully.
Forget microfibre cloths and proprietary cleaners. Place a sheet of newspaper in a basin of water; if it doesn't disintegrate, it's ideal for cleaning glass (windscreens, mirrors, and panes).
It can be frustrating to wash your windows only to see streaks instead of clear panes. This is a page about washing windows without streaks.
A little dish washing liquid added to water and ammonia work well to clean and leave you with streak free windows. This is a page about clean windows with joy dishsoap and ammonia.
