Clean windows, outside: the method, and where to stop.
A spray bottle and paper towels leave glass that looks worse in the afternoon light than it did before. The method that works is no secret: a squeegee and a little dish soap, with the blade wiped dry after every pass. What it does take is an honest answer about how high to climb.
Why do windows streak, whatever the cleaner?
Usually it's the sun. Glass in direct light dries before the squeegee reaches it and leaves the soap behind, so wash the shady side first. After that, look at the blade: a wet blade drags water back across the glass, and a nicked one leaves a line on every stroke. Fix those and the product stops mattering. Dish soap and water is what the pros use.
How often should outside windows be cleaned?
Once a year suits most houses, usually in spring after the pollen finishes falling. Windows facing a busy road or under heavy trees are the ones that ask for a second wash.
What builds up on outside glass?
Road film and dust settle on it, and tree sap and bird droppings bake onto it in the sun. Over time, hard-water minerals and the acid from wet leaves can etch the surface, leaving fine scratches that haze the view for good. Run a finger across the dry glass: rough or gritty means grit is embedded and wants washing off before it etches.
How to clean outside windows yourself.
Skip the spray bottle; paper towels smear the dirt and build static that pulls in more dust. Mix a few drops of dish soap into a bucket of warm water and scrub the glass with a microfiber strip washer. Pull the squeegee across in one smooth stroke, and wipe the blade dry with a lint-free cloth after every pass.
When to hand it off.
Second-story glass that needs a tall extension ladder is the place to stop; that work wants extension poles. Third-story windows get a confirmed price first. Window cleaning is $— added to a plan or $— one-time, a window, outside only. Count the windows; that's the price.
Or never think about windows again. On a plan they're washed during a seasonal visit, $— a window, spread across the monthly bill. Plans
