Clean my windows?

I've tried every method, spray and cloth, soap water and squeegee, rolled up newspaper etc

How do you clean yours?

I rarely clean my windows. When I do, I just use water and washing up liquid, and rinse with water. Does a reasonable job. I don't care if there are smears, and don't care what the neighbours think.

I kracher mine with white vinegar then hoover it up and use a minky glass cloth to buff.

Do not do them when the sun is shining on the windows as it'll cause streaks.

I usually just use a glass cleaner and kitchen roll. I think kitchen roll or blue roll works better than a cloth.
I could never use newspaper because the noise of it on the glass makes me cringe 😬

Window spray in a bottle, smear it round with a microfibre pad thing, then hoover with the Karcher window vac.
Like pp said not when it's sunny as the water out of the window spray evaporates quicker than it should and it causes streaks. So front of house early in the day then back of house when they sun has moved round.
