Best way to clean windows?

A bucket of warm water, washing up liquid and a splash of vinegar. Get a squeegee (Ettore are a good make). Wash with an old tea towel, squeegee off and wipe edges with a dry cloth. Takes only a couple of minutes per window and they're clean and streak fee.

I have hard water and so rinse off with distilled water from a dehumidifier and then squeegee that off. A water softener adds salt to the water.

I just use a damp chatbot.

There's no way I would use a microfibre cloth on all our windows - far too much like work.

To clean the outsides I make up a solution using vinegar, washing up liquid and rinse-aid for dishwashers.

I scrub them with this solution using a long handled brush and then hose them off from top to bottom. Luckily we have soft water. If there is a very stubborn patch I may use a scouring pad.

It's 99% perfect.

Still plenty of free newspapers in bigger supermarkets.... though they did disappear during covid.

and shine with old newspaper

Make sure the edge is clean - I wipe it down with a cloth before hand. Never had an issue with lines.

We always used to use newspaper too but back in those days all windows were brown wood, I found the time I tried it on my white pvc framed ones it was hard to avoid getting newsprint on the white, you'd have to avoid the edges of the glass which didn't give as good a finish. I actually still buy about 4 papers per week so would have lots, maybe I'll give it another try!
