I have big windows and electric karcher. I wash them down with soapy water, rinse with clear water then the the karcher but they streak so I polish them with Mr muscle. All with fracture of spine why does karcher streak. I am taking big breaks
I found this on the internet, it seems to suggest that you may wish to let your windows get dirty for a while.
'Your doctor might recommend bed rest for a short period of time. After several days or as soon as you start to feel better, gradually ease back into your old routine. For a few weeks or months, you may still need to avoid heavy exercise that could make your injury worse'.
JJ, my Jay or JJ as we call him is my reason for living as well. I couldn't bear for him to have to go back into Rescue again.
Re your windows, get yourself 3 Scrims. 1 to wet in warm water with a tiny drop of washing up liquid and squeeze out then clean window. Number 2 to dry window and No.3 to polish it. You will not get any streaks. So easy and work brilliantly.
