keep at it guys, it will all come good, on first cleans 1 and 2 clean the frames and glass, then go back to first window, any excess water should be dried up, then just wfp the glass, after a couple of cleans the frames will have no dirt left to drip on the glass, after that its all plain sailing, the best advice i can give, is wet scrub air vents, never fire water directly into them, i use pencil jets only, you have 100% control of where you aim the water,
