Hi All, I'm getting the odd spotting issue and pretty sure it's down to having some runs from the top frame/seal. I seem to be having too much water left on the frame/seal when I'm cleaning them. There's obviously a fine line between cleaning the frame well and leaving them dripping ? I definitely don't seem to get the balance right !! As a newbie, I'm just starting the 4th set of washes for my 1st customers right down to still doing quite a few 1st cleans. I do take ages on first cleans and rinse rinse rinse but still left with spotting sometimes. I'm now using a gardiners clx and hybrid brush and a small pole with a flocked brush downstairs. the problems are the same with both which makes me realise I have a **** technique, despite reading loads on here. My own patio doors are the worst and they've been cleaned ALOT lol the practice doors ! If you wash the top seal then go back to the window a couple of minutes later, washing/rinsing an inch below the seal, how does the top inch get clean ? It's horrible going and cleaning houses with zero confidence, even though I've only had 3 complaints. One of them was shocking (wooden frames must have oozed ****), and looked like I'd chucked a bucket of dirty water over them. Very embarrassing Help !! My water is always 000.
