Most of us that went WFP did so without training. We find a system that suits us, and get on with it. I have yet to watch an experienced WFP user doing the job.
Take rinsing, We know how to wash and rinse a pane of glass, but what is the best way to do a series of pains as in a conservatory?
Up to now I have been washing, rinsing, move to the next pane. I realised today that this way takes longer. Why? Because I am washing the next pane carefully, so that dirty water from the pane I'm washing, doesn't splash onto the pane I have just rinsed. I was much quicker when I washed one side of the conservatory, and then rinsed the lot before starting on the next side.
I didn't have to be careful about splashing the last pane as they all had to be rinsed after.
How do you do it? Rinse the pane before moving to the next, or wash a few and then rinse the lot. Dai
