We all know (if we are honest) that WFP isn't as
consistant as trad, but the more experinced we get, the more we work out which are the problem windows, how to identify them and the best way to rectify any problems.
Brand new windows, painted wooden ones or UPVC ones are fantastic, these should come up near perfect every time.
But over time, the windows facing south suffer from oxidisation, doesn't matter whether they are painted or UPVC.
Every house I do, on the side sides of the house that are exposed to the sun I check the frame of one or two with my finger,
If they have began to oxidise then the frame will get a cursory wipe, and the glass a thorough one.
With UPVC, the glass is bedded in with a rubber seal (usually), this at least allows you to wash right up to the seal, and even with an oxidised frame you should still be able to do a top job.
On wooden windows it isn't so easy of course, if the oxidisation is really bad I'll sigh to myself and spend ages on a first clean really scrubbing the frames, I'll do several windows and then go back and start over just doing the glass.
On upstairs windows..tough...the customer can like it or lump it
but on the downstairs windows I'm happy to go back over them with a squeegee.
Technique isn't that important, I'll happily use a microfibre to wipe the squeegee and just swipe & wipe, not bothering with 'fanning' at all
You don't need to detail, so it is only seconds a window.
but mostly I get it just about ok with WFP, I only have a handful of windows where I need to go back over them with the squeegee.
Though I'll bet that on most houses that any of us do, there will be a pane or two that have spots, not many perhaps, but if you were doing the insides you'd notice them.
Having said that, if you have trad cleaned a house on the outside, and then have to go on and clean the inside, you will more than likely come across a pane or two that have smears, a little run, or a line or two from the squeegee.
