You should ask Squeaks how much he spends on his photobraphic equipment!!

!!
With regards folding scrims, microfibre and so on: Mine often start out folded, but often on leaded work, the lead drags against the cloth...within a short time it's unravelled into an untidy mop

But I've found little difference myself, so long as you keep rotating your cloth you'll be ok.
And squeaks, if you are daft enough to mention WFP in the same breath as trad, and are talking about speed, then of course people will mention WFP and compare times!!!
Perhaps it is actually getting to the point when there needs to be a separate section for Trad and a separate one for WFP, this way any thread started on one or the other topic can't get hijacked into trad V WFP (usually by Squeaky himself!)
Something I also meant to mention regards speed with leaded V squeegee:
Roger claims he is quicker doing a leaded with a Microfibre cloth than he is doing a similar window that is not leaded with a squeegee.
If this was so then surely you would use the same method on windows of a similar size that were not leaded. Patio doors and big plate windows you would of course do with a squeegee.
But were you to clean these others windows with a cloth, once the sun shines on them they would be as smeary as hell, and in truth, to get a job that would equal the finish given by squeegee-ing and detailing would take far longer than it would with the said squeegee were you to use just a spray and micro cloth (or damp micro/scrim)
I started window cleaning over 22 years ago, I was using chamois leather's to clean windows, including big panes and patio windows.
Da
mn hard work I can tell you, and a high level of skill is required to obtain a top finish.
But it would not equal the finish you could get with a squeegee, you could of course be quite quick too, but the squeegee was less effort, did a consistantly better job, was almost always faster and left you better off and less exhausted at the end of the day (Am I ringing any bells here

)
So the actual job you are doing on leaded windows, if looked at properly is highly unlikely to be of an equal standard to those done with squeegee.
I don't use WFP on everything remember, I use all methods and am continually comparing results.
I know how to use all methods and can achieve top results with any of them (including Chamois leather, very few window cleaners, unless they have cut their teeth on Chamois can say that).
Anyway, my new computer has just arrived
I'm off!!
