started wfp about 2 week ago and although a lot are coming up well some are leaving runs when dried.. 

so some do some dont? these are p.v.c frames so cant blame old paint or such..

does it maybe take a few cleans to get rid of all the old detergant? they'll all scrubbed the same, some are perfect, others run!!

I would give them a really really really good scrub to get the soap off. Scrub the top edge like mad and rinse really well. May take a couple of goes

Some just don't come up good, no matter how long you scrub them

My method for a first clean wfp.

Go round all the top windows scrub everything - including the glass and cill like mad and make sure the top frame is spotless including the vents.

Then go back to the first top window and just clean everything below the top frame again and go round the house again.

Now clean the bottom windows in the same way.

One exception - if you have two openers above a large full width pane then do the two openers and the frames first and make the bottom pane the last job of all as otherwise water drips down the middle of the bottom pane and leaves a run or spots.

.....

On repeat cleans do the tops on one side of the house then the bottoms on the same side.

you really do bottoms straight after tops on same side? I always worry as tops are still dripping

[AuRavelling79]

Yes, usually if there are say three windows up top I'll do the top three then say the door or porch then the two exposed ones below. I might do the side tops first if there is too much still dripping. I always run the brush along the top cill "dry" at the end of each window before doing the bottoms.

when on repeat cleans do you scrub all the tops of frames again or just the glass?

[AuRavelling79]

If it's monthly then I do the top frame every second time. If they look ok I might let it go to the third time. But once they're done it only takes a few seconds the next time.

they will come up good in time about three cleans ive found

[trevor povey]

I think that you must leave the job to the standard as previously supplied when trad....telling the customer they take three times to come up is a cop out...get up a ladder and check them off yourself before leaving the job...at the end of the day most aren,t interested in how you clean the glass.... there just interested in clean windows.

thats true trev.. i keep checking them but some dont dry for ages and there's only so long you can hang around.

You shouldn't need to wait for them to dry to see if you are going to get runs. You can tell when they're wet. If you see a small line of dots going down from a seal then you can bet it will spot into run. Sporadic spots is what you should be looking at (if its that type of glass). My advice would be to keep off the seal as much as you can with your jet of water, rinse above or below seals but not on them. Use the brush with no water flow to remove excess water, drips. High water flow as touted by many as being great for fast rinsing can actually cause you problems if its to fast and hitting seals, nooks and crannies.My rule of thumb and i may be wrong here, but if i can hear the water hitting the glass then its to fast. Slower flow in the right places may actually help you.

that is very true I can spot that run when when wet straight away. I disagree with the fast flow though, but I keep the brush on the glass and away from the seal if it is a problem and all is fine but I also agree your method will work, I think there is lots of ways of ensuring a good job and many find it by looking at the glass they are cleaning and learning however you do it.

or you could try sticking an immodiam plus in your tank that always stops the runs
