Do windows that oxidise cause problems if water just runs over the frame as opposed to scrubbing the frame?

An example of this might be where you do a small opener at the top and the water runs down over the horizontal bar over the window below.

It seems to depend on a few factors but if it doesn oxidise it should only be on the top 2 inch of the pane. Luke

Give it a good scrub too or it will spot

So are you saying if your doing a house with frames that oxidise scrub them anyway?

[Captain Scarlet]

Try to just touch the glass and just get visible dirt on the frames if needed, Luke

Ok, got that, ta; but........will water just running over this part of the frames (the bar just below the small opener and above the pane below) become contaminated from them before it gets down to the glass below even if you dont scrub that part?

[Captain Scarlet]

Yes sometimes, but its seems quite random, depending on a few factors...ie is the aluminium bare or type of aluminium and age of aluminium etc etc. It wont always happen though. I only get two windows on my whole round that spot ( aluminium but you cant notice, it only spots right at the top ) Luke

I scrub the frames so that i am sure that when i clean the glass no dirt can be left behind to drip onto the glass
I am also probably a bit over cautious but that comes from not being confident of wfp when i first started and i have just carried on the habit and also i am a bit clumsy sometimes and stand on the hose and it pings the pole and water all over the place so i do the frames just to cut down on the possibility of anything happening
Once the oxidized frames have been scrubbed on the initial clean its a matter of a quick rub over on cleans after that doesnt take any extra time

So if you do a first clean on a house with frames that oxidise wil they bleed as much after?

Or will they eventually stop once theyve been done enough times?

If I ever do oxdising frames, I will scrub and scrub the top of the frames until I can no longer see milk running down the glass, if you are using a good flow rate and make sure you are thorough you can not go wrong. It will take longer, but I'd rather take twice as long on the first clean, than either make a mistake and look bad, or have to be extra careful every time I go back by making sure I don't touch the top of the frame.

Basically as long as you scrub and rinse for long enough, the oxidised layer will be removed (in my experience). Once the water is running clear again, go over it another couple of time to make sure.
