Leaving grey lines

My water is coming out at 0.00 but still leaving grey lines going down the windows,I’ve changed the resin and both filters,has anyone else had this problem and solved it?

Sounds like something on the glass or seals bleeding and running down to me ? 

Is it on all houses? Could it be the plastic frames “leeching” ?

I don’t think it’s the frames as there are too many lines,you can’t see them until the sun comes out!!!

No not on every window 

Is it coming down from windows with air vents 

After cleaning the frames and glass try drying the frame with a microfibre and just clean the glass, if you don’t get ‘lines’ the frames or seals are oxidised and need a ‘restore’. I assume you’ve made sure the lines aren’t there before you start?

There are no air vents and Ime sure the lines weren’t there before hand

Sounds like leeching from the seals

It's just dirt from the frames that you have agitated. Do the frames over once and wait until they're dry, then do the glass only, job done.

Are you giving all windows a proper first clean as in a full and thorough clean of all the frames and glass, giving a good rinse of the tops of the frames to ensure you have removed all dirt. 

I have seen a good few lads just clean the face of the frame leaving the dirt trapped behind along the top the openers this will potentially cause dirty runs onto the glass. 

On first cleans dry all top frames off before rinsing.

I do this by putting a microfibre towel over the brush head.

It’s more likely than not a technique issue. 

How long have you been wfp? My guess is your pretty new. 

When your cleaning the too frame and top

seal, you get used to seeing how the water beads up in the seal, and you can usually swipe them away. 

Also if your only only using a low flow then this could be causing it. Your not thoroughly rinsing all the dirt sway. 

Being thorough is the key, in particularly he first clean, and then using a good flow. 

9yrs pal,Ime going to get on the ladder and check a few from yesterday 

Sometimes you dont even see these marks as the sun isnt directly on the window, but now its winter and the sun's low it shines directly on the glass and shows up everything. Ive allways found it too be the rubber. I had one yesterday had too like silver runs down the glass about 3inch long almost like a snail trail i just put a bit of unger rub out on the brush and gave the top rubber a good scrub then rinsed off. Its probably there all the time but you never notice till its in direct sun light. 

The suns a pain in the ass. I pole my own windows and have a bad seal on my front window. Thought I didn’t get a drip this time round until the next day the sun was on it and was as bad as ever 

Seals or lead staining perhaps

Exactly same pal look perfect on a dull day and then when sun comes out there a mess
