Anyone else get this with using wfp (I use clx22) I’ll be cleaning the windows then when coming to rinsing them down I see a some specs of like grit/diet on the glass that you need to rinse over a few times to wash off

This often happens when your brush is dirty.

If you've done a first clean, or a particularly dirty building, it's necessary to wash your brush to get rid of all the dirt.  Also needed when finished doing a spider web house (we all know them!)

My preferred method is to simply run it under flowing water (eg the port on your van) while brushing the bristles through with a washing up brush like this:



Use the bristles that point outward at the front to slide in between the bristles of the brush.

You don't need to spend ages at it, 2 minutes will make it as good as new.

We are on the North Coast and this is an issue with windows facing or very close to the sea. We also overlook a bay where ships anchor before being given clearance to enter Teesport docks. (TBH the grit and sticky residue on the windows isn't as bad these days since they built 3 rows of wind turbines off Redcar beach. The ships have to anchor further out now to stay well away from them.)

Sea spray together with ship's exhaust pollutants seem to leave a sticky, oily residue on the windows which attract grit and salt blown in on a North Sea wind.

We also live close to the old ICI Wilton chemical works so who knows what they pump out into the atmosphere.

I used to work for Bosch in South Africa. On my first visit to the Leinfelden HQ and manufacturing plant in  southern Germany, I was informed that they blamed ICI Wilton for the death of the Swabian black forest.

These days they seem to do most of their burning off of gasses at night. In winter they light up the night sky. One can only wonder what we are breathing in.

As has been mentioned, its easy to carry over grit on the brush from the previous window's  dirty window sill.

Some windows are worse than others. We found that running our fingers across the bristles with a water flow does help clean the brush. We do this very often.

I find it especially bad following high wind periods. Tons of debris collects in cobwebs and on ledges from nearby trees which get in the bristles of your brush. Like spruce, I'm constantly running my fingers over the brush to remove the excess muck, but sometimes a good rinse out under flowing water is also needed.
This for me, is where using a high flow rate really helps. (2-2.5 lpm at the brush head minimum)

dirty brush or very dirty windows.......or both......its part of the job....all you can do it regularly run your hand through your brush to get rid of the dirt,work with a high flow and use a mono brush NOT a flocked brush as they hold onto the dirt a bit more.....

 Nearly every job i do, i constantly check the brush for muck and run my fingers through it with the water flowing
 to clean it out, or otherwise its going back on the glass i find.

Cheers for the replies guys, I believe it is dirt from first cleans in my brush, I have been running my hand through the brush but it isn’t getting it all out i will have to give it a proper wash, cheers for the tip Pete Thompson I’ll be trying that method

No problem!  I actually discovered the washing up brush method by accident while at a customer's house.  Brush was dirty, and I used their outdoor tap to start washing it.  As it happened, there was a washing up brush laying next to the tap, and bingo!

I couldn't believe how easily and thoroughly it cleaned the brush, mainly because the bristles can slide in amongst the WFP brush bristles and get all the dirt out.  I have one (and a spare) in the van at all times now, and use it about 3 times a day.

Alternatively, as mentioned, you could just run your hand across the bristles or on a job I would use the middle frame on a window etc and run the brush over it a couple of times. This is OK, if it working from a trolley and you have a good water flow to rinse all the mess back off.
Yet the main thing I use is a clean microfiber cloth (cheap as chips from pound stores etc) and I keep it in a pouch, well two actually.  A slightly wet one for cleaning the pole hose (often throughout the day) and another to run over the brush instead of the hand.

I use a comb for flicking cobwebs and grit out - small, simple and does the job - no longer needed for fixing me syrup 

[Dave Willis]

I’ve had the same comb for forty years. Unfortunately I can’t part with it these days.
