Hi guys, after rinsing on the glass for 6 months, I started to notice brush marks on hydrophobic glass. The difference from when I started doing this technique to now was that I was working slower (hot weather slowing me down!) I immediately rectified the problem by speeding up, and keeping a good head of water above the brush. I’ve also adjusted the rinse bar, so that it sprays higher. Do any of you guys use a certain brush for rinsing on? Or do you get the scissors out and trim the bristles at the top of the brush? Any help much appreciated. TIA

Mono filament brush.

to be crude if your getting brush marks then you need to revisit your technique - ive rinse on for years with several different brushes and not had this issue, but I wouldn't do it with a flocked brush

Thanks Darren. I do have a tendency to plod along, so you’re right about the technique issue. As soon as I worked quicker there was no issues. I have a bay window at home with hydrophobic glass, working quickly resulted in a perfect clean! Thanks for the help 👍

Gardiner Supreme stiff works for me.

Hot water, and 3 mill (larger bore) Jets.

Run the pump flat out too.

I’ve never been able to work so fast than I do now with this set up.

Thanks Jonny. I did slow down during hot weather, and it’s obvious now that slowing down has caused the problem.  I’ve also emailed Gardiners for brush advice, and getting advice from you guys as well. Much appreciated. Ta..

Hot, sunny weather isn't our window cleaning friend. I wouldn't be surprised if your problems are with south facing windows that get the sun.
I always remember a post from a cleaner working in Cyprus.  He said that they had to spray the glass first to cool it down before they started to clean the windows. If they didn't the water on the glass dried before the windows had had a chance to drain down, taking the dirt with it.

When it comes to rinsing, we have always rinsed off the glass unless the windows are high up. This came from the time when the Vikan Oval flocked brush was the most popular window cleaning brush, as there was little else.

Thanks Spruce, it is a learning curve for me, and I’m always conscious of where the sun shines on each house, and you make a very good point on south facing! Thank you..

In the summer months, our front windows take a real hammering from the morning to mid-afternoon sun. I don't think the plastic is top quality, either. If I run my finger across the top transom bar of the frame, I get a white power residue on my finger. When cleaning the window, the water absorbs this residue and promptly deposits this in vertical lines of white spots down the glass, which become visible when the water dries. It just means that I have to do the frames and glass first and then come back to reclean the glass when the top frame has stopped dripping. I can also just run the brush head's bristles up again the frame with the water off to remove those last remaining drips. Then wash and rinse the glass only, not splashing water onto the top frame.

This does take time. Someone recently suggested that when doing a quote, just do the finger test before quoting. I thought that was a brilliant suggestion. Cleaning my type of windows will mean you quote a higher price as the job is going to take longer.

I've been cleaning our front windows for the past 18 years, and the problem has never got better.

Another point is that a couple of south facing windows on the round mist up when we clean them.  I had one on Friday.  The window has blown and let in moist air. When the air gap is cooled, it can't hold as much water vapour as it could when warm, so it releases it onto the glass.

That’s interesting about windows misting up when you clean. I have a few of those too. I’ve never given it much thought, but had wondered if the customer ever tried to blame me! At least I know the reason now. Cheers 👍

Gardiner Xtreme sill 35cm mixed unflocked with four 100 deg fanjets. I suspect rinse bars make the job harder than it needs to be.  Twice over every bit of glass then back to the top and chase the water down the glass. Flow rate 80, roughly 2.5Lpm.

Cheers Vin, I’ll take all advice on board, and spend a bit of time and money, and experiment . Thank you 🙏

Not sure if this is going to be new for you.
But I always rinse on glass.
I use a swivel and have the brush vertical, pressed against the window at an angle so the jets are hitting the glass and not having the bristles touching the glass. Move it left to right. I will upload if I have one, a video of what i mean.

That’s very good of you M Clean. Thank you 🙏

Do you have a works email. I can't upload it.

Interesting.

Think I will stay put with  6-18" radial ultra-lite brushes

Thanks for that. Plenty of different techniques.  I guess I’m experimenting this weekend!

My opinion. I would scrub the glass vertically rather than horizontally. I would also adjust the brush head to be pointing down more to be able to scrub the window sill.
