Hi all,

Would anyone like to explain their own technique for rinsing on the glass with fan jets, and which brush they using.

Cheers

Hi Mathew,
I have stalks with the jets located at the top and end of the Monofilament brush bristles for rinsing at height, you could use the forum search button at the top of the page and use the word "rinsing" you might get a topic like this http://www.cleanitup.co.uk/smf/index.php?topic=102164.0

i use a SL DT Mono with fans, brush the glass as normal back to the top of the glass rinse as you would with the brush off the glass.

I have a SL single trim mono with 60 degree fans and the centre row of bristles removed . I go sideways across the top plastic bit of the window and top seal  then  I go up and down enough to cover all the window and side of frames and then sideways covering all the window. I don't really regard that as a  rinse, but it works for me.  I have a 2 litre flow rate I think that is very  important. I used to do the same with SL mono dt with pencils with no problem.

But about 2 and a half years ago I was using a blue bristled Salmon autobrush with fans. I NEVER received  any complaints but I did notice  spots a few times although  I never normally check work  and so was never confident with it.

Hi Matthew.

Whichever brush you use, the fewer bristles touching the glass, the easier it is to rinse.

For the last two years, I have been using a Gardiners Superlite Dual-trim Brush with fan jets, fitted by me.

I have found that the easiest way of rinsing is to take the weight OFF the brush-head and let it 'scim' across the surface of the glass while you move it from side to side. In other words - only the uppermost bristles are touching the glass.

It is important though, before starting to rinse, to thoroughly wet the complete surface of the glass (not easy to see, sometimes, from down on the ground) - using plenty of water along the top edge and in the corners.

Gardiners Mono DT with fans 40 deg  and the other with 60 deg.

pretty identical as miles - run brush over frame above window then top edge of glass, scrub over all glass area
returning to top sweep across to finish - fan and high flow means i get a good curtain of water with the final sweep
- brush on glass all the time.

Ok thanks guys,

I am trying gardiners SL Mono single trim at the mo with 2 rows of bristles removed below the top row, 40 degree jets spaced either side of the stock attachment.

For my rinse i lightly trail the brush taking the weight off like you said first down each side of the glass/frame, then across the top of the glass with a light left to right motion back down.

Am thinking about fitting a brush with fan jets at the very top by removing the top row of bristles so the jets are outside of them, you could then sweep the brush down the glass, and the last thing that would touch is the water from the jets - similar the the ionics overhead commercial fan jet attachement.
Do you think this would work well ??

Still finding nasty hydrophbic glass that the water beads badly on though, and its these windows that i sometimes worry about - but no complaints in 8 months.

In my opinion, if the glass has been cleaned properly, lightly skimming the glass with monofilament bristles isn’t going to have any detrimental effect on the cleanliness already achieved.

Although some brushes do have the jets above the bristles, personally, I don’t think it is a good idea. Fan jets are quite powerful and the spray can travel some distance, if not contained. The top row(s) of bristles do the containing and prevent dirt from outside the cleaned areas being dislodged

Hi Mike,

I would agree with that, the bristles being used to contain the spray from the jets.  If a window is being cleaned regularly with WFP say every 8 weeks, i think in some cases you could get away without rinsing at all and still get a good finish, although i wouldn't take that small risk on customers, i may try this on my own windows.

For me i don't want to spend any more time than i need to on any regular windows, and that means the quickest technique possible without compromising on the cleaning standard on any of my customers windows, so i value all others input into this.

Are there any outside scenarios we can think of where you could not rinse on the glass ?

If you are using monofilament bristles you are rinsing the dirt away whilst you are cleaning – because the water, and loosened dirt, drains through the bristles throughout the process.

Rinsing IS a waste of time if the windows haven’t been cleaned properly.
If they HAVE been cleaned properly, rinsing MIGHT not be necessary - but I wouldn't risk it.

Personally, I concentrate on the CLEANING, with particular attention given to the tops and corners. After that, I find that a QUICK sweep from side to side (starting at the top and zig-zagging down to the bottom) is all that is necessary.

A word of warning, however, from my own experience:

Sometimes, windows don’t LOOK dirty at all and it is natural to think that a quick operation will suffice. On such occasions, I always have a quick look before leaving the premises and have been surprised sometimes to find that I have needed to re-do some of the windows (properly the second time!), so that in the end, I didn’t save any time at all (probably took me longer!).
