i did a conny roof today, i used "evans high class" detergent, same as i use for windows, then connected pole to custys hose reel. scrub and rinse with my new "vikan stiff sill brush" then finally gave it a quick going over with puer water.

one thing i was a little worried about after inspecting the finished job was i fear the vikan stiff brush might have slightly but hardly noticably scratched the polyerothane (plasctic corrigated) roof panels    

what do other recon?

Maybe they were always there and only noticable when the dirt had been removed OR you could have got some grit on your brush head and this has caused it to scratch.

Cleaning perspex with any sort of monofilamet brush will scratch the plastic/perspex, come back on a sunny day and look from the inside to see the crazing

really? oh dear 

On the plus side its like frosted perspects/plastic whatever it is, not totally transparent, so i hope the custy wont notice! 

one more question, what in the hell is this god damn vikin stiff brush good for then? i bought it for conny roofs now i cant even use it on them! might as well chuck it in the bin?!?   

p.s i know ive got this in another thread

Thanks mate

I use it for everything but reading your post has made me rethink, I don,t even own a flocked brush, all my brushes are mono whatever the make

@ stu mac...

no never noticed any scratching but I don't do a lot and don't push that side of things, as I said though your post has me thinking that it is not good, to be on the safe side I will use a flocked brush in the future on any plastic roofs, I did turn down a roof with an anti glare film on the outside because I read that it scratches very easily.

yeah i think i might start using my flocked sill brush that as never been used yet for these type of conny roofs! another thing mate...

are the clear normal "glass looking" conny roofs special in anyway? would my vikan stiff be ok for these? and how can you tell if its anti-glare/self cleaning or whatever? does it have this infomation printed on the glass like tempered glass does?

[mci services]

I don't know GB, I have always used stiff brushes on all roofs, to be honest I don't like doing con roofs of any kind and I am thinking of binning doing them altogether, more hassle than they are worth. Honestly though I am not the man to ask advice on con roofs, it would seem I am just as clueless as you on this subject.

  thanks anyway stu, lets hope i can get some more info on this thread for the both of us then hey! 

@ geff brimble, what do you think? you seem to know your stuff mate! 

[Jeff Brimble]

Times change, its an old topic, there are new brushes and bristles out there, maybe best if you do your own research on your neighbours red/black Ferrari and try cleaning it with your own monfilament to "see" if it scratches 
I think this scratches issue is why Tucker brought out a plexi glass brush for cleaning cladding/plastic, its dupont filaments do not scratch, I know cause I bought one for a £5million satin annodised building.

[L.Doubtfire - The Blade Runner]

Any brush,or pad or whatever you use will leave light scratch
Marks on plexi glass or window film tint that has been installed
On the outside of the glass.
It`s virtually impossible to avoid it.
Just stop and think a few seconds.The `conny`roof is covered in
Light dust,heavier soilage , bird mess here and there etc etc.
Although your agitating with water / solution it`s still gonna scratch.
I turn em`down.
You could end up with a claim for replacement `on ya lap`.

thanks folks, jeff, yeah good thinking, my girlfriend as a nearly new car so i'll try my mono brush on that hehehe 

But seriously some good info, and like you said jeff theres probably a bit of trial and error involved these days.
this "tucker" brush sounds interesting i'll give that a look. have you got a link for it? or should i stop being lazy and use google? 

Many thanks once again, GB

[Jeff Brimble]

The brush is expensive but I thought for a £5mill building it was worth it as I want to keep the job. Get it from Aquafactors, no link I had to telephone them and pick it up at the show, its called a cladding brush and you may have to retro  fit it to your own pole system.But a bog standard flocked will do , liks a Bentley etc.

tar jeff, i'll check em out mate!
