Conservatory roof brush/jets

Hi

The last 6 months, I have slowly been transitioning over to using water fed pole to clean my customers Windows. I would like to start offering conservatory and pvc cleans to my customers, as I have had a few customers ask me now that i have the wfp setup.

My question is, what brush(s) and jets do you guys use/recommend? I currently have a 26cm sill brush, 26cm stiff brush and a leaded brush all from gardiner and I use 2mm pencil jets.

We use the same set up for windows , plastic , and all cleaning , we use Gardiners supreame brushes with 2 mm pencil jets , I like the longer bristles and stock  shape and the splay gets into all the corners . 

Whatever you feel comfortable with cleaning windows with should suffice. Usually longer the bristle the better the result, especially on fsg's

Thanks for the replies guys, I was leaning towards using the stiffer brush to help with the moss etc, I have never tried cleaning polycarbonate and I don't know how prone it is to scratching.

It would be nigh on impossible to scratch a polycarbonate roof with a WFP brush, no matter how stiff it is.

If you did scratch a polycarbonate roof you wouldn’t see them as most are opaque anyway .

The job becomes fairly easy if you use hot water and degreaser and scrub away. If there is a hose nearby then its perfect for rinsing.
