I bought one of the Aldi platforms which I haven't had a proper chance to use yet, maybe I'll have a good go with it when the weather improves a bit.
Brissle, have you thought about a
telescopic ladder which you could place in the boot of your car when you go away?
With a short 3.8 metre (non telescopic in my case) ladder and my long handled extendable hose brush I get SWMBO to steady my ladder at our storage site, and can stand on the top but one rung to reach all parts of the roof if I approach the job from both sides, and I'm only 5'3" on tiptoe :lol:
To clean bird poo or general road gunge from the roof and skylights I put some neat
Fenwick's Caravan Cleaner into a bottle with a trigger pump and squirt it over the pre-wetted area to be cleaned, including my solar panel and rooflights.
I agitate and spread the Fenwick's with the dry brush and leave it to stand for a few minutes to loosen the grime and bird droppings.
While the cleaner is standing and doing it's stuff I move along to the next section to do the same, and so on for three sections each side, with the jockey wheel wound for the water to run off the front or back of the caravan.
When I turn the hose brush to spray the grime etc comes off quite easily with no clambering about to potentially damage the roof. I must confess that I've never actually polished the caravan roof, I use Fenwicks Bobby Dazzler sprayed onto the roof to provide a smooth clean surface and I wax the front back and sides of the caravan to preserve a great shine on the areas that are always visible.
