I use a telescopic window pole from Aldi, then bend the brush section over your knee, then you can clean the roof from the floor.

If its bad I spray the caravan with poorboys snowfoam and caravan cleaner mix (I like auotoglym), then brush and wash off, starting from bottom to top.

Good advice until the last line - "bottom to top" - on a roof???:ph34r:

 

Seriously though; I've always believed that providing a good quality polish has been used, then plain water is normally all that is needed to restore the shine to a caravan roof. For the last 30 odd years our caravans and motorhomes have all been stored to the side of the house but it's embarrassing to see a dirty roof when viewed from the bathroom window above, so while the caravan was kept well polished and rinsed regularly with plain water, our MH tends to be cleaned with a mild detergent as the rubber membrane roof covering does not take kindly to polishes.

Can't comment on the soap sticks, but I hope the video below may inspire you.

I have a VAX pressure washer with extension poles, I attach 2 of these poles to the trigger and then the rotating brush head, cleans the roof very easily, then I use the soft brush attachment for  around the roof lights.

 

If it's very dirty I spray Snowfoam on beforehand.

Won't the ladder with weight of the guy damage the awning rail?

Actually,  no it won't and  I've done for many years.   You can put your fingers between the ladder and rail without causing injury.

I would be reluctant to use snowfoam unless you planned to polish and wax afterwards. It is designed to move remnants of polish etc from bodywork, or at least that's my understanding.

 

When I got the van 18 months ago it had a serious coating of Collinite Wax, which still forms a good base today. It will probably need another doing at some point this year, on the wheels I used a poorboys rim wax.  

 

I have a decent size step ladder that means I do not have to lean anything on the sides of the van, then its a good mix of Muc-off and long soft brush and using the two bucket method and a hose pipe, once done I wrap a decent microfibre cloth (I do go through a few of them) around the head of the brush and use something like Autoglym Rapid detailer. Generally tend to find that once a year for the roof is fine at the start of the season and just cos Im me usually give the roof a soapy wash mid year. The rest of the bodywork I do in the same way and then just go over the van  whenever needed with rapid detailer which I find cleans up the van well as a waterless wash.   Have used the same method on all my little collection of classic cars in the past and have always been easy to keep clean and shiny.

 

As sad as it may be, but keeping all my things mobile clean and polished is my therapy!!

     22mm  Pipe insulation is the way to go, I've been doing that for several years and no damage to the awning rails.  Safer than wobbling about on step ladders.  I use a long brush and bucket of water then rinse with the hose pipe like Gordon.  I find it doesn't get very dirty if I clean it twice a year and it's easy to do.

Anyone used `Wet and Forget` on their van roof?

I`ve used it on pebbles, tarmac, PVCu window frames and fascias/soffits and it has always produced a better result than I expected.   Just thinking a quick blast on the roof will remove any crud and algae so making the post-winter wash much easier.

I did my roof last spring, luckily i had access to a large forklift i could climb up on the back of to reach, and some truck wash, and a steam cleaner/pressure washer, i set it up so the truck wash was being metered in as i washed it, wasn't exactly satisfactory, you can see where i tried that in the first image, so i changed tactics,  i spray bottled the roof with neat truck wash, went and had a cup of tea and then came back and jetted it off, came up lovely.

I would never use truck wash/TFR on my caravan.

I use it on everything, agreed it is quite aggressive, but as long as you make sure it's absolutely all washed away and get some protection back on surfaces afterwards (I use meguiars wax) I've always been ok.

I wouldn't use a TFR unless I wanted to strip the wax and start again, but I like snowfoam on the car as its gentle and removes the dirt before cleaning to prevent swirl marks.

I also use the 2 bucket method, both the caravan and the car have been treated with Boora Permaseal,  then Collanite 476 on the car and auotoglym on the caravan.

I use the Collanite 476 on the caravan as well, its brilliant stuff and then just wipe it over when I feel the need with rapid detailer.

I wouldn't dream of using anything as aggressive as TFR, does it not damage some of the through roof seals and gaskets?

There are different TFRs as well as different snowfoams, I use an economy TFR as a moss killer on paths, whereas I use a ph. neutral one for wheel cleaning.  As with all cleaning substances follow the instructions and don't be tempted to add another glug :)

 

Theres lots of info on detailing forums on which to use and which to avoid

Using a pressure wash you need to take into account that the seal are only non setting mastic and only soft and you could blast the mastic apart and create leaks into it . I only use a hose on a low pressure to wash any of my caravans or motorhomes .

 

What ever I wash over with usually a autoglym shampoo I then immediately clean it off the acylic windows with autoglym glass cleaner that is safe on acylic to stop crazing .

I would never use any product on my van that was not specifically sold for that purpose, not because of the effect on the paint, rather the effect on the sealants. Some products are incredibly aggressive and the last thing I want is a chemical attack on the joints.
