Power washer

They are the quick way to get water ingress in leisure vehicles unless much care is taken and they can strip vinyles  in seconds

They are absolutely brilliant at removing sealant from joints. 

Used with care, they are fabulous labour saving devices and can be used on roofs. I use a Karcher.

 When I had the "Autocruise" I did the roof first with a patio cleaner and a broom,then rinsed with a bucket of water and broom.Preasure washers in general are bad news for our vehicles as said . 

I've got a Karcher - brilliant for stripping the dirt from the pavers on the drive and cleaning the timber on the patio but I wouldn't recommend using one on a Motorhome.

The water will strip away the decals, sealant from the joints and you can guarantee it will find its way up and into the fridge/freezer vents and soak the gubbins inside - and roof vents are particularly vulnerable.

And taking MH to a Car wash and letting them speedily power wash your vehicle is a recipe for disaster.

Do it the time honoured bucket and sponge way for peace of mind and less chance of damaging the MH.

 

Just don't. Not worth the risk in my book.

We've used a Karcher on our van when we 'snowfoamed' the vehicle from the roof downwards. It took so long to do because of the need to stay away from seals that we've never bothered again although the van came out a treat.

Your manual may comment on how to clean your van and if your van is still under warranty, using a pressure washer is a good way of voiding it.

You may have the message power washers are not good ! However I use one purely to drive a snow foamer, not for rinsing down. You will find a light wipe with a sponge removes dirt better than a power washer on a polished surface.

I use Fenwick products for mhomes, as the cleaner is formulated for materials used on them. Not many cars have vinyl decals, acrylic Windows and loads of sealant and maybe specialist body panel materials.

I have a 8 metre long , 3 metre high mhome, so takes a bit of cleaning.

i work a side at a time, starting with the roof. Luckily I have a tall step ladde that I can use a long washing brush to reach over the roof area.

i snow foam using Fenwick cleaner, let it sit for five minutes, then scrub off. Rinse off, then use Fenwick Bobby Dazzler as a final rinse, Then I repeat on each side. A wipe down after using Bobby Dazzler, with a micro cloth leaves a decent finish (until the next road trip ,)

Depending on the manufacture recommendations , a silicone free polish and wax may be required to finish off. (Marine chandlers are best source for these items)

Ok, thanks all for the input. Glad we asked the question!

Its the roof we really wanted it for but will avoid using the washer for the vehicle at all. 

Any tips on how to clean the roof, is a step ladder sufficient? It a 3m high van (elldis 185).
