Pressure Washing

Post by shuttle on Sat Jan 25, 2014 10:43 am

I have a 2003 Nuevo unfortunately I have to park it under a tree resulting in it being prone to green algae .My question is can I pressure wash it using a low setting .I know not to do the windows,louvre vents etc but cannot see a problem in doing the bodywork . There seems to be two schools of thought here, those that say yes you can pressure wash it and those that say do not .What do I do ?

A high pressure water jet can (and will) cut rubber, lift graphics and remove paint so must always be used with great care.  Only use it on areas where the finish is sound and original and never closer than 15cm to the surface.

In my experience I have found that the most effective way to remove green algae is with a good quality microfibre cloth and a bucket of water without detergent/soap etc.  You need to keep rinsing the cloth and you will have to change the water a few times but you only have to attend to any area once and its safe to work around vents, aerials etc.

If any marks remain after that then I would spot clean with a damp loth and Fenwicks motorhome cleaner.

Hope this helps.

Hi i agree again with Peter.No easy way.  Jet washing can damage your graphics as well.
this year i am using a cover for the first time. Will see if any damage  caused by the cover in March.

I used the Fenwicks Caravan cleaner on my caravan (like you would ha ha) and was very concerned to find it turned the false chrome on the wheel trims green and chrome started cracking before aI could rinse it off. It's extreme strength although diluted exactly as per destructions worried me and I hadn't used it again. Is it a different chemical mix for motorhomes as I cannot see Peter using something too chemically aggressive?

It is the Motorhome cleaner I use. Quote from their web site:

Fenwicks Motorhome Cleaner - Safe for use on all motorhome surfaces

Fenwicks Motorhome Cleaner Concentrate easily removes streaks, green algae, road traffic film, diesel fumes, and over wintering grime, etc. It is suitable for cleaning plastics, aluminium, acrylic windows, GRP, ABS, fibreglass, decals, sealants and much more. Highly concentrated formula, guaranteed results.

Available in 1 Litre bottle

How to use Fenwicks Motorhome Cleaner

Step 1: Pour 2 capfuls of Fenwicks Motorhome Cleaner Concentrate into 5 litres of warm or cold clean water.
Step 2: Apply to surfaces from bottom to top using a spray, sponge or brush.
Step 3: Allow 30 secs to 1 mins to soak in, but do not allow to dry.
Step 4: Agitate with a sponge or soft brush.
Step 5: Rinse thoroughly with water from top to bottom, or for that showroom finish just add Fenwicks Bobby Dazzler to the rinse water.

Handy hints

1) A 1 to 10 solution will remove stubborn marks and black streaks.
2) Rinsing with Fenwicks Bobby Dazzler protects and makes cleaning easier.
3) If using a pressure washer, use a dilution rate of 200-1 at the lance end.

End quote.

I've had no problems with it.

I have had very good results with a new product from a company called mud-busters. [You must be registered and logged in to see this link.]

Hi, Don't use a pressure washer, I used one to deliberately strip off the graphics on our Clubman, and believe me they come off really easy this way. So I recon while you think the washer is on a low setting it will still damage the graphics.

Pressure washers are fine if used sensibly. As suggested don't point close range at graphics windows, roof vents.

Like most tools they are designed to make the job easier and save time, if you're careful you won't damage your van.
