cleaning off bull dust stains

Try Armorall on the Vinyl,worked for us.

A mate of mine used to use a concoction of hydrochloric, sulphuric, and hydrofluric acid that was popular as a treatment for aluminium before welding. Hydrofluric is used in concentrated form to seperate diamonds from almost any other mineral in existence. It used to kill people who were careless enough to splash some on the skin. I dont think you can get the concoction anymore for above mentioned reasons unless you are a specialist. My mate suffered badly from the effect of the fumes alone that got into his hands. There is a gel that fixes it but it took a long time to convince the medicos to give it him.

I know this dont help much but some of you might be interested in the story anyway.

In my experience the dust weathers off with time but you could source out someone who is reselling mining vehicles that come from the pilbara or similar landscapes.

happy scrubbing

Truck Wash & a gerni....works for me.............

Magic soap, water and a light scourer

It's a bugger alright - don't start me on the Pilbara - the hot dip galv is porous far as I can see - the dust gets in and goes rusty ! I scrubbed mine with a quality cream cleanser from the supermarket (JIF etc), using a pack of budget green scourers. Rust neutralising solutions are good too apparently, but I guess you have to guard against even minor spills elsewhere on the camper.

It won't help you now but once you have it cleaned.
There is clear coat (2 component) which you put over
prop plate (checker plate) or any rough surface which is hard
to cut and polish. This includes roof racks, ladders etc.
once this is done the dirt will wash off with a hose.
Manufacturers just don't think someone would actually use
their product for what it was made. Otherwise they would
take care of it.

good luck

NapiSan made into a thick creamy consistency and brushed on with a toothbrush or similar.

hI,

There is a cleaning solution called RIO, available from commercial cleaning suppliers, lived in Broome for 10 years and everyone including myself used to use it to remove the red pindan stains of there vehicles, is the ducks nuts.

These are some notes I took from a similar thread some months back.
(Yep, going to Kimberley and Pilbara again this winter!)

To remove Red Mud stains from Camper Trailers.
"alu-clean by cyndan is what to use. 40-1 mix with water & scrubing brush comes back like new"
"I have used a product called CT18 by Chemtech for years. Works on all types of surfaces and is does a great job. The longer that you leave it on, the better it works."
"I will try the CT18 by Chemtech mentioned above to see how good it is. I use Ranex (do a Google on it) Basically the red dust is iron oxide and the Ranex is Phosphoric Acid - I water it down and brush it on and hose off - cleans it like magic"
"As Trekkie says, it is iron oxide, which is in effect rust. So, it gets in the small pits in the surface and the discolouration will be there until you wash it all out. "


have fun!!!

Davidjo,

Just wear it with pride mate - it's a good look. Shows you've been to all the places that the shiny ones are still dreaming about. LOL.

It's always amusing to read the off-road caravanners agonising about how to keep their chequerplate bright and shiny.
