I've had a bit of success by mixing a concentrated brew of truck wash.
Mix in a cheap garden pressure sprayer, spray on and leave. Doesn't matter if it dries. Then pressure wash off.

It does not matter how much runs off, you just need to spray enough on to wet the surface. Wet the surface a few times and let it dry each time. After a few applications, then use the pressure sprayer.

If it's WA red iron oxide stains I use aluminium cleaner from the auto
shop. Also good for cleaning nuggets. :)

We drove a Mini from
Adelaide to
Darwin in 1967.
Margaret still has Tupperware from that trip with ground-in red stains.

Sadly, I expect the Mini would have gone to the smelter long ago. :(

Have you tried Vinegar? ie ACETIC ACID ! It removes calcium scale and other natural scale from surfaces and might work ok on the stain associated with earth staining.

I wouldn’t be using anything acidic. Maybe some truck wash and a pressure hose. Red oxide stains are OK.
Cheers

Truck Wash is acidic, that is why it lifts the dirt off. Most if not all carpet cleaners are slightly acidic too. If not, they don't clean carpet
well at all! Any secondhand car whose engine bay is clean and nice has been washed with a hydrochloric solution.

I’ve found CT 20, whilst harder to source is the better option. Less acidic, it also contains inhibitors and a wax which polishes up
well

As
well as Chemtech CT-18, (DON’T leave it on any gloss surfaces for more than 1 hr!) there’s these other 2 products that have good reviews.
Works well on chequer plate alloy, Ive seen the results.
Available at the big
green shed. My BIL swears by it!
The Red Stuff.
Bought
mine from local hardware, also available online. And anyone that has
bore water scale on their windscreen, get some FINE or SUPERFINE steel wool from your hardware or the BGS.

G'day Bob.
I see it says Don't Swallow, fair enough, but just "Gargle Only" I presume. It probably cleans out pipes too.
