I worked as a HD detailer in the Pilbara for a year so I know more about cleaning than finishes... But here's my $0.02
But a mix of hydrocloric acid/sulfuric acid solution is ideal for removing all brake and red dust/ bore water mess, though be careful with it on stainless steel and alloys. Use lots of water and a light scrub. Never allow to dry on the paint.
Windex when sprayed liberally into roof/door/seat/floor carpets then buffed lightly will remove all grease, dirt/blood or other mess from the them.
We also used Citrus Green up north and it was a fantastic light duty soap and it had a wax solution in it too as a "conditioner" to the "shampoo" Best applied with a soft headed broom and lots of water.
