Deep clean
Start with the wheels ideally remove them (Safely jack and axle stand)
clean the same way as body work below (iron remover / tar) and seal with a wheel wax
<- gives some idea of the amount of iron deposits on the wheel....
(use separate cleaning cloths just for the wheels you don't want to be dragging metallic brake dust all over the car..)
Whilst the wheel is off clean the arch out with a cheap brush (toilet brush form pound land is ideal and some basic kitchen type all purpose cleaner)
Over time Tar off the roads due to wheel fling and botched pothole repairs covers the lower areas of the car so a suitable tar remover is needed either apply to a dry car with a old micro fibre cloth or a cheap trigger pump bottle (you will find most tar removers soon destroy the pump) try to keep it off any black textured plastic if you can.... then either wipe away very lightly or pressure wash off (you might need to repeat this step until its all removed)
(i find Autosmart tardis works very well)
Then wash the car with hot soapy water again to remove any residue
Then get the car almost dry and on with the Fall out remover AKA IRON remover.....
Now this stuff is not skin friendly so eye protection and goves are advised (it does do damage to the skin so long rubber gloves are better than latex or similar)
this comes in a few brands....
CarPro IRON X
Bilt Hamber Korrosol
And Autoglym Fallout remover are all good (the AG doesn't change colour though)
again apply with either a cloth or spray bottle and leave to work but dont allow to dry out.....
it reacts with bonded rust particles and dissolves the ferrous oxide releasing the particles from the paint...
which due to the chemicals released when steel oxidised can cause clear coat failure and accelerate damage to the paint
you can see it bleeding (showing a reaction in this pic
This product ideally needs a decent pressure washer to rinse after....
Followed by another wash (you will soon get bored of this step) :devil:
no need to dry the car now as its time to clay the car......
This removes anything else stuck to the paintwork......

Then wash and dry the car fully getting as much water out the water traps as you can.......
