Stains on Volk Wheels

[pushtiulk]

Hi guys,

I have 4 Volk C28N wheels and on the winter some black stains appear that I can't remove with Sonax Full Effect. Can you help me with some tips?

Pictures attached (the wheels were cleaned during pics)!

Sincerely,

I'm wondering if a claybar would do any good.

It looks like mold!

Steam maybe? Might need a more aggressive chemical.

Possibly pitting due to salts and or acids.

I've tried with claybar and nothing. If it's pitting from salt, what can I do?

If you can feel an indentation, or use a toothpick or so to see if it snags, then pitting is your problem. If not seek another solution.
If its pitting, only recourse is stripping off protective barrier ( clear coat or poly film) followed by sanding and refinishing.

Iron X Gel.

That sure looks like pitting. Stripping and sanding is what I would do. Then repaint and clear-coat.

I get similar spotting on the wheels of my Mini. Although mine isn't pitting but rather the ferrous material of the brakes embedding into the aluminum wheels. Iron X and clay bar gets them back to normal. Lne of these days I will seal them with some Opti Seal to slow this down.

Iron X is much stronger than Sonax Full Effect? I've tried with Full Effect and claybar and nothing.
