Wheel Brightener: Results

Unfortunately regardless if a chemical reaction releases heat in an aqueous solution, it is irrelevant to the ferrous portion of brake dust simply because the carbometallic compound formed with heat and oxidation was never a pure iron particle to begin with.

While it is the ferrous matter in brake material that initially causes such an eye catching reaction of going from green to red with the Sonax, the fact that there is a now a completely different compound to deal with adhered to the outer covering of the surface.

As shown by many of the write ups, Sonax is good for the non "reacted" dust as it not dealing with a bond between this hybrid particle formed over time from sitting, it obviously, as shown does not have significant effects on the hardened organometallic compound that has been roasted on and undergone its own reaction.

Again which is why wheels that have been left for extended periods of time with significant amounts of brake dust(which is now something that really isn't brake dust despite starting from it) show little improvement(except to the ferrous portion of the dust that hasn't reacted) with Sonax.

Obviously with the carbon build up one would think that a certain type of abrasion would be an appropriate answer as acidic and heavy alkaline wheel cleaners are designed to react with the metallic potion of the brake compounds.

 

We use sulphuric acid is used to prepare and clean carbon deposits from uncoated metal prior to fabrication. As you consider this method unsuitable / inefficient then what is your method/product for cleaning sintered metal particulates from a coated wheel surface?
