Why isn't the colour change as intense as Ferrous Dueller?
It's a broader formulation with additional cleaning agents, so the reaction is slightly less dramatic but more comprehensive.
Will it remove all tar spots?
It helps soften them, but stubborn or baked-on tar will need a dedicated tar remover.
Is it safe on all wheel finishes?
Yes - pH-neutral formulation is safe on all wheel types.
How long should I leave it on?
A few minutes until the colour change is complete.
Can I use this on paintwork?
It's formulated specifically for wheels - use Ferrous Dueller for paintwork iron removal.
What makes it better than cheap colour-change cleaners?
Full-strength active ingredients and additional cleaning agents for superior results.
