TERSHINE RELIVE IRON REMOVER 500 ML
Always be careful on "home painted" surfaces (spray can, no clear coat, etc). It rarely tolerates chemistry very well! Of course, rims/brakes must be cold! Then if you have a car with ceramic discs, it's pretty much always enough to just run the high pressure and some shampoo. Biodegradable and contains no high fluorinated substances (PFAS)! Can be diluted with water, I don't have exactly what works best but do as usual, lab (but around 50/50).
