Review on 🚀 Optimum (21977) FerreX - 17 oz.: Ultimate Iron Fallout Remover for a Flawless Finish by Tony Weber

First off, when this product smells less like rotten eggs than other brands of iron and sludge remover, I'm afraid to try others. Sprayed the car with Ferrex after washing and rinsing. At first I wasn't sure if it works or not, mainly because of the dark gray color of my car. In fact, after a minute or two I noticed the ground around my car turning purple, which indicated to me that Ferrex was activated and working on my car. The attached picture was taken before I washed the Ferrex off, it's just drips running down the paint. My only issue was that I used almost the entire bottle on my mid-size sedan. This could have been avoided if my car was a different color and I could tell where the product was applied rather than potentially over saturating. Otherwise a good product.
