Undrdog’s The Purps Iron and Fallout Remover does what it is supposed to do. After spraying it onto the car, the iron is worked loose from the car’s surface and allows you to rinse it off using water. It does the job well, and I don’t have any complaints about the product.

I’ve used Adam’s Iron Remover for almost a year now and have been pleased with the results I’ve had. I’ve used it on a number of vehicles ranging from a vehicle that has never had a chemical decontamination for more than a decade to a brand new vehicle. It does what its supposed to, which is to assist with removing ferrous (metallic) contaminants on your car’s paint.

Regardless of whether your car was maintained well or poorly, it is always wise to perform an iron decontamination (along with a mechanical decontamination) as preparation for a wax, sealant, or coating. The reason for this is that if you are going to apply an LSP (last step product) such as one of these mentioned, you don’t want to be sealing in any iron contaminants, which could continue eating through your paint. If you ever plan to apply a protective wax, sealant, or coating, consider doing an iron decontamination with an iron remover.
