Description

Chemical Guys Decon Pro Iron Remover and Wheel Cleaner (SPI21516SW) is the professional-grade solution for removing stubborn brake dust, iron deposits, and road grime from wheels, calipers, tires, and exterior surfaces. Over time, vehicles accumulate microscopic iron particles from brake dust and industrial fallout that embed themselves into paintwork and wheels. Decon Pro dissolves these embedded dirt safely, restoring surfaces to a clean, smooth, and showroom shine. The advanced Chemical Guys cleaner formula is engineered to target iron particles that ordinary washing cannot remove. When applied, the cleaner reacts with iron and brake dust, breaking down the bond and dissolving the light debris. As it works, the solution changes color to a deep purple, visually demonstrating that iron particles are being safely lifted from the surface. This reaction ensures thorough cleaning while giving you confidence that embedded dirt are effectively removed. Safe for use on painted wheels, clear-coated rims, calipers, and most exterior surfaces, Decon Pro is trusted by professionals and enthusiasts to achieve deep-cleaning results without damaging finishes. The product is a great addition to your car detailing supplies. It's ideal for preparing vehicles for detailing steps such as polishing, waxing, or ceramic coating by ensuring that all grime and light debris is eliminated. Application is simple: spray onto cool wheels or surfaces, allow to react and change color, then rinse thoroughly with water. For heavier grime and light debris, agitate with a brush for best results. Whether used during routine wheel cleaning or as part of a full degrime and light debris detail, Chemical Guys Decon Pro Iron Remover and Wheel Cleaner ensures surfaces are spotless, smooth, and ready for protection. This wheel cleaner spray is great for car owners and auto detailers to use during paint preparation and vehicle maintenance. It offers easy detailing and dissolves brake dust and dirt.

  • Good wheel cleaner.
I bought it to remove brake dust that was caked on from winter. I followed the directions and I got good results. Not perfect, that took some extra scrubbing. Overall as it worked very well. Note: I have aluminum wheels

  • Works great, wear gloves
Works great. Wears gloves because the smell is strong and will linger on your hands. Depending on the vehicle, you might use half a bottle in one go.

  • Little on the spendy side - will do 4 wheels twice
This is a great product. No denying that, it works great on wheels, spray it on and you see the gunk turning purple right away. Easy to use. However, I was only able to get 2 uses out of 1 bottle, so a little spendy for the amount you get. Would like to see a bigger bottle or refill offered to purchase. great stuff though, cleaned my wheels quickly and easily. ... show more

  • Item arrived in a broken container
Updated September 2023 I contacted Chemical Guys and they sent me a replacement for the damaged bottle. The Iron remover works great. I highly recommend you use this outside or a well ventilated area. The remover smells like rotten eggs. Most iron removers I've used have the same odor. Glad that Chemical Guys came through and made things right. I have always had a positive experience with all Chemical Guys products. The only thing I can knock them on is how their products are packaged. It is not uncommon to receive a product that is somewhat damaged during packaging or shipping. Usually it does not keep me from using it. This time I was unable to use the product. The shrink-wrap was so tight, that it broke the nozzle and bottle. If you have ever used a Iron Remover you know how bad it smells. I have reached out to Chemical Guys for a replacement. When I receive the replacement I will update my review. ... show more

  • Actually did work.
Really rair, did everything they said. 😉

  • Waste of Money
Sprays on easily. Turns purple as it is exposed to oxygen. That's it. Basically , does not work as described. However, it does tend to soften the upper portion of caked on brake dust allowing you to use a scratch pad to dig it off.and spray the next coat and more intense scrubbing. Used as directed on a wheel this stuff doesn't even remove the ordinary film of road dirt that a wheel collects on a rainy day. Very disappointed due to the high cost of this product. Too good to be true applies . ... show more

  • Works like magic
I was afraid that I was going to have to replace the rims on my Audi S5 convertible. They look stained and straight with black gunk all over them. I tried other Will cleaners, and nothing worked even with a lot of elbow grease, rags and brushes. I literally sprayed this on waited 3 to 5 minutes And with a little bit of elbow grease and a terry cloth towel, I was able to clean my four wheels and probably about 30 minutes. They are not actually as clean as I will get them within the next application, but I only have a little bit of time to work on them today and I really didn’t expect it to work at all. I used about half of a bottle so I have half a bottle left, but hopefully They won’t be in as bad as shape as they were this time. I will definitely re-order and I cannot recommend this enough. ... show more
