Pro-Kleen Dragon's Blood Extreme Fallout Remover 5L – Ultimate Iron Contamination Cleaner for All Wheel Types! Super Concentrated, pH Neutral Formula – Perfect for Alloy Rims, Paintwork, and Glass

Works really well - not only on wheel but also effectively cleans alloy brake caliper and hub.

As you can see from my first picture my wheel is heavily contaminated. I didn't expect miracles and I was fully expecting multiple applications to even make a dent it. The second picture is after 1 application. Not perfect but miraculous in just how much cleaner it is. I can even see some kind of black paint or something the previous owner applied. Very easy to use... I painted it on with an old brush and agitated it with a green scrubber from the kitchen. It does have a horrible smell but not that noticeable if you use it outside. Another application... maybe 2 and it'll be a wheel thats no linger a total embarrassment. Very impressed.

Expensive investment but well worth it and it works as expected. Wear safety goggles and don't huff the fumes as the product does stink. It is a low viscosity liquid that sprays and doesn't clog a spray bottle unlike other products which can have a very high viscosity and are more like gels, this product gets into nooks and crannies instead of clumping up in one area and after sitting for a minute or two in high humidity I feel that the product did a fantastic job - on par with more expensive iron decontamination products i've used before. It was nice to see one of my rims looking so brown and caked in grime/brake dust actually just be road grime as the expected blood bath wasn't as bad as I thought it would be, now my rims look nice again.

does what it says it will and works well it smells a bit rotten eggy

Good product, not gel like my previous nice smel

this does a job but not as good as some other makes, but to be fair its half the price so......... easy to spray on, leave it work but not go dry. I agitated with a brush on a drill and blasted off. Wheels came out nice but a few places really needed a second coat. Bilstein works with one coat!

Great stuff, great value, decant into smaller bottles and save a significant amount of money!

Powerful wheel cleaner, even my callipers and the bit of disc between the wheel and hub which is normally rusty is now shiny steel like new. Would definitely recommend trying it
