So A few of you know that I recently purchased some genuine alloys for my Jazz for a very good price that was with in my budget. They are nice and clean on the outside but inside is another story. As a few of you have already advised that Iron X will be the best solution to cleaning however 1. Iron X is quite expensive (~£15+) and 2. the more I read into it the clearer it becomes that Iron X is kind of a finishing off product and the condition that my wheels are in, I might need quite a lot of it so I thought maybe I do the heavy duty lifting with a cheaper product first. I would like to not spend too much cleaning them up as I bought the full set for well under £100. I have washed them up and used a cheap Triple QX wheel cleaner I had at hand and atleast that washed away all the dirt,grime and alot of brake dust however these baked on contaminants on the inside of wheels are still there. Before: After: I mean what is this stuff? There are some cheaper products mentioned on detailing world such as a. Bilberry Safe Alloy Wheel Cleaner £10 b. Generic Iron Contaminate Remover £8 which is apparently Autosmart Wheel Cleaner c. Wonder Wheels from CarPlan at ASDA £5 and has decent review on Detailing World. What do you guys think? @wanner69 I know you work with top stuff but can you advise of a budget product if possible?
