If you are having trouble cleaning brake dust off it's usually because your allowing the dust to be baked on from heat from braking process.

Do you clean your wheels regularly? e.g. every week

It helps if you clean regularly whilst not allowing the dust to settle on the wheel for too long.

Painting the wheels black or grey helps to hide the dust but it still will be there and again will bake on if you leave it too long.

My daugher washes her Mini once a month if that and I clean mine once a week on average and she has the same problem on her car... Brake dust in baked onto the wheels (especially the fronts) where I use a non acidic wheel cleaner (Bilberry) to try and shift it. I don't need to use it on my car due to regular washes.

Forgot to mention, I read that there are some nano coatings (e.g Gtechniq C5) that can be applied to wheels that leave a protective layer so that it's not so easy for brake dust to settle and dust is suppose to rince right off...

Not used it myself though so not sure if it really does what it says on the tin

Cheers mate. Yes I'm guilty of leaving it go for about three to four weeks depending on my shift work.
No doubt I should be cleaning it more often. I wonder if a wheel cleaner would be better than an iron fallout maybe ?

Iron fall out is normally used on bodywork where small iron spots end up on the paintwork and this removes it.

Not heard of using it on wheels to remove baked on brake dust though so can't vouch for it... Wheel cleaners (used with a small brush to help agitate the cleaner on the wheels) are designed for this type of work but be careful of acidic types which if left on too long or not rinsed off thoroughly can leave yellowing stains on your alloys.
