Brake disc surface rust cleanup.
Discussion
I have some new discs that have a light coat of surface rust on them and I want to clean then up before fitting them.
I know if I put them on the pads will clean the contact area but everything else will still have rust.
What can I do to clean them and what can I put on non contact ateas to keep them rust free.
Any help or advice much appreciated.

I used one of these

They're designed for removing surface rust without damaging the metal surface

I’ve replied on FB but I just lightly sand then with wet and dry then spray them with Hammerite satin black “smooth” but can use any colour you want , don’t need any prep as it meant to be used for this purpose (rust) and I do the callipers with this as well and have done on all my cars for many years never had an issue never needed special calliper paints etc (recently done mine few weeks ago)

Might be completely mis-understanding you, but are you saying you spray your discs in satin black?MRichards99 said:

I'm sure that TVRSJW will confirm this in due course, but I'll bet my last groat that he means only the bells, i.e. the parts of the disc not in contact with the pads....

For improved brake performance you could try the 'non slip' paint they use on boat decks or stair treads.
Not too far from reality there............... many moons ago working in a Ford Dealership, when solid discs were the norm, brake judder was a common issue caused by the discs "glazing" too much low speed gentle braking.Fords solution was some new pads, with a sort of lumpy abrasive paint on the contact face. This scrubbed up the discs then wore off.
In all seriousness if the OP just puts some cheap white vinegar in a plant sprayer and gives his surface rusty discs a quick huff over he can remove that rust without resorting to anything abrasive.
1. Spray the discs with the vinegar and let it sit for five minutes or more depending on severity of the rust
2. With some kitchen towel dampened with tap water wipe away the vinegar residue to neutralise it
3. With some dry kitchen towel spend a minute or two to thoroughly dry the disc so no future surface rust well return
You should also find this method will remove and oils on the disc you probably don't even notice is still there.
Job done for roughly 50p and you've used no aggressive abrasives whatsoever
I was shown this method years ago and long before YouTube, I prefer the plant sprayer and kitchen roll method although it sometimes helps to dampen the kitchen roll with the vinegar to make a kind of caustic compress as this holds it to the steel surface better.
Others it seems prefer vinegar the dip method, but at the end of the day however you apply it vinegar always does the trick, its safe, organic, non-aggression, highly effective and cheap as chips... No pun intended
Others use the full dip method it seems.

I guess this is something similar to what EBC do on the Green/YellowStuff pads to remove old pad deposits from the disc?Fords solution was some new pads, with a sort of lumpy abrasive paint on the contact face. This scrubbed up the discs then wore off.
