Brake gunk on my alloys - help!!

Hi all,

Just tried cleaning my alloy wheels today and found I have a problem. The front wheels have streaks of a dark gunk over them that is very hard to remove. It does come off if you scrape hard with a fingernail, but using this method it would take many, many hours to remove. Any ideas on an easier way to get my wheels back to their usual pristine condition? I am using Megs Hot Rims as the usual cleaner but it has virtually no effect on this stuff. BTW, I just had new brake lines and pads fitted so it's some kind of fluid conected with that.

Cheers,

Nigel

Brake dust can be well baked on, if you leave it over long periods. Veggie based brake fluid will attack paint and lacquer finishes, but I doubt if that is your problem?:

Try some paint restorer polish from somewhere like tesco. Yes it might take a while. You could also try a green kitchen scourer followed by polish on the wheels which have a tough finish but take it easy so you don't damage your wheels.

I have found that the dust on the new PF pads is quite aggressive compared to standard stuff. Left for 3 weeks it was well hard to get off. Resorted to peek / brasso followed by a good silver waxing. Elbow grease with a mild abrasive metal polish is the only way forward followed by a good waxing to make the job easier next time.

Re: Brake gunk on my alloys - help!!

Did anyone ever fit those flexible dust excluder discs, that were available to fit on the inside of their wheels? I wasn't too struck on the idea, but I suppose they were effective enough?:

Re: Brake gunk on my alloys - help!!

Glad you said that, because that's exactly what I thought, they looked crap, and would of restricted the airflow around the brakes and hubs.:

My laborious method is after a journey, wipe the wheels with a paper kitchen towel, on which I have applied a drop of the old mixture. Stops the build up of brake crud too.:

Re: Brake gunk on my alloys - help!!

Thanks all, lots of good advice. Simon, I suspect it's dust from the PF pads that got "washed" onto the wheels when I was bedding in the pads while it was a bit wet. Happened a couple of weeks ago, I was away all last week on business so have only been able to get to it just now. I'll try some mild metal polish per Simon's suggestion.

BTW, what do you use to wax your wheels? I've been using a brake dust barrier product. Would you recommend a hard wearing wax like Collinite instead?

Cheers,

Nigel

Re: Brake gunk on my alloys - help!!

I just use the same wax as the car (zymmol).The aggressiveness that you have too use for the wheels would probably take off any kind of wax so no point in shelling out foe more.

Good news - with green kitchen scourer, Meg's Hot Rims, Autoglym Intensive Tar Remover and lots of elbow grease I managed to get all the stuff off. Took about 2 hours

Thanks for the advice all, now have to give them a good wax.

Cheers,

Nigel

3M Imperial Hand Glaze will shift stubborn marks on your wheels. It's a gentle polish so it'll leave them with a nice finish aswell.

I used the Autoglym Alloy wheel spray wax, does a great job and make cleaning really easy. Likewise any good polish and wax applied to nice clean alloys will help prevent dust build up.

Anyone else used "Wonder Wheels" I use it every month or so... real easy to apply with a brush and gets rid of everything cruddy.

Not a fan of wonder wheels - too agressive. Use Autoglym trade acid free wheel cleaner

Wonder Wheels is agressive, but it does the trick.

I only use once in a blue moon, then protect with Poorboys Wheel Sealant...so it just wipes off.

Re: Brake gunk on my alloys - help!!

You know what I find is really good for getting off brake dust, Tesco's own brand vinegar, and a scourer. Apply the vinegar in quantity (only 14p a bottle), leave for a minute or two and all but the most stubborn marks will come off with a sponge, otherwise you have the scouring side..

Doesn't it make your car whiff a bit? I suppose it means you can bring the fish and chips home without any worry.

Seriously though, sounds worth a try. I like "natural" alternatives.

Cheers,

Nigel

Re: Brake gunk on my alloys - help!!

I recently used JML Doktor Power to clean my alloys, it's slightly abbrasive but seemed to do the job reasonably well and claims to be environmentally friendly. Reminded me of AJAX to be honest. I want to remove them and give them a good going over once I get a chance to give the car a full clean.

Re: Brake gunk on my alloys - help!!

Wonder Wheels is too Acidic - yes it'll remove marks but will also start to degrade your Alloy Laquer. Reccomended by Laptop in Brum who refurbed my alloys that the best advice is simply to wash over once a week with a bucket full of Hot water with simple washing up liquid in!
Does the trick for me.....
