Every time I wash or wax my 991 and take it for a drive I find black brake dust residual all over the lower panels. Is there an easy way to remove the dust without rewashing the car and that will not damage the finish? Will a micro fibre cloth damage the paint? Can it be blown off with air? Any ideas would be appreciated.

 

Sure it's brake dust? Frankly I would never wipe a dry car.

 

What are you using for tire dressing? ....that may be what it is.

 

Not using tire dressing. Any suggestions? Thats what I thought it was at first but after posting a question here most said brake dust. Its black so I think its more likely from the tires?

 

As rnl stated .... I wouldnt try to wipe it off.

Post a pic if you can....I'm curious to see what this looks like when you say its "all over the lower panels"

 

Definitely don't wipe. If anything try to blow some of it off with a leaf blower. If your car has a nice coat of wax, some of it may come off.

 

I've noticed the same problem and didn't know if it was brake dust or bits of rubber from the tire. I tried wiping it off with a Kozak cloth and it didn't come off without applying a lot of pressure. I waxed the car to see if that would stop the dust from sticking to the finish. The slickness of the finish was much better when I waxed it so I had hope that it would work. It did help (see car side picture) a lot and even though there was some dust but this time the Kozak cloth takes it off like it was dust. I'm going to wax it again on the sides to see if it gets better. I suspect that different waxes would have differing levels of performance in this regard, but so far I've only tried Turtle Wax. I also suspect that different wheels will change the flow across the sides of the car. I'd be interested to hear if people with wheels other than the Carrera S don't have this problem.

This is a pick. Dust on lower driver and passenger doors, wheels, and rear! My car is black so it is not normally visible. Has been doing this since day 1!

 

Seems like only the German pads put out this kind of dust or am I missing something.

Had the same brake-dust mess with all my Porsches (Cayman S, 997.2 and 991).
I have tried just about everything: Various waxes (with mediocre and short-lived success), Dodge/Chrysler/Jeep "MOPAR Brake Dust Inhibitor MO-692" (with better results) and lately "ArmorAll Wheel Protectant" (repels brake dust excellently, but not cheap: 7oz. spray can is barely sufficient for two applications and costs ~ US$9. Effect lasts about 1 month).

When I wash my car and then dry it with the leaf blower I sometimes go over some area's with the Griots Speed shine or something simliar

You can use this after you wash the car to get rid of anything you missed or noticed afterwards ...

 

If it's on the paint, it's simply dirt from the road. The dust that's on the wheels is actually from the rotors. On Porsches, the pad is harder than the rotor. You must make sure you've done a proper clay, polish, and wax. This assures a clean and protected paint finish. Do not wipe the paint with a mf towel if you see this dust on the paint. It will scratch the paint. Simply wash t. If you have a good quality wax, the build up is less noticeable. If you're really wanting something that's simply to use and effective, look into nano sealant.

Hope this helps.

 

The black dust is on paint and wheels. Same dust and not road dirt. My car has one sealant coat and one of high quality carnauba wax. It comes off with a slight touch. I guess the answer is washing every few days. Surprised others have not mentioned this problem?

 

You will get the same dust with no matter what wax you use. There are some anti-repellent brake dust products but don't make that much of a difference. I use a spray bottle with a water/car wash soap mix and just wash the rims and edges of the wheel openings. An option is to go to a ceramic pad for a bit less dusting. It's not really a problem ...it's just typical.

 

I have the sport design wheels and haven't noticed the dusting problem. I have had a problem with the macguires endurance on the tires bleeding onto the paint despite how much I leave it too dry or wipe off.
