Getting Black Spots Off Rims

[Blackdevil77]

Hey all. I'm not new to Adams stuff, but I haven't really posted here that much. I just got my car washed for the first time in a while. The temperatures over here have been well below freezing for a very VERY long time, and today we finally hit 60 degrees  

 

After I cleaned my car, and the wheels, I noticed black spots on the wheels that just won't come off. The bulk of the grime and break dust came off, but there are spots on the wheels that are much more stubborn. I can feel them with my finger nail, but they won't budge. What are these black spots and how can I get them off? I used detail spray, and a rim cleaner and neither worked. I haven't tried Adams wheel cleaner yet, but decided to post it here to get some insight from those much more knowledgable and experience than me before I buy anything. 

 

Thanks! And here are some pics of what I'm talking about.

I would clean them first with Adam's DWC then if there are any  black specs left I would clay the wheels.......when cleaned I would protect them with QS.

If it's baked on iron particles, DWC will take it off, but if it's tar, APC may help but you will either need to clay them or buy a tar remover.

Looks a bit like tar, I would try all purpose cleaner first then tar remover if necessary.

Thanks guys. I have some all purpose cleaner and clay bar. I'll give that a shot tomorrow. I'll order the deep wheel cleaner also. I'll report back with the results. Thanks again!
