I've been putting off cleaning the rear wheel wells and underside for a while now. This morning I decided it's probably time to get this over and done with.
This is the stuff I used, it's fantastic with minimal agitation required to get excellent results. As I mentioned before, this stuff is pretty corrosive so don't let it dwell too long
This is what I was faced with when I took the rear inner linings out
Notice that you can't see the alu struts and arms. Now see what it looks like with minimal effort. I'd guess I spent 15mins max on a side
Inner lining back again and a little AF Dressle just to make it pretty
I also tackled the underside of the car and gave it a real good clean. Again, no agitation was needed, just a 3 minute dwell and the HP cleaner.
Finally, I used a sealer on the mags to make them easier to clean in future.
