But not strong enough.
Bloody h*ll man. This stuff seems to be permanantly stuck on!
The only thing the Brakleen properly cleaned was the back of the muffler (which is now shiny again). But i think it was only dirt on it.
I give up. The only thing that could remove this stuff by the looks of it is some sort of metal polishing equipment (i was out there for about an hour or more).
Waste of $14.00.
