Alcahol always seemed to cut brake fluid. Its not a petroleum product so the usual solvents wont work.also petroleum based products will dissolve your black top unless it has been treated with Jenite which I doubt it has as this costs as much as the blacktop.

brake fluid is oil and alcohol mix in various proportions. used to be castor oil and propanol. I think, they switched to glycol now. Oils are not water soluble, they can be dispersed in water, emulsified, but that does not help cleaning.
Blacktop as in asphalt? Concrete cleaner + pressure washer. worst come to worst, buy some tar, melt it, and paint it over. They have asphalt "paint" at HomeDepot. Basically, it's a tar, main asphalt component. Will look too new for a week or so, then rains and dust will bland it in.
