I spray some on a paper towel and then run my tires through it. Then on a clean paper towel I will drag the car across it at a 45 deg angel rolling the tires. You will see all the crap come off. Your car will handle like crap for a few seconds and then watch the magic happen!! Instant traction just add WD-40.

I used to make my own tire sauce back in the day.

WD-40
MEK (Methol Ethol keton)
VHT ( Very high traction)

An extremely flammable combination but very very grippy.
