I use Simple Green to clean my sedan tires. I race mostly on concrete and asphalt and get good results.
I will use TQ Blue for the practice runs and if I like what the car feels like, then I will apply the TQ before the first heat race then use the Simple green for the rest of the races.
If the track feels greasey then I will just use the Simple Green before every run.
The TQ works best if applied maybe 15min or so before the race. Let it set on the tires for a few minutes, then wipe off.
The Simple Green dries faster so it can be used right before the race.
Works for me.
