Whats the best way to get rid of the wax that creeps out of the cracks after you wax your vehicle?

Horse hair toothbrush. Buy at auto cleaning supply

If you get wax on rubber/plastic parts, I've had good luck getting rid of the residue with a little ATF on a cloth. Then you can wash it away and put some other type of protectant like Armor All on it.

ATF.... Auto transmission fluid?????
