I don't know how many times, it will be days after I've recently detailed one of my cars and I'll find some wax/polish to pick out of cracks on the car. How are you removing all the wax and polish from cracks on the car? Brush or some sort of plastic wedge?

Where on the car specifically is giving you trouble? Theres a few different ways you can go and methods you can use.

Tooth picks work great.

:goodpost::goodpost: and just be careful how you apply it.

Thats why I apply it really careful around the cracks so it won't get in them in the first place.
