The "white stuff" comes off w/ a detailing brush, don't use a tooth brush, even an old one because they're a little abrasive

As far as the color cream stuff goes all I can say is...GIMICK :p If you wanna see what the Mequiars 3 step is all about come over to the SE MI forum and click onto the pics under "Detailing business is in full swing" and tell me about Mequiars :p
