These are all I currently have experience with:

I use these on my seat of course, but they are great on any smooth interior surface (not painted or shiny plastic). The leather racing seats I had in my Camaro used to suck these things up, and man did it make them look great. These are a good product, and make cleanup easy.
They also have these that I am going to try:

Those are just for all interior surfaces. The quicker and nicer it makes it, the better.
