I purchased my TL recently and I want to clean it up, since it's so dusty (really shows up on black). I'm getting some of the Zaino's line of products (Z-2, 6, 7, etc). But I was wondering...

For my weekly washings of the car, could I just use some other brand of shampoo, or do is it better that I stick with their shampoo?

Thanks in advance.

 

For regular weekly washing, you can use off the shelf shampoos. I've been using Meguiar's Gold Class and NXT without any probs.
