I'm going to take the Leap and wash my car myself .. it's been years lol. All they have is the house brand stuff - ( says safe did all surfaces) and meguairs deep crystal , and gold class . Those seem to be the only three that don't have wax in them

Order Koch Chemie GSF or Dr. Beasleys for matte paint. Good stuff.

Some of those other soaps you mentioned may not have wax but still may add shine...who knows.

Dr. Beasleys for the win!

It's rare to find matte specific soaps at a local parts store. Online will be your best bet.

Like posted above, Dr Beasley's is the best you'll find. All of their matte products are incredible. And from what I remember, they were one of the first companies to jump into the matte game over a decade ago.
