When I bought my 2016 in matte white, I researched matte safe cleaners before the first wash. There are plenty available, but most had to be ordered online. The Meguire's website said a few of their products are matte safe, including their Ultimate Quik Detailer. I bought some at Wal Mart, and have had good results. It doesn't add any gloss to the finish that I've noticed. The bike still looks great except for a few chips that are very difficult to repair on matte paint. One area that has picked up a slight glossy appearance is the saddlebag lids, which is due to being pressed closed hundreds of times.
