"Wipe New Trim Restorer" from Rust-Oleum will keep all the black plastic pieces looking new forever. Apply to a clean car about twice a year. It may be at Lowe's, etc., but I have ordered it on Amazon for my 2020 Outback Touring XT. It used to come in a small bottle with a couple of cloth applicators. It now comes in a presoaked cloth in a foil pouch, which is not as easy to use in my opinion. Use the gloves it comes with, you don't want this stuff on your hands. If you buy the presoaked cloth version, squeeze the excess out into the pouch before applying. Then, freshen the cloth with the excess liquid as you go around the car. If you use the presoaked cloth without squeezing out the excess liquid, it will go on too thick and may leave "runs" in the finish.
