I've used the cleaner Nothing special if your out in the desert I'm sure their is fading on the plastic sections mirrors etc possibly top. I just use armor all even on the top I always get asked if its a new top. The question is I don't live near a desert and don't know if you would get sand stuck to it,if you have a black top you will attract more sun. Give it a shot can't hurt. It will fade regardless. Auto parts sells trim restore I've never uses it I heard it works good if you just want to clean it get a magic sponge car soap and water.
