Cabriolet owners: what's the best cleaning product for your car's exterior fabric roof? What's the best protectant for UV damage and water/stain repelling? I live and drive in Hawai'i, where UV intensity is usually very high. (BTW, mine is a 2019 E450 Cabriolet with black top.) Mahalo (thanks!) for any recommendations.
