I try to be very careful in cleaning the clear plastic lens over the instrument cluster, but I still get small scratch and swirl marks that show up whenever the sun is able to shine right on it. It is distracting and even makes the cluster hard to read when the sun really shines on it. I have used microfiber, soft cloth diapers, lens tissues, etc, on my two 4Runners, but have still gotten the small scratches. My '05 isn't too bad yet, but I don't want it to get any worse as happened with my '04. I try to blow dust off before wiping the lens, but thus far all my efforts have failed to prevent these scratches from appearing. Does anyone know if any cleaning method will prevent more scratches and if anything is able to remove or polish out the marks? What is the plastic? Lexan? Lucite?
