And just to add a very cheap and readily available alternative......Bikers, when cleaning plastic visors often use toothpaste....start with lots of water in the mix just to be sure but there is no way it should scratch. I once caught my visor on a hotel door frame and there was even paint transferred onto it, all cleaned off with a few minutes with toothpaste and tissue paper (loo roll).
