I've used an ordinary cotton towel for years on my convertibles; as you put the top down and the window begins to fold, insert the folded towel in the "V" formed by the folding plastic so the window won't rub against itself when it's fully down. If you have scratches in the window, both Meguiar's and Mother's have 2-stage plastic cleaning and polishing products made specifically for plastic convertible top windows.
