I've been using spray nine as a cleaner and then following up with 303 for a conditioner/protectant.
The spray nine seems to do the job reasonably good and have been using it for years.
303 seems to work good at what its intended for, but it is a magnet for dirt and dust, and feels abit 'slimy' after application.
Also do any of you use mildew remover/preventer.
Just wondering what your favorite products are for vinyl care.
