Drive on them less and use armorall.
the best thing i have found to protect rudder is armorall tire foam.
Armorall is pretty good. There is a picture of a Viking in the front of their products.
Make a paste of Tide detergent and hot water. Scrub it into the concrete and let dry. Rinse off with a hose.This answer was emailed to me from ArmorAll customer service.
No. ArmorAll itself says not to use it on leather. Repeated use on leather will cause cracking and deterioration.
Tilex. Then rinse, but don't use ArmorAll afterwards. Get Meguiars rubber and vinyl #57 (RV and Marine)
wash it real good with soapy water rinse let dry and use a lot of baby oil, no armorall
You can limit the amount of direct sunlight the canopy recives daily.You could also look into protectant products such as armorall,depending on the type of material the canopy is made of.
the best way I have found is scrub them with a brush and then apply armorall ( the kind that turns them back black even if ther not is best)so they shine and look unoxidized If they have lost their color, you could just do what I did and paint them with Krylon Fusion spray paint (made for plastic.) Just make sure you tape everything off.
I am assuming that you are referring to personal rather than commercial products. The highest rated personal detailing products are armorall. They clean the vehicle the best without leaving any unsightly residue or streaking.
