210
I use 210, also. It waxes, but also renews the oil in the vinyl. It's in an aerosol spray can and sells at Boater's World. I use it for waxing (Use water ONLY with a VERY soft cloth to remove the dirt, first). Then I use the 210 in and out.If your clouding doesn't go away or is mottled and brown, then you may have a fungus/bacteria that permeates the vinyl. That's when replacement is mecessary.
