How do you clean the yellowing on a vinyl fence?

Most modern vinyl fence products are created with a co-extrusion process that adds a layer of UV protection (also called titanium dioxide or Ti02) to the exterior of the PVC fence. This UV layer will typically prevent the yellow coloring that can occur from extended exposure to the sun.

Yellowing can occur, however, in highly humid conditions from mildew and mold. If yellowing does occur, there are ways of removing it to bring your vinyl fence back to life. Water and either vinegar, bleach, ammonia, or other citrus-based cleaners will usually do the trick.
