PVC fence panels can turn yellow over time because of the material quality and the amount of UV inhibitor added during manufacturing. Cheaper panels often lack enough protection, so sunlight causes them to fade or yellow. Higher‑quality panels contain more UV stabilizers, which help them retain their color longer.
To address the issue, a power wash with a vniyl cleaner can restore brightness if the problem is only surface dirt or mildew. If the panels have genuine UV damage, the only real solution is to replace them with higher‑quality panels.
