Do white cabinets turn yellow over time?

When white cabinets turn yellow, it is mostly a problem with the board material and workmanship, not the color white itself. Cheap white boards will yellow over time from light exposure and oxidation, especially near windows. Choosing PET door panels or double-faced boards greatly improves yellowing resistance, and using PUR edge banding or laser edge banding can also reduce moisture absorption and discoloration at the edges.
