you can consider rafacing it.

I usually use Mr. Clean on kitchen cabinets. If that doesn’t work, try a pretty strong solution of warm water and baking soda (use gloves to protect your hands). Good luck!

I use bleach on mine but you MUST keep your windows open when applying it. Then wash off with warm water and if this doesn’t work use KABOOM on them. The bleach smell to high heaven but it’s well worth it for the results. Unless they are really bad the bleach should do an excellent job.
