While cleaning I notices that my Baltimore body has a different color tone (yellowish warm) compare to her face (btw I shining direct light to see the difference better). I'm not sure am I facing a staining issue here... FYI: I don't smoke.

Can someone compare their Baltimore if facing the same issue as I have? I had her about a year already.

Also is their a safe solution to get rid of the yellowing?

For future practice, what measures should I do to prevent this yellowing again. Previously, when I had her I use bare hand then I started using latex glow to handle all figures.(not sure could this be the cause?)
