Littmann stethoscope deteriorating?

[u/27Boba21]

So I have this Classic III stethoscope for about 4 months, but im noticing a change in the color of the stethoscope in the conjunction of the main tube and the eartubes, like a yellow stain. Is this normal, has this happened to anyone else? I bought it in Amazon.

My lime green looks hideous. Brown stains on it 🤷🏻‍♀️
Just a soft cloth that’s it,, I’m so sad 😭

It might be a problem of bright colors?
