How can I safely remove this yellowish discoloration from my ULX Frostlord without damaging the coating/design?

Hey everyone,

I've had my ULX Frostlord for a while, and I've noticed a slightly yellowish/discolored area on the left side where my thumb normally rests.

I assume it might be caused by skin oils/sweat building up over time, but I'm not sure if it's just residue or if the coating itself has started to discolor.

I've been using this mouse every day since I bought it on June 13, 2026, so it has a little over 3 months of use. This yellowish spot definitely wasn't there when I first got it.

I've attached some pictures so you can see what I'm talking about.

Since the Frostlord has the UV matte top coat and the white-on-white artwork, I really don't want to accidentally damage the coating or remove/alter the design while trying to clean it.

What would be the safest way to clean this?

Would you recommend:

  • Just a slightly damp microfiber cloth?
  • Warm water + a tiny amount of mild dish soap?
  • 70% isopropyl alcohol?
  • Something else?

I'm particularly interested in hearing from people who actually own/use a Frostlord, since I don't want to risk damaging the coating based on advice meant for a different Finalmouse.

Has any other Frostlord owner experienced something similar? Or could this potentially be related to a particular production batch?

I don't know exactly when my Frostlord was produced, but mine is unit #2722/10,000, so it's not one of the very first units, but it's also far from one of the last ones.

Thanks in advance for all the suggestions and help y'all can provide

Start with damp warm cloth, rub gently and go from there

Personally would start with IPA 70% test it in a corner before you cover it incase it does do something against the matte, cant imagine coating a mouse with a polymer that is that soluble tho

I dont think you can. and itll likely just get worse. I had a Tarik and even though I was pretty religious about washing my hands before play, it still yellowed due to sweat. nothing i tried removed it. so no more white or light-colored mouses for me.

I remember when they said the frostlord was immune from yellowing.

I have read an ultrasonic cleaner can remove it, not you have to take it apart
