Should I replace my Mac's keyboard and trackpad after spilling coffee?

So, I had a little accident with my Mac—spilled coffee on it. 😩 I rushed it to a repair shop to get it cleaned ASAP. They told me the trackpad and keyboard were damaged.

But… after two days, everything magically started working fine again. Now, it's been about two weeks, and it's still running without issues.

Should I take it to an authorized Apple repair center to replace the keyboard and trackpad just in case? Or should I just let it be? 🤔 Any advice?
