My Pretty Female Friend That Confessesed To Me Smells HORRIBLE

Hey Reddit, I'm in the same uni class with a girl. Me and her have been friends for 2 years throughout uni, and yesterday she confessed to me that she has a crush on me. I'm on a catch 22 situation right now and I hope I don't sound mean. The reason I "friendzone" her, is because she smells like wet tissue after being used to wipe poop. So there's like this really distinct smell from wet tissues, yeah idk how to describe it; if you know you know. I do think she's a pretty girl, and she's also a smart individual, but I really prioritze hygiene when it comes to being in a relationship. Could anyone give me advice? Should I just communicate it with her? I don't want to sound mean towards her.

TLDR: Female friend has a crush on me, but I'm hesitating to give her an answer because she smells like wet tissues mixed with poop.
