Rennac couldn't help but chuckle seeing the Litharian trying to find a clean spot for his weapon, shaking his head at the request. 

"My armor's gear only works when it's attached. Lets me clean them easily while keeping marks from trying to take pieces off and fire them at me. Just point to a spot you like and I'll cover the spot. Though I am surprised a bit of filth is enough to wig you out. True, don't exactly enjoy it myself, though it apparently doesn't annoy me as it does you."
