I'm certainly no expert, seeing as I have fairly recently gotten into this hobby myself, but my guess is that most experts will tell you that if your intent is to maintain the highest value, unless the coin is dirty from something that will cause it to be damaged if left on (like PVC), then you are better off leaving it uncleaned.
From what I can tell, this coin appears to have normal wear, so I wouldn't touch it.
