Unscented items.

You know, in my mind, something that is unscented should have no smell to it at all.  But many times I find myself attacked by a pungent aroma of stagnant water.  Take for example my hand sanitizer.  I bought it because it was "unscented".  Sadly, the second you open the cap, my nose is overrun with with a repulsive, vomitrotious odor.  Totally unusable.  Also annoying?  Trying to think of all the different ways to say "scent" without using a thesaurus.
