if you really love the area
clean it up the best you can and post an owner maintenance log so others will see that you have made an effort to maintain the cache. If I see the icon for needs maintenance and cannot find an owner log that it has been taken care of, I usually just avoid the area. Wait and see what happens. If the area becomes trashy again it might be time to move it, or archive it. Then the challenge begins to find another lovely spot for a hide.
At least you care about the cache you have placed. Good luck!
