No, the Maiden powers can hurt Grimm. They can hurt any living or non-living creature. It's just that Maidens are supposed to be a secret, so they cannot openly use their powers or they can use it in emergency situations. It's just people think she's the Winter Maiden because she "froze" the Grimm dragon. But there's no ice involved.
