One way to do it is, if you click on your profile and hover over your header on the right, you should see an "edit" which you would click and then from there a small window should pop up to "edit profile". Scroll all the way down until you see "Wiki's you've contributed to:" and at the very bottom left near the grey area there should be a "recycle" icon. If you click that, it will list all the Wiki's you've made edits to and you should see it. Keep clicking on the trash icon next to the Wiki's until you find the Wiki you were looking for.

Hope that helps :)
