one thing that i have noticed that no one has put on here, i know its a bit like common sense but is not to pull the shedded skin off, but brush it slightly with a soft brush, if its still stuck to the bd, DONT PULL IT, as said before its a bit like us when we see the sun (?) ie go red and then peel, if you pull a stuck bit, it hurts like hell and bleeds, if this does happen, put a small amount of iodine onto it and it will heal up ok
