Watch out with alcohol, it will smear the ink on some unlaminated covers. It can also sometimes strip off the lamination. I notice some places sell a 50% solution that should be mild enough for most uses. I throw out the plain inner sleeves if the mildew smell is strong, and wipe the covers down carefully. I would take off the cellphone and throw it away if you don't need it. If you can leave the covers outside in partial sunlight on a mild day it will do a lot to reduce the smell - not glaring, hot sunlight which can warp the covers, but a partial shade.
