At this stage I try not to let them get wet at all during the day apart from the Corsodyl Daily (once in the morning, once in the evening). The wet appearance (in my opinion similar to an icing glaze) can only be due to the residual effects of the Corsodyl as I don't and haven't been using any ointments/oils/potions since the Bactroban back at the end of May/beginning of June.
As for your second point, the strain of bacteria was originally identified as Lichen Planus as mentioned in the detailed history. It was only subsequently identified earlier this year as staph. Aureus.
