I just removed the caulking around the bottom of my shower stall (where the floor tile meets the wall tile). The caulking showed little or no evidence of mildew, however the underlying grout has mildew. What do I do, merely disinfect the grout and allow to dry and then re-caulk or do I have a bigger problem here? I don't want to make a costly mistake.
Thank you, in advance, to anyone out there who could give me some helpful advice.
