Hey Lawrence welcome to the forum. We have discussed mildew and how to remove it at length on this forum over the years. Do a search at the top of the page. Type in mildew and all kinds of threads will pop up regarding this subject and how forum members have dealt with it and what products or solutions they have used. Personally I have been successful using a diluted bleach/ water solution in a spray bottle and just applied it on the mildew, watch it disappear, rinse, and let dry.
