Use a mould and mildew spray.
Spray and wipe excess with m&m or a moderate bleach solution. Then I’d recommend decanting into a tub and painting it on thick with a paint brush.
After painting soliton on. Get some air flow - open as many windows as you can on dry day (doesn’t need to be warm). Might be worth doing on a day you can be out all day or away for weekend if it’s cold.
Ultimately get the fan fixed - shouldn’t cost too much to replace but the issue will be finding a sparky. |
