HG mold spray and foam spray are very powerful at removing mildew (they're labelled as bathroom but ignore that) the foam is more powerful and less air bourne, they'll leave a fine residue to wipe off. [Mildew will happily live under poorly adhered lining paper slowly removing it]. You can get additives to add to any paint but the standard is zinsser perma-white (matt or satin) and that can be tinted.
