vinegar.....having lived in the SOUTH for many years and even on the Med in Italy everyone knows you use vinegar to kill mold spores...it even removes the stains from cloth!
and 200watts...really....I think 25 or even 40 would be more than enough...any more than that and the heat could damage the fabric lining and destroy the glue that is holding it!
but I would skip it and spray with water/vinegar, set in sun and then add the charcoal odor eaters!
