Bed Chair care

[fullcreel]

My bed chair, which lives in the shed/work shop has begun to get some mould, a type which I think is one of the mildew family, can anyine recemend a treatment, which will hopefully not stink, like Jeyes or Damage the material?

a capful or two of bleach to a gallon of water.
then lemon and salt in a gallon of water .
it may discolor it a bit
then let it dry off well
