So we're thinking of taking my daughter to the zoo in a couple hours, and I brought her big stroller in the house to clean it up (it's been on our porch for the past couple months because we have been using her umbrella stroller)

Is this mold/mildew and anyway you know of I can get rid of it in the next couple hours without a washing machine? I really want to use this stroller for the zoo and not her umbrella stroller. It's just on this part of the canopy and just in that little area.
