How do you remove mold from a polyester stroller cover?

Pee on it every minuit contuinuosly until you reach the 5th minuit.

Once you have done this place it place on the floor ( still wet ) and jump on it 9 times on the 'mold stain'

once you have done this wash it would under the tap until water runs cleear then dry with a hair dryer until damp.

once you have completed all these stages you can then place it in the washing machiene for a normal wash and the mold stain will be gone.
