Moldy Pulling Rope?

I recently started with a new company that uses a trash can to store their rope. As we went to use the rope at the addition to the hospital we noticed that the rope was covered with mold. Is anyone aware of a chemical that would clean the rope without damaging it ?
Is this mold dangerous? I am reluctant to use the mold covered rope anymore, but the other employee’s say this is normal. the company that I used to work with always stored the rope on a spool where it could dry out after every pull. I don’t want to make waves with this economy, This isn’t safe.
Please help
Thanks
