- Fill a basin with 3/4 of a cup of bleach and a gallon of water. Mix thoroughly using a paint mixing stick
- Fill another bucket with warm, clean water.
- Put on rubber gloves, and dip a sponge into the bleach solution taking care not to get the solution on your skin or near your eyes or hair.
- Scrub the wooden rafters with the sponge until the mildew stains are gone.
- Immediately rinse the rafters with the warm water in the other bucket, taking special care to remove all of the bleach solution. Any remaining bleach can be a breeding ground for mold spores so be very careful to make sure that the bleach has been completely rinsed.
- Dry the rafters thoroughly with a soft cloth, getting all moisture off of them to avoid causing any damage to rafters.
- Fill a spray bottle with vinegar and spray liberally over the surface of the rafters. There is no need to dry the vinegar, it will evaporate on its own and act as a deodorant and a disinfectant, inhibiting the future growth of mold and mildew.
