How can I remove mildew prior to painting an interior surface?
A. Remove all mildew by scrubbing with a solution of household bleach detergent and warm water (1Quart bleach, 1 cup T.S.P. + 1gallon water). Be sure to wear rubber gloves and eye protection. After you’ve scrubbed away the mildew, rinse thoroughly with clean water. Mildew that is not removed or only partially removed, will continue too grow through the topcoat of the new paint.
