I have mould/mildew patches on the back of MDF boards on wardrobes so I applied neat white vinegar and wiped with warm water after 1 hour but the patches still remain. My husband says it won't remove the patches as seen in the pics but the vinegar will have killed the mould.
Is this enough to have killed off the spores on the MDF board and ready to paint with a sealant? Any help greatly appreciated thanks
