This Kabi Killer value pack includes one 1000 g trigger bottle and two 1000 g refills for repeated bathroom deep cleaning. It is a strong mold remover made for damp areas where black mold builds up, such as tile joints, around tubs, and other hard bathroom surfaces. The formula is known for penetrating clinging mold and the pack is designed for households that use it regularly rather than as an occasional cleaner. It is best for shoppers who want a larger stock of the standard spray plus refills in one practical set.
