Homeowners unable to remove stubborn black mold and stains from bathtub surfaces

Homeowners struggle with persistent black marks, mold, and mildew on bathtub bottoms that resist standard cleaning methods and commercial cleaners. Current solutions like bleach, vinegar, and store-bought scrubs either don't work effectively, require dangerous chemical handling, or damage the tub surface. This creates frustration, health concerns about mold exposure, and the costly alternative of professional cleaning or tub replacement.
