Carpet Stain Color Corrector/Remover for Cleaning Product Residue

The user encountered a specific problem: a common stain remover (Shout) left a purple hue on their carpet. This highlights a gap in cleaning products – not just removing the initial stain, but also correcting unintended discoloration caused by other cleaners. There's a clear demand for a solution to this 'secondary stain' problem, especially when move-out inspections are strict. A specialized cleaning product designed to neutralize or remove color residue left by other carpet cleaners, or a 'color-safe' carpet cleaner explicitly formulated to prevent such discoloration, would address a frustrating and potentially costly issue for renters and homeowners alike.
