Professional-Grade Stain Removal Kit or Service for "Forever Stains" on Clothing

There's a clear demand for highly effective stain removal solutions, particularly for "forever stains" on important garments like work clothes. While many general stain removers exist, users often find them insufficient for tough or old stains. A product opportunity lies in developing a specialized, perhaps multi-step, stain removal kit or a professional service that targets deeply set or specific types of stubborn stains (e.g., oil, ink, dyes) on various fabrics. The kit could include different formulas, applicators, and instructions for various stain types, offering a more powerful solution than general household products. The service would cater to those who value their garments and prefer expert treatment.
