Targeted Collar Ring & Stain Pre-Treatment Spray
The user identified a 'ring on the collar' stain that appeared or worsened after washing, indicating a difficult-to-remove or set-in stain. A specialized pre-treatment spray specifically formulated for protein, oil, and sweat stains common on collars and cuffs could offer a more effective solution than general pre-wash sprays. This product would leverage advanced stain-fighting enzymes or surfactants to penetrate and break down these stubborn stains before the main wash cycle, ensuring better results for a common laundry problem.
