History of the Invention

[0004] Removing fabric stains can be challenging. Washing stained fabric with a detergent can produce a satisfactory result if the stains are light and not greasy. However, if the stains are heavy, washing with detergent often does not remove the stains because the detergent ingredients are diluted in the wash and not concentrated in the stain.

[0005] To successfully remove heavy stains, it is known in the art to apply a separate stain treatment, for example by spraying or squirting the stain treatment product directly onto the stain or a wipe impregnated with a stain treatment product. stain to rub a stain.
