Hello, eveyone. I brought this product to remove the armpit stain of my shirt . The stain of a shirt was very strong stain . Even after so much of wash the stain was still there . Then I thought to try this remover . As I want to wash the shirt with this remover . I directly applied remover on the stain area . After the wash the stain was the same as it was before the wash . It was of no use to use the remover . It is not effective . It use is easy but not efeective
