We have been using Should Stain Remover to remove spots on clothes for couple years. The stain remover is safe and simple to use, just spray it on the spots before wash. It really works well on removing all the stains on our clothes so far. According to the reviews from Amazon and Walmart, majority users feel the same as us: Shout Stain Remover does great job on removing spots and even the tough stains.
Costco currently cuts $3 off on Shout Stain Remover, dropping the price to $6.89. It comes with a 22 oz spray and a bottle of 170 oz. refill.
