This is an excellent stain remover and uses considerably less plastic packaging than what’s usually available. Just rub the bar on the stain, let it sit a bit then wash. If you’re cleaning fabric rub the fabric on both sides of the stain with the bar. I have been very satisfied with this product.
Sadly the bar does arrive with a thin plastic tray inside the cardboard box. This seems unnecessary.
Astonish bars are available on Amazon for $7.74. They last a long time. They have other products but I can’t recommend them because they have plastic packaging.
