Orange Spice Thai spots I could on a beige wool sweater nearly without residues to remove it. A light sheen of orange is jedoh stayed back even after repeated treatment.
On a gray sweater with brown spots on the back of the medium has changed nothing.
I think the stain Roller good for moderate stains. With Ariel Stain Pen but I have done something better experiences.
For the price there are many other good alternatives. I recommend at the grocery store only once to test a cheaper product and to buy these expensive failure only stain stick. The stain pen is not better, it acts only with another variety of stains as chemical sprays
