This may be old hat to a lot of people, but I did not know this works on stains such as ink in breast shirt pocket, blue berries on a aqua marine polo, or red wine on a white table cloth.
Gets some common dish soap, baking soda, and hydrogen peroxide and rub it in. I was amazed with a little fingernail scratching, the stain came out but left the color intact!
Who knew? probably everyone but me lol
