How to remove coffee stains from white wool jackets

1. Sprinkle coffee on the clothes, take it off immediately and rub it with hot water to wash it clean. For old coffee stains, you can use a mixed solution of glycerin and egg yolk to apply the stain, and then wash them with clean water after they are dry. First apply glycerin to the coffee stain, then sprinkle some boric acid powder, then soak it in boiling water and wash it to remove it. Use dilute ammonia water, borax and warm boiled water to wipe the coffee stains, which can also be removed.

2. Breathe excess sponge dyed water. Apply water-based detergent and a few drops of white vinegar. Wipe with water-based detergent cover. Let it stand as long as any stain is removed. Change the pad as it picks up the stain. Keep the stains and absorbent pads moist with water-based stain removers and vinegar. Repeat with clean water until there are no more stains.
