Magical vinegar

Vinegar is said to have magical stain-removing properties. I'll test 4 common types of stains, and their methods of removal using vinegar.

1. Removing chocolate milk (protein) stains - If you can get to the stain before it sets, treat it by pouring full-strength white vinegar on the spot. Let it soak in for 5-10 minutes, then blot well with a cloth or towel. Repeat if necessary, then wash immediately. If the stain has set (esp for more than 24hrs), it is almost impossible to remove it. <-- I could try debunking that!

2. Removing tea (tannin) stains - Flush the area with vinegar to remove the stain. Rinse and repeat as needed. Then wash as usual.

3. Removing grease (oil-based) stains - Soak the stain in undiluted white vinegar. Then wash as usual.

4. Removing ink (dye) stains - Apply vinegar to the stain. Then rub with a paste made of vinegar and baking soda. Dry then wash.
