Answer:
White vinegar removes rust.
Hydrogen peroxide removes bloodstains.
Hairspray removes inkstains.
Step-by-step explanation:
You can use a number of household items to remove these types of stains, but I have listed the ones I have used personally to greatest success. With bloodstains, water usually works if you can get there fast enough before it dries. Milk apparently also works for inkstains, but I've never tried!
