I heard that raw egg yolk can remove coffe stains but why is it so and what 
is the component of coffee that causes the stain in the first place? Then 
why is it that vinegar is reputated to be a good tea stain remover?? What 
is it in tea that causes the stain and how does this react with vinegar to 
remove the stain??
