• • Coffee stains on cotton  : the simplest method is with boiling water and a few drops of hydrogen peroxide, but this only when the stain is fresh. If it is dry, rub it first with glycerin and then with ammonia.

• Coffee stains on silk  : the fabric is very delicate so you have to be very delicate. The most effective method is that of apple cider vinegar, already explained above, but with the difference of leaving the garment to soak overnight in a container with water and two cups of apple cider vinegar. Just the next day go and rinse with cold water.

So be careful with coffee cups because the stains it leaves are very stubborn. However, coffee not only stains but there are also numerous remedies with the grounds. For example, they can be used in some household tasks but they can also be an excellent fertilizer for plants.
