The milk ran out and you did not have time to consume it. But that does not mean you throw it away. There are alternative ways to use it and you may not believe in its incredible uses.
See below:
Clean the silverware
Use sour milk or expired milk by adding a little vinegar and rub the silverware well with a cloth. Clean with a damp cloth and wipe with a soft cloth. You have never seen such shine.
Remove ink stain
Ink is a difficult stain on fabric. Soak it overnight in milk and rinse well the next day. The milk will dissolve the ink and the clothes will be easier to clean during washing.
Clean the furniture
With the mixture you use for silverware and following the same procedure, polish the wooden surfaces, as the milk will moisturize the wood in the best way.
