You can polish your shoes with a banana. It is a great way to reduce waste.
How? First, you consume the banana. Second, rub the inside of the banana peel against your shoes. Then, acquire a soft cloth and buff your shoes. The natural oils and potassium in the banana help to polish and preserve your shoes. Great activity for parents to green-educate your children. Don't worry about leaving weird smells or attracting insects as it has been experimented and abided by many eco-friendly people.
The same technique can be use for silverware.
