Prevent Pests in the Garden
Aluminum foil can be used to protect your garden in a few different ways. First, it helps to repel insects from eating your lush greenery if you add small strips of it to your mulch.
During the winter, you can also wrap foil around the base of small trees and plants to keep them as warm as possible. It will also deter critters such as squirrels and mice from digging up your garden.
Scrub Cast Iron Pans and Grills
Trying to get rid of caked-on grease is always a pain. However, if you scrunch up a ball of tin foil and scrub, the process should become much easier to manage.
Needless to say, do not attempt this with nonstick frying pans! It can also be used as a BBQ brush to scrape all of the burnt remnants from your grill.
