An automatic car wash is the most water- and energy-efficient way to wash a car, and it's especially useful in the harsh winter months. When roads are treated with rock salt to deice them, the mixture of melting snow and ice with the salt can cause rust on the undercarriage of your car. After a harsh storm, visit an automatic car wash and opt for the undercarriage cleaning along with a hot wax seal. This will wash away the salty mixture and create a barrier that will protect your car from further winter damage.

Many of us choose to buy our holiday gifts online and have them delivered in lieu of going to the mall. When buying gifts online, opt for ground shipping instead of express shipping; it's a cheaper and more fuel-efficient way of delivering gifts. If you want to double the efficiency of your packages, have them sent to your place of work instead of to your home. Since delivery companies like UPS and FedEx already make stops at corporate offices, they won't have to make additional stops to infrequently visited homes. This helps cut down on fuel usage.

Denim jeans are one of the most-owned items by both men and women in the United States, so it makes sense to take care of them properly so they look good for longer. First, always wash jeans in cold water and turn them inside out. This will help retain their shape and won't hurt the finish of the jeans. Skip the dryer and let them dry out on a clothesline. You can even just drape them over a hanger and hang it on a door if a clothing line is not an option. Finally, when it's time to get new jeans, donate your old ones. The most re-sold item at Goodwill is jeans, so it will gladly take them from you to raise money for its charitable works.
