Do you have old computers or desktops you want to give away? If they're less than five years old, it’s best to donate the computers to a refurbisher, who can update the software and get them running in the best possible condition. Microsoft-registered refurbishers (msregrefurb.com) take both PCs and Macs, upgrade them and hand them off to charities like schools and organizations that help people around the world get their hands on updated technology. Older computers and equipment you donate can be given to charities like Goodwill and recyclers who strip them and sell the materials to raise money and keep old technology out of landfills.

With warmer spring weather here, many of us turn to power washers to blast away grime, dirt and debris from outdoor furniture, decking and the sides of houses. But using conventional pressure-washing solution can also mean spraying a non-biodegradable mixture all over the yard, into the ground and onto outdoor plants. Instead of using a store-bought solution, use one that’s effective, eco-friendly and that you can make at home. In a large bucket, mix 1 gallon water, 1/3 cup phosphate-free laundry detergent and 2/3 cup powdered eco-friendly all-purpose cleaning powder. Mix slowly to avoid clumping, and use as you normally would with your power washer.

Here’s how to disinfect and deodorize a kitchen towel and clean your grimy microwave all at the same time. Rinse your kitchen towel in the sink, and ring out the excess moisture. Place it inside your microwave and zap it on high for about 2 minutes. The microwave will disinfect the towel by heating it up, while the moisture from the towel releases steam, loosening up grime and making cleanup a breeze. Just wait a minute before wiping away the inside of the microwave with a damp sponge -- or use the towel inside and then launder as usual.
