If you have some old, faded electronics or other plastic gadgets in your house, you can make them look great again with just a dab of Vaseline.
Flickr user linux-works discovered, after buying some old audio equipment on eBay, that a simple wash with soap and water didn't do much to help the old, faded, plastic knobs. However, a bit of antibiotic ointment (which uses a petroleum base) shined them right up -- see the picture above. The top knobs have been restored, while the bottom knobs were merely washed with soap and water. Just rub it on, leave it for a minute, then wipe it off. Hit the link to read more.
