Over the last 10 years, 99% of our lighting has come from thrift stores, garage sales, auctions and the like. They've all been vintage finds and as much as we love them, sometimes getting a light bulb in (or out of) an old socket is done only after saying a small prayer that the bulb won't stick and break in our hand — but not any more!
To remedy old and sticking sockets simply use a small bit of lip balm on the inside of the threads and the light bulb won't have any problem screwing in! You can also apply it to the bulb instead of the sockets — it's a great preventative measure, especially with new lamps. Just be weary of the very bottom of the bulb or socket being coated. If you're worried things will get messy, just use a cotton swab to apply.
Your new and old lamps and light bulbs will thank you and hopefully you'll never need to remove a broken bulb, even if the technique is safe!
Editor's Note: It takes hardly any product to accomplish this. The lip balm shouldn't be slathered on thick in the slightest. It only requires the smallest amount of product to make this trick work and to keep everyone safe along the way.
