Thanks to my love of up-cycling things around our house to make new projects from, one of the things that I've become an old pro at how is removing labels and gooey stuff from glass bottles or any other glass container.
The first tip is DON'T get the label wet!!! Peel as much of it off as you can, then take a straight razor and scrap off the rest of it that you're able to.
While doing peeling and scrapping off the label, boil some water. Once the water is boiling, carefully and slowing using a funnel, pour the water via the funnel into the container you want the label off of. Just a quick heads up, pour the water VERY slowly into the funnel, the boiling water will pop up and hit you if you're not careful!!!
Let it sit for 10-15 minutes. Using potholders, carefully pour the water out of the bottles. Still holding the bottles with the potholder, pour some fingernail polish remover onto a paper towel. Wipe the bottle down until all the sticky goo is gone. Sometimes there might be a little sticky stuff left on the bottle, take the straight razor, scrap as much off again as you can, then wipe again with the nail polish remover. You may have to do this a few times...
The end result is a nice clean bottle or any other glass container with no more label.
