I saw something on Pinterest recently for a homemade 'Goo Gone' which is supposed to work well to remove the sticky residue from labels and price tags. But when I had a label to remove recently, I couldn't remember what the recipe was, and realized I hadn't pinned it. So, I reached under my sink and grabbed my handy can of Bar Keepers Friend®. Guess what? It worked wonderfully!
There was no scrubbing involved or trying to figure out if cold water would work better than hot. I just sprinkled some on my sponge, added a little water, and wiped the gunk off. It was awesome!
Of course, I've only tried this twice, once on plastic and once on glass, but I really need to remember this in the future. That sticky, gunky residue is always such a pain.
Have you found anything that works for you? If you have some of this stuff, give it a try.
