To get dried-on bits of chewing gum off of shoe sole.
I tried the following but they did not work very well, if at all (using an old toothbrush to scrub them on the gummy parts): rubbing alcohol, blue Windex-type window cleaner, 409 cleaner, peanut butter.
WD-40 was suggested on a few pages, but I didn't have that.
Then I tried a few drops of mineral oil and some baking soda, scrubbed with the toothbrush. Followed by foaming soap to clean it off. That worked fairly well.
If there are still any thick areas of gum that I didn't previously scrape off, a small screwdriver works well, before the above steps.
