Just use Zout Oxy Foam. It comes in a purple spray bottle and it may have saved my life.
My friend stepped in some gum on the ground without realizing it, then got in the car, pressing the old gum into the floor mat. If it wasn’t my dad’s car, I probably would have just taken the lazy route and left it until such time as it caused a problem for me, but it was my dad’s car, and I therefore couldn’t just ignore it.
Going in, I had no idea how to remove old gum from carpet, so I did a quick Bing search. The most popular answer was “put ice in a plastic bag and set that on top of it, then scrape it up with a spatula or dull knife,” so I tried that.
Pffft. Yeah right.
That got me nowhere, so I raided the laundry closet and grabbed the bottle of Zout Oxy Foam, which I guess is actually intended to soak a stain before you put it in the laundry rather than use as a carpet cleaner, but I’ve used it on messes in carpet before and it seemed to work. Still, I had no idea if it would do anything to gum, but I didn’t know what else to do, so I tried it.
I gave the gum good coverage with the foam and let it sit (I pretty much just let it sit until the foam fizzed away, so 30 seconds or so) then scraped it with a knife. The liquid that was scraped up on the knife was a pinkish brown and the gum was red, so I figured I was getting somewhere. I wiped the knife on a paper towel after each scrape and pretty soon, it looked… clean! After spending twenty minutes with ice and getting nowhere, it took me about five minutes with the Zout stuff, and that’s only because the gum was spread around and stuck in four or five different spots.
Of course, then I wiped up my workplace on the dining table with rubbing alcohol and took half the rooster designs off. Oops!
