How to Remove Chewing Gum from Concrete
Chewing gum has to be one of the most annoying inventions ever made. It sticks to everything that you wish it wouldn't, including concrete, and then is very difficult to get off. Spying a piece of dirty chewing gum on your walkway can make you grind your teeth in fury, but once it is there, there's nothing that you can do except try your best to get rid of it. However, taking chewing gum off of a concrete path or driveway does not have to be a day-long chore. You need to do a little bit of scrubbing, and have some patience, but you will soon be able to get rid of the gum with a few household utensils and some helpful guidelines.
Step 1 - Dry Up the Gum
Before you can get rid of the gum, you need to make it harder and dryer. While it is still soft, it can stick to almost anything with great force, so you will have to begin by freezing it. Use an ice cube to make the gum cold, or try one of those freeze-dry aerosol cans which can be bought from mechanics' shops. This will make the gum solid for long enough to scrape it up quickly. You may have to freeze the spot more than once in order to get all of it off.
Step 2 - Scrape the Top
After it is made dry and brittle, you can dislodge the gum from the concrete with an old putty knife. Saw at the edge of the spot until it starts to come loose; then, it should come up fairly easily. As mentioned previously, you may need to repeat the first step a few times in order to keep it hard enough to scrape. However, if you are unlucky, you may end up having the gum snap off while leaving small pieces behind on the concrete. In this case, continue on to the next step.
Step 3 - Wipe up the Rest
You can add a little bit of WD-40 to your tools for this job. Spray this directly onto the gum, and allow it to sink through for one or two minutes. After the proper time has passed, you should be able to use the putty knife to scrape away the remaining pieces. Be sure to dispose of the gum carefully once it has all been removed. Otherwise, it may end up right back where it started.
Step 4 - Clean Off the Concrete
In order to remove residue which may be stuck in the tiny pores of your concrete, you should take a small pot of vinegar, and cover the area where the gum was. Scrub the vinegar into the spot with an old toothbrush to dissolve any particles left behind. Leave it for about five minutes, and then scrub over again using some water.
When you're completely finished, you can clear away any chemicals or vinegar that remains by using a pressure washer to hose down the driveway or sidewalk.
