Eight smart uses for vinegar

Now that you know ketchup can be used for shining copper and repairing hair, or that vodka can be used to repel insects and freshen laundry, you may have been wondering what tasks you can get done for cheap with other household items.

Since May is National Vinegar Month (did you forget?), we thought we’d take a closer look at this inexpensive, versatile good.

According to the Vinegar Institute, the useful stuff was probably discovered by accident (most wine drinkers know what happens when you leave a bottle sitting around too long). In fact the word vinegar comes from a French translation for “sour wine.”

Over the centuries vinegar has been produced from many stocks, including molasses, dates, sorghum, fruits, coconut, honey, beer, maple syrup, potatoes, beets, grains, and more. But the principle is the same: You get acetic acid (a.k.a. vinegar) after first fermenting natural sugars to alcohol, and then fermenting again.

As Michael de Jong, The Daily Green’s Zen Cleaner and author of the Clean series of books, points out, vinegar has been pressed into service for many uses over the centuries. It has been prized as a foodstuff, condiment, preservative, and natural remedy.

What’s so great about vinegar? Besides being effective, vinegar is cheap and widely available. It is nontoxic and lasts for a very long time without losing strength. It does not pollute land, air, or water, and it doesn’t combust. It’s much safer to have under your sink than bleach, ammonia, or other toxic cleaning products. Many folks also swear by the benefits of apple cider vinegar.

In the spirit of green cleaning, green thrift, and green creativity, we put together this list of alternative uses for vinegar. Add your own in the comments!

Cure hiccups

Some have said they were able to cure pesky hiccups instantly by swallowing a teaspoon of vinegar. Most folks use white vinegar, but people have also reported success with apple cider, balsamic, and rice varieties. So you have a few options as far as taste and aroma. Hey, if the Roman legions drank it, it must be good for you, right?

Fight cramps

If you often get foot or leg cramps in the middle of the night, you may want to try boosting your potassium levels. There are a number of great superfoods rich in potassium (way beyond bananas). Some folks have also suggested trying this remedy: Mix 1 tablespoon of apple cider vinegar, 1 teaspoon of honey, and a cup of hot water. Then drink before bed. Yummy!

Break bad bonds

Having trouble getting that annoying sticky label residue off a product? Or accidentally glue something together? Vinegar can be used as a solvent to dissolve many common adhesives. Vinegar is also good at cutting grease. 

Deter cats

We love cats (even LOLcats!). But sometimes you don’t want them doing their business in the kids’ sandbox or in your flower bed. According to HomeEnvy, a simple solution is to pour vinegar around the edges of the area you want to protect every few months. 

Wash produce

According to the green team at Ideal Bite, vinegar can help remove bacteria and pesticide residues from fruits and veggies. Mix three parts water to one part white vinegar, and dispense in a spray bottle. Then rinse with water. The site claims this wash kills 98% of bacteria on produce. 

Clean windows

Instead of spending money on window cleaning chemicals — especially ones that include toxic or potentially toxic chemicals — make your own! Mix 2 tablespoons of white vinegar with a gallon of water, and dispense into a used spray bottle. Squirt on, then scrub with newspaper, not paper towels, which cause streaking.

Get spring-fresh laundry

Got grass stains? No problemo, says Michael de Jong. Make a mixture of one-third cup white vinegar and two-thirds cup water. Apply the solution to the stain and blot with a clean cloth. Repeat this process until you’ve removed as much green as possible, and then launder as usual.

When your big washing day comes around, toss in a capful of white vinegar. Your colors will come out bolder and your whites whiter. If you’ve recently had an encounter with a skunk, it will take more than a capful.

After washing, get a sharper crease in pants by dipping the cloth in a 50/50 mixture of vinegar and water. Then wring out the cloth and press the creases. Now you look like Dilbert! 

Clean carpets

According to this The Daily Green community member: “Spots in carpets often remove with a simple dilution of one part vinegar, one-sixteenth part lemon juice, and eight parts distilled water.”

User photographs can still be found on many social networking sites even after people have deleted them, Cambridge University researchers have said.

_45803226_44193809They put photos on 16 popular websites – noting the web addresses where the images were stored – and deleted them.

The team said it was able to find them on seven sites – including Facebook – using the direct addresses, even after the photos appeared to have gone.

Facebook says deleted photos are removed from its servers “immediately”.

 

The Cambridge University researchers said special photo-sharing sites, such as Flickr and Google’s Picasa, did better and Microsoft’s Windows Live Spaces removed the photos instantly.

You may have put your pictures in Facebook’s bin, but you will still have to wait for the content delivery network to delete them

To perform their experiment, the researchers uploaded photos to each of the sites, then deleted them, but kept a note of direct URLs to the photos from the sites’ content delivery networks.

When they checked 30 days later, these links continued to work for seven of the sites even though a typical user might think the photos had been removed.

Lazy approach

Joseph Bonneau, one of the PhD students who carried out the study, said: “This demonstrates how social networking sites often take a lazy approach to user privacy, doing what’s simpler rather than what is correct.

“It’s imperative to view privacy as a design constraint, not a legal add-on.”

But a Facebook spokesman defended the company’s approach saying; “When a user deletes a photograph from Facebook it is removed from our servers immediately.

“However, URLs to photographs may continue to exist on the Content Delivery Network (CDN) after users delete them from Facebook, until they are overwritten.

“Overwriting usually happens after a short period of time.”

Users of Facebook staged a revolt recently over rules which would have given the site permanent ownership of their data.

 No such thing as “deleted” on the Internet.

It’s always fun to write about research that you can actually try out for yourself.

Try this: Take a photo and upload it to Facebook, then after a day or so, note what the URL to the picture is (the actual photo, not the page on which the photo resides), and then delete it. Come back a month later and see if the link works. Chances are: It will.

Facebook isn’t alone here. Researchers at Cambridge University (so you know this is legit, people!) have found that nearly half of the social networking sites don’t immediately delete pictures when a user requests they be removed. In general, photo-centric websites like Flickr were found to be better at quickly removing deleted photos upon request.

Why do “deleted” photos stick around so long? The problem relates to the way data is stored on large websites: While your personal computer only keeps one copy of a file, large-scale services like Facebook rely on what are called content delivery networks to manage data and distribution. It’s a complex system wherein data is copied to multiple intermediate devices, usually to speed up access to files when millions of people are trying to access the service simultaneously. (Yahoo! Tech is served by dozens of servers, for example.) But because changes aren’t reflected across the CDN immediately, ghost copies of files tend to linger for days or weeks.

In the case of Facebook, the company says data may hang around until the URL in question is reused, which is usually “after a short period of time.” Though obviously that time can vary considerably.

Of course, once a photo escapes from the walled garden of a social network like Facebook, the chances of deleting it permanently fall even further. Google’s caching system is remarkably efficient at archiving copies of web content, long after it’s removed from the web. Anyone who’s ever used Google Image Search can likely tell you a story about clicking on a thumbnail image, only to find that the image has been deleted from the website in question — yet the thumbnail remains on Google for months. And then there are services like the Wayback Machine, which copy entire websites for posterity, archiving data and pictures forever.

The lesson: Those drunken party photos you don’t want people to see? Simply don’t upload them to the web, ever, because trying to delete them after you sober up is a tough proposition.
