How to Recycle Dental Floss Tutorial

1944gg0065r I’ve talked before on my blog about my frugal grandmother.  Grandma lived through the Great Depression and as a result she was extremely frugal for the remainder of her life.  I remember going to her house after dark and every light was turned off except for one small bare bulb lamp in the kitchen.  She always kept a dish washing tub in the kitchen sink and collected water there to flush the toilet at the end of the day.

She taught me a lot about frugality, and one of the things I learned from her as a teenager has saved me thousands of dollars over the last three decades and today I’m going to share it with you.

Materials needed for this recycling project –

Step one for this project.  You need to have someplace attractive in which to store your used dental floss.  Grandma used an coffee can with a slit cut in the top but I like to use this pretty pink trash can.


No one will ever guess what’s inside, unless they get nosy and look.  And then it’s their own fault for being nosy.  Amazon has this Umbra Mini Recycled Polypropylene Waste Can which is very similar, plus it is also recycled from polypropylene!  My grandmother would have been so proud of me.

Floss Recycling Technique

All right, let’s get started.  As you use your dental floss try to be a little more careful than you normally are with it.  Try not to break it in half as you are jamming it in between your teeth.   Grandma actually used to tie broken and torn pieces together but I decided to skip that step and I’ve still saved thousands of dollars in the last three decades.  No telling how much money Grandma saved over the 93 years she was alive.  If you wish to follow Grandma’s lead, just trim the frayed ends and tie a double knot.

As you use your floss, tuck it into your recycling bin.  I usually wait about two or three months to process one batch.  Of course you could process more often but it is kind of a lengthy process so I like to wait until I’ve gathered up a big mass of floss.  I actually like to call it my Floss Moss.

When you’re ready to clean a batch, I always recommend using a good pair of tongs. I have a pair that I use for this purpose alone.  If you don’t use tongs, then you must at least use protective gloves because the bacteria that has been festering and growing on the floss in the last few months is practically a biological hazard at this time.

Wash your kitchen sink and fill with hot soapy water.

Next grab the mass of floss with your tongs.  With practice you will find you can grab the entire mass at once.

Remove the bag from the recycling bin and throw it away.  Replace the bag with a new one.

Drop the entire wad of floss into the soapy water.  Continue to use the tongs and swish the floss around in the water.

Remove the floss using the tongs and drop into a colander which has been set aside for this recycling process.  Or you can sterilize your regular colander after usage.  I recommend having a colander used specifically for this recycling project.

Rinse with hot water from the faucet.  Allow to drain for a few minutes.

After removing the floss, be sure to wash your sink with detergent and perhaps a few caps of bleach to disinfect it.

Still using the tongs, pick up the soggy wad of floss from the colander and place in a pan of water.  Turn the heat to medium high and bring to a rolling boil, with the tongs in the water. This will also serve to disinfect the tongs for later usage.

Reduce heat to a simmer and allow the floss to simmer for exactly 10 minutes.  Any longer and you degrade the fiber, any less and you don’t kill the biological hazardous bacteria.

After 10 minutes, use the tongs to remove the floss and lay it out on a thick clean towel.

This is an optional step.  You may wish to skip past this one as Grandma did not use it, but I have incorporated over the years.  I feel that using an ultrasonic cleaner is just one more step closer to getting the floss sparkling free from bacteria.  Just stuff the floss into the device, fill with water until it’s covered and turn it on.  Mine only runs for two minutes and I let it go through ten cycles.  I just set a timer for 2 minutes and go back in and turn it on for another two minutes.

Okay, now go ahead and lay the floss out on a clean towel.  Now you will begin the process of sorting out and detangling the floss into straight pieces.

When you have about ten pieces in a long straight section, place aside.

Once all the floss is detangled and straightened, you will need some way to dry it.  Grandma used her clothesline and I use mine as well.

I usually put up a heavy blanket on two outer lines and place my floss on the inner line.  This is to prevent neighbors from asking what that is on my line like they asked Mrs. Money at Ultimate Money Blog about her family cloths.  Allow the floss to dry in the sun which will ensure that it is completely dry for storage.

After a few hours, carefully remove the floss from the clothesline and bring it inside.

I lay another towel out on the table and pull out a piece of aluminum foil, and parchment paper – longer than the length of the floss.

Lay the pieces of floss into a stack on the parchment paper. You might want to snip the one end so that it is neat and tidy.

Floss Recycling Technique

Chip off a few pieces of the paraffin wax into a shallow pan and heat until melted.  Drip wax across the length of the floss. Just about 20 drops here and there is good enough because you will be pulling the floss through to the end and the wax will lightly coat all of the floss.

Next you can use some kind of organic mint oil to drop across the length of the floss to give it that minty, fresh taste.  I prefer Now Foods Peppermint Oil Certified Organic.

After you’ve dropped on about ten drops of mint oil, fold the parchment paper over the floss several times.

Finally, wrap the aluminum foil over the parchment paper.  Leave one end open so that you can grab onto a piece of floss and pull out one at a time.  It takes a little bit of practice to get used to the method but it will definitely be worth it when you see how much money you’re saving on floss.

And there you have it.

I would love to hear from you in the comments if you have ever heard of this Floss Recycling Technique by any of your older relatives. I have asked around and no one has ever heard about it.  I think my Grandma might be the genius inventor of this technique and I’m beholden to her for teaching me all about it.

Thanks for reading and please share with your friends and family and on your social networking groups so that everyone can learn this fabulous method and save themselves a bundle of money.
