While googling benefits of copper I came across a "DIRTY HIPSTER ARMPIT TOOL" which is only a copper-plated tongue scraper at over $20. Not a pure copper tongue scraper like here on Gaia Guy for under $10.
However, what really intrigued me was it being sold as an odor causing bacteria fighting and lymphatic drainage tool. Say what?
OK so you may be able to use a copper tongue scraper to assist in that type of massage and it may have some benefit. Here's a quick video on that and you can google on and on to learn more about lymphatic massages.
However, let's get back to why we love copper for our tongue scrapers and not stainless steel. Stainless steel doesn't kill bacteria like copper does and the scientific proof is below. Let's also refresh our knowledge of what copper does and why it may kill the bacterium Staphylococcus hominis, which makes human armpits smell.
When Escherichia coli (E. coli) and photo-bacteria were used as samples, the antibacterial effect of stainless steel was very weak, while the percentage of bacteria dying from exposure to metallic copper for 30 min was over 90%. Source
Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. While the phenomenon was already known in ancient times, it is currently receiving renewed attention. This is due to the potential use of copper as an antibacterial material in health care settings.

Copper has potent biocidal (kills organisms like bacteria) properties. Now you may be saying is it safe though? Copper is a very weak sensitizer as compared with other metal compounds, and the risk of adverse reactions, due to dermal contact with copper, is exceptionally low. Source
Copper like the pure one used in Gaia Guy's Zero Waste Oral Hygiene Kit has excellent antimicrobial properties. Hospitals are using copper surfaces in high touch areas both by staff and patients and this resulted in diminishing bacterial surface-loads up to 90% as compared to controls. Source
OK, it is clear that copper has some amazing benefits for our skin and health, but will it stop B.O? Well, incredibly the reviews on that rather expensive copper armpit tool seems to suggest yes.
As copper is safe you may as well give it a try. You could give your Gaia Guy copper tongue cleaner a try or pick up another one so you don't get any lingering and odd tastes on it. :)
Love to hear if this works so leave a comment below after trying for a couple of weeks or so.
