Colloidal Silver Testing

Colloidal Silver I have had lots of requests to determine if colloidal silver kills germs. So, I tested ASAP 10 Silver Solution and Bio-Silver Ultra Colloidal Silver . I did the experiments on the countertop just like the cleaning product experiments. I used .5mL of each silver and let it sit for 5 minutes. You can read the full procedure here.  I did not detect any significant bacteria killing ability from these silver products. This does not mean that they don't kill any germs. My experiments have a lot of dirt and a lot of germs. A product has to be really powerful to look good in my experiments. So, there could be a small amount of germ-killing going on that I can't detect. Also, it is possible that the colloidal silver takes a lot longer than 5 minutes to kill germs. This experiment just compares it to the bacteria-killing power of hydrogen peroxide.
