can you rejuvenate colloidal silver?

[VARick]

I searched online and was not able to find an answer. Due to some health issues my growing ceased for a number of years. I was going through my supplies on hand and found a bottle of 240ppm colloidal silver. My laser pointer crapped out as well so can't see if there is anything still there. Bottle was stored in a cool dark location. Any idea if I'm just out of luck here or can I maybe resurrect something? Since it has been awhile since growing, reading through the forums has shown me alot has happened in just a few years, so looking forward to learning again. Thanks in advance and to those who willing share their thoughts and knowledge here.

More than likely it is well past its prime. Without a laser pointer, your kinda in a rough spot...
I'd suggest just making a batch yourself. Simple and cheap (compared to purchasing) all that is needed is a low voltage DC power source (I've used 3- 9v batteries in series), a couple alligator clips, and a silver coin. I use an old us quarter, it is 90% and works fine for our purposes. (I personally would not consider ingesting any unless using sterling or 99%)

Current setup is an old wall charger with the 2 clips attached. Takes about 12 hrs till done.

Lots of videos on YT on the process, but you'll still need a laser for checking...
