Making CDS

Hi, I am making a batch of CDS and I am asking for information. 1) it doesn't seem like the distilled water ever gets to the same color as the glass that I put the 100ml of mms & activator in. Also what can I use the remains of the activated MMS for. Do I discard that or is there a use for it ?  TYIA
 

The remainder can be diluted and used in a spray bottle for disinfecting countertops and such.

I make a small batch of CDS every week, and the distilled water doesn't get to the exact same color as the shot glass. When my process is done, I reuse the shot glass of activated MMS with fresh distilled water and let it go another day or more. The resulting CDS is only around 100 ppm, but that's fine, as I usually drink it at around 50 ppm. I just add it to 8 oz. of water and drink it over the next few hours. The remains in the shot glass I discard.
