I gave up using H202 to add to CS Dan, as all I got was murky sludge!
I used 3% stuff. dee

In the past it has been difficult for me to make completely colorless
CS of a reasonable concentration. While the CS was clear, it usually
acquired a slight yellow tint. I initially blamed this on the
distilled water, but I think the actual culprit was the H2O2 that I
was using to clean the electrodes and cell. I intially thought that I
had H2O2 without stabilizers but realized that it did have stabilizers
in it (very small print). Also, when I added this H2O2 to clear the
CS after it had been made, it often turned cloudy and took at least
twice as much as everyone else was talking about using to clear it.
After getting a bottle of 35% food grade H2O2 without stabilizers, the
CS clears readily with the added H2O2. I haven't made a batch of CS
since I got the new H2O2 but I suspect it will be easier to get
colorless CS now, right from the start...
