Brown Scum Test with Plumber's Silicone Grease

I conduct a brown scum test using a daub of plumber's silicone grease to observe the brown and scum formation during hydroxy electrolysis.



I conclude plumber's silicone grease does not contribute to the formation of scum and may not contribute to the formation of brown particulate.

A side observation is that the grease is unaffected by temperatures of 150F.
