Does Hydroton ever become fully clean? A.K.A. No More Red Dust!

[emmajs243]

Ok guys, I have read all the posts just about on HOW to clean Leca beads, specifically hydroton, read Rays website on cleaning and prepping media....FYI not talking sanitizing used LECA for reuse JUST prepping new LECA.

I have soaked it for a few days with Epsom salts, hand agitated it more times then I can count, boiled it, and I swear, the stuff still had red dust to put out! I have seen some on YouTube saying a good boil really gets all the red dust out so it doesn't smudge the inside of the containers but so far, I don't see it.

Has anyone else had success with boiling and the majority of the red dust actually being gone? If so any tips? I am wondering if maybe I am boiling too much at once so it isn't get as equally agitated and maybe there isn't enough water so the dirt to water ratio is primarily just boiling in dirt? I don't know it's just the only thing I can think of.

Experiences??
