Using a rice cooker to clean hydroton?

Hello everyone as the title suggests I'm using a rice cooker to clean hydroton. I plan to bake it for a hour at 400F afterwards to steralize it for sure. At first I tried baking it but it started stinking pretty bad from the salts trapped inside I guess. I pulled it out fairly quickly and have about 5L of hydroton cooking in a rice cooker at about 200F verified with a fryer thermometer. It stinks as it is and I have it in a back bedroom next to a window with a fan blowing outside. I'd boil it on the stove but I don't want to stink the kitchen up again. I have a few questions about how I should do this. First how long should I cook it in the rice cooker? Until it stops smelling? Secondly should I add bleach and if so how much? And lastly should I leave the lid off so the steam and odours can escape? Thanks for any help on this

There are plenty of threads on here a bout how to clean hydroton. I myself have answered this at least twice.

I will tell you this though: You're making it too complicated.

there is no need to cook or boil it, I use h2o2 myself, some people use bleach

K.i.s.s......
