I have used my walnut shells for years by cleaning it with liquid dish soap
I put it in a bucket add soap and hot water stir it round and strain it with
a pair of my wife nylons several times adding water stirring and straining.
Then I dry it behind the wood stove in a pan turning it and shacking it
once and while until dry . works for me .You will be surprised how
black the water will be keep doing it until clean water .
