Hello!
I have been told that you can take out all the dirt frome the earthworms by leaving them for 24 hours in a bucket with moist napkins in little pieces (without ink or perfume). I have done it and after this treatment you cant see the dirt that is usually seen in earthworms has disappeared.
By the way, I dont know if anybody can help me with this, I am going to take my earthworms to a bigger place, so I bought two buckets, and they have a rather nasty plastic smell. I washed them very well, and they leached some jelly stuff, so I called the manufacturer and told me it was some kind of acrylic, non toxic, but the smell hasnt disappeared totally... is it safe to use it?
