Question by austhome7: What cleaners can I use that won’t hurt a worm farm that’s used to get rid of wastes underneath it?
My sister is going to have a kennel for dogs and the council want a waste disposal system that’s looked after by worms and they want to know which chemical cleaners are safe to use that won’t hurt the worms.
I know I’m in the dog section for they’re going to have a kennel and the worms are supposed to get rid of the dog’s poop somehow.
