It really doesn't say anything about the utensils used in the prep of the substrate. How clean do they have to be? Do they need to be boiled or is a simple soap and water cleaning good enough for them?

you do not have to use vermiculite in such a way as to cause direct contact with the mycelium. i personaly use a coaster to place the birthed cake on and use vermiculite soaked in a 90% distilled water and 10% hydrogen peroxide mix (the hydrogen peroxide helps keep the vermiculite from getting funky smelling) in a bowl in a terrarium with a tight fitting seal and air it and mist it  2 to 3 times a day with the same water mix used above. have had fantastic results with this method and no contact with the vermiculite has ever occurred. good luck :mellow:

...Im NOT talking about that. You have to mix the vermiculite with water and brown rice flour to create a substrate in which you inject the spores. The shrooms then grow from that substrate.

PF - Tek / how long do syringes last?

I purchased a couple spore syringes a month ago. Haven't used them yet as they are sitting in my drawer. Is there a time limit and how should the syringes be stored?

Do you have to sterilze everything such as the jars, bowls, spoons and all equipment used for the preparing your substrate??? Do you have to prerssue cooks these things or would simply washing them be good enough?
