The rubbing alcohol is for sterilizing your hands and your jars.But I'm a total newbie so I'm just telling you that this is the way I'd do it. I'd use my pressure cooker to make a batch of wild bird seed grain spawn over the next two days(that's how long the procedure takes for me). After they are finished and before you take the prepared wild bird seed spawn out of the pressure cooker I'd prepare my glove box. The one I use is one I made out of a 51 quart rubbermaid tote fitted with two glory brand canned turnip greens cans attached with epoxy to the box. Then I've taken the longest, largest vinyl dishwashing gloves I could find and glued them to the cans. These help keep your arms from getting sore from resting on the cut edge of the plastic box. Then I've taken silicone sealant and applied it to the entire top edge of my box. To make it airtight when it's closed. To test this I put a burning candle in it and when it runs out of oxygen I can see it's air tight. Then when everything is inside the box I spray it all down with the rubbing alcohol. Don't forget to fold up a couple of paper towels and put them in the box too. This will help wipe the excess alcohol off of everything before you remove the lids from the jars and open your spawn. I can fit 12 quart jars and one 2.5 bag of sawdust spawn in it. I make sure it's clean. I have a misto sprayer I fill with alcohol and it fits nicely in my glove box along with the prepared jars and my spawn. I just started growing mushrooms and since I've started everyone of the things I've inoculated has colonized perfectly. This isn't brain surgery no matter how technical it seems. K.I.S.S is best.
