Last night after two days of waiting for my airlock to start bubbling, I noticed that the grommet that seals the airlock was push partially into the pail. When I removed the airlock to fix it, the grommet fell in. The only way I could get it was to go in with my arm. I did wash my arm really well before doing this, but I really don't know how sensitive this stuff is to contaminates. Did I just ruin this batch?
