Mold on potted mushroom substrate

Apparently I have sinned.
I decided to try growing my own table mushrooms. got some (innoculated?) wooden plugs from Ebay,, got distracted, put the whole , unopened bag in the fridge & forgot about it for 8 or 9 months.. cooler weather came along, more time available, tried growng shrooms on coffee grounds & in other pots on shredded cardboard.
I used msc plastic containers to hold the substrate. cleanliness is probably abominable, I just washed plastics , and the old styro ice chest that houses my "farm" in the kitchen sink, then rinsed with a bleach solution ( roughly 10%) . Since I only wanted a few mushrooms at a time, I used small individual containers ... cut off quart milk jug bottoms, individual serving yogurt cups, coffee "cans" ( they have a nice handle). plus, since one of the criteria for fruiting seems to be "(complete consumption of the substrate)" , the smaller packages should be ready to fruit rather quickly.
well I thought it looked like the first pot ( coffee grounds) was ready to fruit, I took it out of the ice chest, put it in a loose plastic bag, put it in the fridge for a day, then moved it to the ( east facing) window sill over the kitchen sink. took it out of the bag & waved it around 3x a day, then back in the bag.
then it looked like the substrate was drying out, it was shrinking away from the edges of the milk jug, so I started flicking a few drops of tap water onto it as I aired it 3x daily.. I did not see mushroom pins starting, but I did see patches of mold. ICK.
I checked the rest off my "farm" pots, looks like mold is every where. I dumped the contents of all the pots into the garden mulch bin.

Before I start over, how many "sins" can you spot in this story?
what is the "proper way" to sanitize mushroom growing equipment?
Thanks, CE
 
My previous laptop never exploded like that. Read this tiny ad while I sweep up the shards.
