Okay, so here are all my supplies I need for sterilizing/sanitizing the boys' nebs.
Every time the boys finish a treatment, I wash off their nebs a bit and put them in a separate pasta strainer. I can fit 8 nebs inside this one. I love these things, I can store the used ones in them and then just lower them into my huge pot. I take out the fish masks, as I am afraid they will completely fall apart. I make sure the nebs are completely submersed in water, put a lid on and let them boil for 15 minutes. Water here takes about 25 minutes to boil, so I put a timer on for 40 minutes and I am free to do some other chores.
Once my timer goes off, I very carefully drain out most of the water and then with the lid on I shake the rest out over the sink.
After the 30 minutes are up, I put the nebs back together and store them in this wonderful little storage container.
