I am by no means an expert, but what I have done in the past is that fortunately my CCM blocker had a zipper along the top where I could take the foam out (the zipper mechanism part is small and recessed that I needed a very thin needle nose plier to get at it).
I then made a simple bath using Lysol's product, but I imagine Oxyclean does similar things. I placed a weight in the blocker to keep it submerged and left it there over night, and then rinsed it until the water ran clear. Then placed it on a boot cleaner for about a day's worth of time.
For the glove, I did the same thing as the blocker, and then while it was wet, I used hot water to break it in some more while I was at it.
Chest and pants, I placed it in a no-spin cycle with the Lysol's laundry additive, air-dried it afterwards hanging (making sure all the velcros were strapped).
