A word of caution on "deactivating" primers.
Most primers on the market today are very resistant to contamination that may kill them. A couple of years ago I tested this by placing 10 Federal large rifle primers in a zip-lock bag and gave them a good shot of WD-40. 3 days later I took them out and rolled them on a towel before loading them in 30-06 cases. I then shot these primer-only cases in one of my rifles and all 10 popped.
The point I am trying to make is don't assume a drop of oil or water will render a primer "safe".
