I am SO sorry for your trouble!
This is a perfect example of why I personally don't ever use those blue (or purple) wash-out/air-out pens. To my way of thinking, for our purposes, there is no anti-matter....the stuff *has* to go some place! It might not be the correct wording, but I call this stuff "fugitive" because it's always hiding somewhere.
Hope you are able to find a good solution.
