That's cheap q-tips for you! They are made of cellulose and react with the ca. If you have enough cellulose based cotton wool and enough ca you can cause spontaneous combustion! There are a few fake magic tricks showing that on YouTube. You need to get pure cotton ones, Johnson's are good in the UK, don't know about elsewhere.
Also don't use quick drying ca. I use some foam friendly flexible ca that also doesn't go white and takes a couple of minutes to dry. Works great and less likely to tweak the chassis at all.
