I've never used petroleum balls to catch a spark,' I've always used a lighter or matches with them. I've used sparks on plain cotton balls. Now I've taken to injecting semi liquid vaseline into the center of cotton balls with a 22 gauge needle. It works very well, no messy, and plenty of surface material to catch tiny sparks, with fuel inside. have yet to use one under harsh conditions but has never failed in our testing.
I hadn't tried to fluff the jutte I worked with so that's probably why I've never had success. Thanks for the instructional.
