I'm hoping for a little wisdom to explain what I'm seeing when I scrape my kids' skis. Note that I don't see this when I scrape the grown-ups' skis.
I'm using a sharp 6mm plexiglass scraper. The skis were waxed with Toko S3 Red hydrocarbon wax. They sat for at least 10 hours before scraping.
The black part of the ribbons doesn't seem to me to be just dirty wax. Unlike the normal scrapings, which are dull and delicate, the black scrapings are shiny and have some tensile strength.
So, is it possible that I'm scraping P-Tex off? Or, could the act of waxing be bringing something out of the base that combines with the wax? My gut feeling is that this is more than just dirty wax. I keep my iron set to 120 degrees Celsius and the wax does not smoke. I don't think base material melts this low. The kids' skis are Blizzard Viva Jr. and Atomic Sweet Stuff.
I'd be grateful if anyone can tell me what's going on, if it's a problem, and what the best practice is regarding it. Thanks in advance.
