Here is a thread that discusses this… Has some good info… I am interested to hear new info as well.
Tools for cleaning up cuts - Langmuir Systems Forum
For dross removal I use the fireball tools scraper https://fireballtool.com/products/fireball-scraperor or a masonry chisel. Sometimes I go over it with a die grinder… usually just scrape the dross and sand it and call it good.
I do a little more prep with the dimensional stuff then the artsy stuff.
