I'm experimenting with as many solvent-free (Correction: Naptha/Hept/Hexane-Free) teks as I can to help people understand the best options that adhere to the laws in Colorado, which don't allow use of anything with a flashpoint under 100F (except IPA, which is allowed). If you consider yourself an expert in any teks that don't use naptha, heptane, hexane, etc and instead use limonene, alcohol, or just boiling, please share them here. I've tried all of the teks listed in the Nexus and a couple others, and tonight I'm trying BLAB (the Big Leisurely A/B) and my own STB variation of that with Limonene, trying to find (or create) a tek that doesn't require immense amounts of wasted alcohol or over a week to complete.
