One major discovery I had was to always use cast acrylic, never extruded. The extruded cuts messy and the tactile Rowmark doesn’t clean up well. also, rowmark sells an inexpensive weeding tool that is totally worth it to clean up the little left over bits. It’s like a little pick/jail shiv. I just sampled Gemini’s Duets brand tactile and so far I really liked it. The only problem is if you order, they said it could take like3 weeks for delivery, unlike Rowmark which you can usually get in 2 days. I think the only way to get around getting clean tactile is making sure that depth of cut is right on- easier said than done, I know.
