There's usually no such thing as a "magic bullet" fix... but sometimes, there is a company or a machine or a process that can seem to come pretty close. As we've seen, there is a lot of work going into solvent reformulations, coatings, etc to reduce toxicity, and a lot of chemical engineers at the BASFs and DuPonts of the world working on better solutions. Have you had any chemical or solvent substitution "wins"? Either a straight material swap or a material swap with a new process?
