Good Cooks brand solid silicone scrapers and spatulas. The kind that are all one molded piece so they are easy to clean. My weapon of choice for emulsion and wb inks. You can scrape the inside of the buckets clean to reduce dried emulsion and ink film.
How does the silicone react with ink cleaners.. in case someone decides to whip up some plastisol with them.
