We've been receiving a lot of phone calls and emails about our clean up practices with oil based inks. So, here is a overview. We use Vegetable Oil and Simple Green a non-toxic, biodegradable cleaner and degreaser. With a rag we remove the ink using vegetable oil. Then we use another rag and remove the left over oil by spraying Simple Green and wiping all oiled surfaces down. Below are directions we used for our Letterpress clean up, drawn by the one and only Arley-Rose Torsone. If you have questions, email us, we're happy to share and love to learn about other shops.
