I print in my garage, nothing fancy, and made a "washout booth" out of an oil drip pan. When I'm done printing I get most of the ink off the used screen and when I reclaim I just put the drip pan up against the side of the house and power wash it with the proper chemicals. I use speedball ink and murakami emulsion and it's kinda starting to make a little bit of a mess on the side of the house. Any tips for removing these ink and emulsion stains on the brick and concrete?
What tufty said. Then when you are done with the cleaning let everything dry off from the power washer for a minimum of a week and the give all then surfaces 3 coats of anti graffiti paint to make it easier the wipe down in the future.
