How to Clean Photo Emulsion Out of Screen
Photo emulsion is a chemical used during the silkscreen process that transfers an image onto the screen. The silkscreen process is achieved by combining artwork, the photo emulsion, heat and light. The image may not fully transfer to the screen as a stencil if the screen is under- or overexposed to the heat and light or if the artwork is prepared correctly. Removing the photo emulsion cleans the screen for further use.

Remove the screen from the bleach and rinse the screen with hot water. If your sink has a spray attachment, use the highest amount of pressure that the hose reaches. Scrub both sides of the screen with the brush and detergent for dishwashers. Rinse the screen with hot water. Allow the screen to dry.
