SC-501, SC-505, SC-507
Screen Cleaners: Murakami screen cleaners cover any screen cleaning need. These screen cleaners form part of a system of screen preparation products designed to prepare mesh for a new job.  Available in gallon, 5 gallon and drum containers. More>

  • SC-501 is water soluble and designed to perform multiple jobs.
  • Use as: a press wash, screen opener, ink wash up, or in a re-circulating parts washer.
  • Excellent for enamel, epoxy, vinyl and plastisol ink systems.


  • SC-505 is best suited for clean up of plastisol and UV inks before reclaiming emulsion or putting the screen into storage.
  • This product can be used in a re-circulating parts washer.
  • SC-505 can also be used to remove pallet adhesive on textile presses.


  • SC-507 is a water soluble all purpose cleaner.
  • This product can clean many different types of inks: Lacquer, Vinyl, Mylar, Polypropylene, polyvinyl chloride, acrylic, poster, solder mask, epoxy, and water based inks.


Haze Remover
Screen De-hazers: Previous print runs can stain mesh with the print image.  This image can affect the coating of emulsion or show up in the next print run as a ghost print within the new print.  De-hazers remove these images from the mesh and leave it ready for coating.  Recent print runs can be removed with HR-701, for very difficult to remove images HR-700 is a stronger alternative.

  • HR-700 is a caustic haze remover that requires the following protective gear: Safety goggles with face mask, Full length Nitrile Industrial Gloves, Rubber Apron, and no open toed shoes.
  • Apply for 5 minutes and remove to prevent mesh damage as this product is caustic enough to damage mesh.
  • Rinse with water when done, avoid splash back of chemistry.

    TECHNICAL DATA SHEET  |  Material safety data sheet

  • HR-701 is a non caustic haze remover.
  • Use of personnel protection equipment is always recommended in screen reclaiming.
  • Apply to screen on both sides using a soft bristle brush to work into mesh.
  • Rinse completely prior to applying emulsion remover.


Emulsion Reclaiming:  Murakami emulsion removers can be purchased in a ready for use, a concentrate, or as SMP powder for reclaiming.

  • ER-601 is a ready for use emulsion remover.
  • Apply to both sides of screens and allow to sit for a few minutes to soften emulsion for reclaiming.
  • Can be used in a re-circulating parts washer.


  • ER-605 is a concentrated emulsion remover that is mixed with up to 30 parts water to 1 part of ER-605.
  • ER-605 can also be mixed in a concentrated form  for stronger solutions.  15:1 is commonly used for water base and discharge screens to overcome the emulsions that have been hardened for these agressive ink systems.
  • Super Strip-P mixes with water to create emulsion reclaiming chemistry.
  • Mix to desired strength.
  • Available in 1 lb and 50lb packaging.


DGR-801 Screen Degreaser
Murakami Degreaser

  • DGR-801 is formulated to clean the mesh of contaminants and leave the mesh PH balanced.
  • DGR-801 helps the emulsion coat and adhere better than standard degreasers or off the shelf products.
  • DGR-801  can be mixed 1 part product to 1 part water to extend usage.

    Technical Data Sheet  |   MSDS Request

  • MS-Degreaser is a new degreaser from Murakami that has improved performance to remove stubborn contaminants and improved cleaning properties to leave mesh in optimum condition for emulsion coating.
  • MS degreaser can be diluted 10 parts water to 1 part degreaser.
  • Promotes better adhesion and emulsion coating qualities.
  • Limits fish eyes and pinholes dramatically.
  • Excellent screen prep for capillary film, thick film and all emulsions.
  • Use a natural sponge instead of a pad or brush to preserve fine mesh. Degreasing Sponge
