Things to know first

# Dos

• Read instructions: Always read the manufacturer’s instructions before using any chemical cleaners or solvents, and follow all safety guidelines. Ensure you’re in a well-ventilated area when cleaning.
• Use non-corrosive detergents: Clean with non-corrosive detergents to prevent photo emulsion from corroding and peeling off.
• Small area testing: Before cleaning the entire screen, test the cleaning agent on a small area to ensure it does not damage the mesh or emulsion.
• Prompt drying: Dry the screen as soon as possible after cleaning to prevent rusting. Use compressed air or allow it to air dry in a dry, well-ventilated area.
• Dry environment: Keep the screen clear of damp environments to avoid rust.

# Don'ts

• Avoid sharp tools: Do not use hard or sharp tools to scrape off the ink, as this can damage the screen.
• Avoid excessive force: Be gentle during cleaning to prevent damage to the screen, especially on areas with photo emulsion.

How to do it

# For water-based ink

Water-based inks are relatively easy to clean, often requiring only water and a bit of manual effort.

1. Rinse with Water: Begin by rinsing the screen under running water. Use a gentle stream to avoid damaging the mesh.
2. Soft Brush: If there are stubborn ink residues, use a soft brush to gently scrub the screen. Avoid using abrasive materials that could damage the mesh.
3. Soak Overnight: If the ink has dried and become difficult to remove, soak the screen in water overnight. This will help to soften the ink, making it easier to clean.
4. Non-Corrosive Detergents: For a more thorough cleaning, you can use non-corrosive detergents. Apply the detergent and gently scrub with a soft brush.
5. Rinse and Dry: After cleaning, rinse the screen thoroughly with water to remove any detergent residues. Allow the screen to air dry or use compressed air to speed up the drying process.

# For oil-based ink

Oil-based inks are more challenging to remove and often require the use of solvents.

1. Solvent Application: Use a solvent such as acetone to dissolve the ink. Apply the solvent to the screen using a soft cloth or brush.
2. Ventilation: Always clean oil-based inks in a well-ventilated area. Solvents can release harmful fumes, so it’s important to work in a space with good airflow and avoid any open flames.
3. Soft Brush: Gently scrub the screen with a soft brush to remove ink residues.
4. Rinse and Dry: Rinse the screen thoroughly with water to remove any remaining solvent. Allow the screen to air dry or use compressed air to ensure it is completely dry.
