Using Thinner in a SafteeKleen Wash Out Tank: A Practical Guide

In the screen printing industry, maintaining clean screens is crucial for ensuring high-quality prints. One commonly used piece of equipment for this purpose is the SafteeKleen wash out tank. However, the associated costs of maintaining and replenishing the cleaning fluids can be prohibitive, especially for small businesses or those who infrequently clean screens. This guide provides a comprehensive overview of alternative solutions to using proprietary SafteeKleen services and fluids, focusing on cost-effective and efficient methods.

Understanding the Wash Out Tank

The SafteeKleen wash out tank is a robust cleaning system designed to handle various industrial cleaning tasks, including the cleaning of embroidery screens. Over time, the cleaning fluid in the tank can become contaminated with ink residues and other particulates, necessitating its replacement.

Alternatives to Proprietary Cleaning Fluids

For businesses looking to avoid the expense of a service contract with SafteeKleen, there are several viable alternatives:

1. Mineral Spirits: Mineral spirits are a cost-effective substitute for proprietary SafteeKleen fluids. Available at hardware stores like Home Depot, they can effectively clean screens without the high costs associated with service contracts. Typically, about five gallons of mineral spirits are sufficient for replenishing a wash out tank.
2. Citrus-Based Ink Cleaners: Citrus-based cleaners are another excellent alternative. They are effective in removing ink and ghost images from screens and are generally preferred for their environmental benefits and lower toxicity. These cleaners can be found through various suppliers, including ICC Chemical, which provides direct sales and knowledgeable regional representatives.

Proper Disposal of Used Solvents

Disposing of used cleaning solvents responsibly is essential. Mineral spirits and other cleaning agents can be harmful to the environment if not handled correctly. Therefore, it's crucial to collect the used solvent in a suitable container and find a local recycling facility that can process it.

Health and Safety Considerations

When choosing cleaning solvents, it is important to consider health and safety. For instance, paint thinner, while effective, can strip paint off surfaces and pose serious health risks, including potential carcinogenic effects. In contrast, mineral spirits are nonflammable and generally safer for regular use. Nevertheless, always ensure adequate ventilation when using any solvent to mitigate inhalation risks.

Recommendations from Industry Practitioners

Many professionals in the screen printing industry have shared their experiences and preferences regarding cleaning solutions. For example, the Franmar "color change on press" brand is highly recommended for its effectiveness in cleaning screens and handling ink changes efficiently. Additionally, ICC Chemical products are favored for their specialized formulations designed specifically for screen printing applications.

Practical Tips

• Cleaning Frequency: For businesses that clean screens infrequently, it might be more economical to use off-the-shelf mineral spirits or citrus-based cleaners rather than engaging in a service contract.
• Evaluating Solvents: If trialing a service like SafteeKleen, ensure the solvent provided is appropriate for your specific cleaning needs. Different solvents are available, and the wrong choice can lead to inefficiencies and potential health hazards.
• Regional Suppliers: Look for regional suppliers of recommended products to reduce shipping costs and ensure timely deliveries. ICC Chemical, for instance, has a southeast regional representative and ships directly from Cincinnati.

Conclusion

Maintaining a clean and efficient screen printing operation does not necessarily require expensive service contracts. By using cost-effective alternatives like mineral spirits and citrus-based cleaners, businesses can achieve high-quality cleaning results while managing costs effectively. Always prioritize proper disposal methods and consider health and safety when selecting cleaning solvents.
