Residue is the enemy of a properly-functioning product. Manufacturers demand a “perfectly clean” surface. We are experts in critical cleaning – but critical cleaning is not the same as achieving zero residue. Rather than aiming at a perfectly clean surface, aim for the right cleanliness relative to subsequent storage, assembly and/or coating processes and to the performance requirements of the final product. A perfectly clean surface is unrealistic; and it may be undesirable. Rust preventative, for example, is a purposeful, desirable residue.

Inadvertent residue
Soil may be deposited on product surfaces inadvertently. For example, particles or oil mists from a neighboring facility can waft through air ducts and deposit on surfaces. Handling product without wearing gloves or gowns causes fingerprints and skin flakes to deposit. With careful engineering controls and employee practices, it is possible to minimize these inadvertent contaminations.

PQCW – Practical, Quality Manufacturing

What you and your company need to stay in the lead. The next Product Quality Cleaning Workshop is set for May 13 – 14, 2020 at Sam Houston State University, Huntsville, TX.

Take Steps to Make Cleaning Changes

A well-designed and carefully maintained cleaning process is essential to build and assemble quality product and to expand the customer base. Making rash decisions can disrupt manufacturing production and even result in shutdowns. In the May issue of Production Machining, we discuss how avoiding the decision to choose a new process also has risks.  Consider the risks of indecision, including the impact on profits and on customer satisfaction.
