    S04 E16 - Mike Valenti - Why Most Cleaning Failures Aren’t Chemistry: Equipment, Throughput & Process Control

    When parts aren’t coming out clean, the first instinct is to change the chemistry. In many cases, that’s not where the problem starts. In this episode of Seen & Solved, Tim Pennington talks with Mike Valenti about what actually drives cleaning performance in a metal finishing operation. It’s a practical look at a common issue across shops – trying to solve systemic problems with chemistry, when the limitation is really equipment, capacity, or how the process is being run. Mike walks through why most cleaning challenges trace back to equipment, not the cleaner itself, and how factors like throughput, part geometry, and soil loading determine whether a system will hold or break down. From immersion and spray systems to ultrasonics, the conversation covers where each approach works and where it doesn’t. They also get into what you can see on the floor when things aren’t right: rinse stages that can’t keep up, oil carrying through the line, tanks being changed too frequently, or systems that were sized for a different level of production. As more operations move from solvent to aqueous cleaning, those gaps become harder to ignore, especially with complex parts and tighter performance requirements. The takeaway is straightforward. Cleaning isn’t a single variable, it’s a system. Spray pressure, coverage, time, temperature, rinsing, and oil removal all have to work together. If the equipment isn’t set up or maintained to support that, no chemistry change will stabilize the process.

    S04 E15 - David Govoni - Choosing the Right Aqueous Cleaner - The Chemistry Behind Clean

    Choosing the right aqueous cleaner isn’t always straightforward. Metal type, soil load, equipment, temperature, and wastewater considerations all influence performance—and small missteps in cleaning can lead to bigger problems downstream. In this episode of Seen and Solved, Dave Govoni, Senior Chemist at Hubbard-Hall, shares practical insight from years of hands-on experience in metal finishing. He walks through how to approach cleaner selection based on real-world conditions, from degreasing and oxide removal to managing sensitive metals like aluminum, copper, and brass. The conversation covers how pH and temperature impact cleaning performance, why rinsing and bath monitoring are often overlooked, and how surfactants, emulsifiers, and inhibitors work together to deliver consistent results. Dave also highlights common causes of staining, residue, and adhesion failures—and what to look for on the line before those issues show up later in the process. There’s also a practical discussion on extending bath life, stabilizing performance, and reducing waste treatment impact through better process control and operator awareness. If you work in metal finishing, surface preparation, powder coating, plating, or industrial manufacturing, this episode offers straightforward guidance you can apply directly to your process.

    S04 E14 - Jason Potts - Breaking Through Paraffin: Removing Wax-Based Oils from Metal

    Paraffin-based rust preventatives are some of the most stubborn soils in metal finishing. When they’re not removed properly, shops pay the price — in labor, solvent cost, safety concerns, and poor adhesion. In this episode of Seen and Solved, a finishing facility was forced to wipe every single part with acetone before cleaning just to remove a tenacious paraffin-based oil. The manual step slowed throughput, increased chemical spend, and exposed employees to unnecessary solvent fumes. Instead of accepting the process as “the way it’s always been done,” Hubbard-Hall Technical Representative Jason Potts investigated the root cause — identifying the oil as paraffin-based and reformulating the cleaning stage using AquaEase® PL 918, a high-performance alkaline cleaner designed to remove heavy oils at lower operating temperatures. Within one week: • Acetone wiping was eliminated • Labor and solvent costs were reduced • Line throughput improved • Adhesion risks were minimized • Workplace safety improved If you’re dealing with: • Paraffin-based rust preventatives • Adhesion failures in plating or coating • Excessive manual cleaning steps • High-temperature alkaline cleaning limits (160°F max systems) • Slow production throughput in finishing lines This episode walks through how to identify the chemistry challenge and correct it without adding complexity. Serving metal finishers, electroplaters, powder coaters, and manufacturers across the U.S., Hubbard-Hall helps facilities improve cleaning performance, surface preparation, and overall finishing efficiency.

    S04 E13 - Travis Hilton - Getting Proper Ratios on Tin/Lead Deposits

    In this episode of Seen and Solved, Travis Hilton, Operations Manager at Hubbard-Hall, discusses one of the most critical controls in electronics and specialty metal finishing: achieving and maintaining the proper tin-lead plating ratio. Tin-lead electroplating is still widely used in aerospace, medical, military, and electronics applications where solderability, ductility, and corrosion resistance are required. Maintaining consistent alloy ratios—such as 60/40 or 90/10 tin-lead—depends on tight control of bath chemistry, current density, temperature, agitation, and preventative maintenance. This episode covers:- How modern methane sulfonic acid (MSA) tin-leadplating baths are formulated- How tin and lead concentrations are measuredusing titration and atomic absorption (AA)- Why deposit ratios can shift even when solutionchemistry is in control- How current density influences alloy compositionand coating performance- The effect of tin-rich vs. lead-rich deposits onsolderability, ductility, and brittleness- Common issues such as stannic tin formation,organic contamination, and bath instability- Filtration, anode maintenance, and processcontrols to extend bath life- Waste treatment and disposal considerations forlead-bearing plating chemistries For plating engineers, process managers, and quality teams working with tin-lead electroplating for electronic components, connectors, and wire bonding, this discussion explains how chemistry control and operating discipline directly impact deposit ratio, reliability, and long-term performance.

    S04 E12 - Robin Deal - Wastewater Treatment Essentials for Today’s Finisher

    Wastewater compliance can feel overwhelming for metal finishers, but it doesn’t have to be. In this episode of Seen & Solved, the conversation focuses on what wastewater inspections really involve, what regulators are looking for, and how facilities can stay prepared year-round. The discussion covers how inspections are conducted, common issues that lead to notices of violation, and why housekeeping, labeling, and recordkeeping play a critical role in maintaining compliance. The episode also explores how system maintenance impacts performance, including tank cleanliness, sludge buildup, and dwell time, as well as how improper conditions can affect discharge results. Listeners will gain insight into how regulators approach fines and follow-up, what’s expected when corrective action is required, and how wastewater treatment systems are properly sized based on real operational demands. Additional topics include operator licensing requirements, how they vary by state, and why ongoing education is essential as regulations and technologies continue to evolve. Emerging trends such as PFAS, advances in treatment methods, and the balance between regulatory expectations and economic feasibility are also addressed.

    S04 E11 - Gary Raihl - Pretreatment Made Simple: A Step-by-Step Approach to Better Finishes

    Pretreatment isn’t guesswork—it’s a discipline built on decisions made long before parts reach the finish line. In this episode of Seen & Solved, Gary Raihl, Business Development Manager at Hubbard-Hall, shares how pretreatment systems should be evaluated from the ground up—looking beyond individual products to the full process. Drawing on decades of experience in powder coating and chemical processing, Gary explains why equipment design, chemistry selection, and operator ownership must all work together to deliver consistent results. This episode covers: • Assessing existing pretreatment systems based on stage count, process flow, and equipment condition • Why tank materials, heat placement, and system design matter more than most realize • Setting realistic performance goals and approval requirements before changes are made • Balancing time, temperature, and concentration when real-world constraints exist • Avoiding common mistakes that shorten equipment life and create downstream issues • Training operators and using process control logs to maintain consistency and accountability • Validating performance through testing and documentation—not assumptions • The communication gaps between equipment, chemistry, and finishing partners that lead to the most expensive failures Whether you’re bringing a new line online or working to improve control on an existing process, this episode takes a practical look at pretreatment as a system—not a single product choice—and what it takes to build a process that holds up in daily production.
