Modified alcohols as a future-proof, sustainable and compliant cleaning solution

Modified alcohols can be a long-term solution for effective solvent cleaning. They are free from PFAS, PERC, or other halogenated solvents. Cleaning with modified alcohols in closed cleaning systems can fulfill challenging technical requirements. The process is cost effective, meets regulatory requirements, and is sustainable. Michael will compare modified alcohol cleaning with aqueous cleaning and will discuss unique advantages of the modified alcohol solvents.


PFAS, the Recent 3M Announcement & Options for Critical Cleaning

Just in time for the holidays, 3M dropped a bomb in the critical cleaning industry by announcing that Novec solvents will be discontinued by the end of 2025. Customers who have already been dealing with unreliable deliveries of Novec solvents, now have to decide how to process this news and formulate a plan to keep their operation going. Paul Blair and Kevin Pawlowski with Techspray have over 40-years combined experience managing these types of transitions, including HCFC-141b and AK225. Techspray has immediate solutions to replace Novec solvents that can avoid the lengthy qualification process, and keep your critical cleaning process running without delay.


Wastewater Management for Aqueous Cleaning Processes with Evoqua Water Technologies
Aqueous cleaning operations use a wide variety of chemistries in several different process types. One thing they all have in common is that they generate wastewaters that must be handled appropriately and compliantly. One size does not fit all; just as cleaning wastewater composition varies from application to application, wastewater treatment options also vary depending on the contaminants as well as local requirements - and desires - for disposition of the treated wastewater. This webinar will discuss the totality of wastewater management, touching on not only appropriate cleaning wastewater treatment technologies but also the importance of wastewater characterization in identifying the correct treatment process for each application as well as considerations for post-treatment disposition of residuals.


Cleaning Tight Features and Small Lumen Tubing with Vacuum Cycle Nucleation (VCN)

Vacuum Cycle Nucleation is an immersion process that can use either aqueous or solvent cleaning chemistry. The basis of the process is to modulate the vacuum pressure in the processing chamber above and below the vapor pressure of the cleaning fluid causing vapor bubble to form and escape from within tight features. Join us to learn about this unique cleaning technique.


Post-machining Cleaning - an accelerated guide to nonionic surfactant chemistry in cleaning formulations

With the hundreds of available surfactants on the market to incorporate into a metal cleaning formulation, the task of picking the correct surfactant can be daunting. Understanding the chemistry of nonionic surfactants is vital for optimum performance.
In this webinar, the PQCW Team (Barbara and Ed Kanegsberg and Darren Williams) will interview Stephanie Cole of Clariant Corporation.
Stephanie will discuss how the backbone of nonionic surfactant chemistry can be altered in many directions to achieve ideal cleaning performance. Related test methods and starting formulations will also be discussed.

Overcome cleaning problems for critical applications - Compare modified alcohol, hydrocarbons, chlorinated solvents, and water

For many high precision industries such as aerospace, automotive or medical technology, parts cleaning – if not done properly – can have a detrimental impact on the manufacturing process. Insufficiently cleaned parts can affect many subsequent steps such as coating, welding, bonding, assembling and heat treatment. The choice of the right cleaning chemistry holds the key to an effective cleaning process – but how do you make the right decision?

Join the PQCW Team and SAFECHEM's Michael Onken as we will look at the key factors determining cleaning effectiveness. We will clarify the differences and unique strengths between chlorinated solvents, modified alcohols, hydrocarbons, and aqueous cleaning to help you assess their suitability for your process. Importantly, we will explain how closed cleaning equipment enables you to achieve greater cost efficiency while meeting the highest safety standards and sustainability goals.
In this webinar, you will learn about:
• What really matters in determining cleaning effectiveness
• Benefits and applications of different cleaning media
• Key considerations when assessing the suitability of a cleaning chemistry

Mike Valenti of Hubbard Hall informed us on how to overcome the Challenges of Aluminum Cleaning. This was a VERY informative webinar.

Cleaning aluminum is far different and more challenging (one might say more aggravating!) than cleaning stainless steel. Metal finishers worry about over-etching, difficult stains and damaging expensive aluminum. This webinar will cover the basic principles that make aluminum unique, cleaners that remove stubborn contaminants and case studies on how to reduce the cost, complexity, and chemical consumption of cleaning aluminum.

Special considerations when cleaning aluminum:

  • How is the aluminum being used? Will a caustic soda based cleaner impact this?
  • What’s the contaminant you are trying to remove?
  • Is over-etched aluminum a concern?
  • Have you thought about post-cleaning waste treatment?


Many difficult and adherent residues require mechanical action and/or high emulsifying detergents. These are largely not feasible in automated washers, high-pressure, spray-in-air units and similar clean-in-place (CIP) systems. At these times, cleaning out of place (COP) is necessary. This may be manual cleaning like scrubbing or soaking, or use of an ultrasonic cleaner. Sign up to view our webinar (from Sep 14th) by Michael Moussourakis of Alconox Inc. who will highlight when COP cleaning is needed, cleaning qualifications and verification, and review of case studies.

Reduce Downtime, Cut Costs in Aqueous Surface Prep Lines

Metal finishers rely on aqueous emulsifying cleaners for effective surface prep in operations like plating, anodizing, and galvanizing. The “pinch point” is the downtime and costs associated with changing out and disposing of the baths. Mike Valenti of Hubbard Hall explains how a combination of an effective emulsifying cleaning agent with new, efficient filtration can dramatically reduce process downtime, cut the cost of cleaning chemistry (reclaim 95% of cleaning agent!), reduce waste and energy costs, and improve product quality.
