Many manufacturers continue using the same washer chemistry year after year because “it’s working.” But what many don’t realize is that a chemical program can slowly become less effective as production changes, new contaminants are introduced, equipment ages, and operating costs increase.

The question isn’t simply whether your washer is cleaning parts. The better question is:

Is your current chemistry helping your operation perform at its highest level?

Here are several signs it may be time to evaluate a change.

1. Cleaning Performance Has Become Inconsistent

If operators are seeing occasional cleaning failures, spotting, residue, or inconsistent coating adhesion, the chemistry may no longer be optimized for the soils entering the system.

Manufacturing processes evolve over time. New lubricants, coolants, machining oils, or production materials can overwhelm a chemical program that once performed well.

A chemistry review can often restore consistent cleaning without major equipment modifications.

2. Chemical Consumption Continues to Increase

Are you adding more chemistry than you did a year ago?

Excessive chemical usage can indicate:

• Poor bath stability
• Contamination buildup
• Inefficient formulations
• Incorrect concentration targets
• Chemistry that no longer matches production demands

Lower chemical consumption often translates directly into lower operating costs.

3. Energy Costs Are Rising

Your washer chemistry directly affects energy consumption.

If chemicals require higher operating temperatures or longer wash cycles to achieve acceptable cleaning, you’re paying more in fuel, electricity, and production time.

Modern formulations are often designed to clean effectively at lower temperatures, helping reduce overall utility costs while maintaining performance.

4. Maintenance Is Becoming More Frequent

If your maintenance team is regularly dealing with sludge buildup, clogged nozzles, excessive foam, or dirty tanks, your chemistry may be contributing to the problem.

The right chemical program can help:

• Reduce residue buildup
• Improve bath life
• Keep equipment cleaner
• Reduce unscheduled downtime
• Extend equipment life

Less maintenance means more production time.

5. Water Treatment Costs Keep Climbing

Your chemical program doesn’t just affect the washer—it also impacts wastewater treatment.

Chemistry that is easier to separate, treat, or recycle can reduce wastewater costs and improve environmental performance.

6. Production Has Changed

Many facilities have added new product lines, increased throughput, or changed manufacturing processes without ever revisiting their washer chemistry.

What worked five years ago may not be the best solution today.

Periodic chemical evaluations help ensure your cleaning process keeps pace with operational changes.

7. Your Supplier Only Delivers Chemicals

A chemical supplier should provide more than products.

The best chemical management partners routinely evaluate:

• Washer performance
• Chemical concentrations
• Operating costs
• Energy usage
• Equipment condition
• Process efficiency

Their goal should be continuous improvement—not simply replenishing drums.

The Bottom Line

Changing your washer chemistry isn’t about changing chemicals for the sake of change. It’s about improving the entire process.

The right chemistry can help reduce operating costs, improve cleaning consistency, extend equipment life, minimize downtime, lower energy consumption, and support higher-quality finished products.

If your washer process hasn’t been evaluated in several years, a chemical assessment may uncover opportunities for improvement that deliver measurable savings without requiring a major capital investment.
