Troubleshooting chemical Dispensing Issues in Automatic and Touchless Car Washes
Nothing disappoints a car wash customer faster than a car that comes out looking less than spotless. If you’re hearing complaints about poor cleaning or noticing visible residue left behind, your delivery system is likely the source of the problem. For car wash operators, quickly identifying and resolving chemical dispensing issues is critical for maintaining your reputation—and your bottom line.
Why Proper Chemical Dispensing Matters
The right chemistry, delivered at the right concentration, is essential for breaking down dirt, road film, and grime. If your system isn’t dispensing your products properly, you’ll see inconsistent cleaning results, increased customer complaints, and potential equipment strain as the system tries to compensate. High-performance chemistries—like the proprietary, USA-made formulas from Blair Ceramics—can only deliver their full benefits when your equipment is running smoothly.
Common Causes of Soap Dispensing Problems
Clogged Injectors
Over time, chemical injectors can become blocked by mineral deposits, undissolved solids, or buildup. This restricts flow and leads to uneven or inadequate soap application.
Incorrect Dilution Ratios
If your system isn’t calibrated correctly, you might be using too much or too little chemical. Both extremes can cause problems: too little means poor cleaning, while too much can leave sticky residue and waste product.
Empty or Low Chemical Tanks
It sounds simple, but empty tanks or tanks running low on product are a frequent culprit. Automated systems may not always provide clear alerts, leading to unnoticed outages.
Quick Fixes and Preventive Measures
Flush the Lines
Regularly flushing your chemical lines prevents buildup and keeps everything flowing smoothly. Make it part of your routine maintenance, especially if you switch products or chemistries.
Verify Chemical Levels
Check your soap tanks daily. Top off as needed and ensure lids are sealed to prevent contamination or evaporation.
Recalibrate Your Dispensing System
Periodically check and adjust your dilution settings. Use manufacturer guidelines and test the output to ensure you’re delivering the optimal amount of product for each wash cycle.
Use High-Quality, USA-Made Chemistries
Low-grade products can clog injectors and leave residue. Blair Ceramics’ in-house chemistries are designed for maximum performance and minimal equipment hassle—giving you better results and fewer headaches.
