Low foam: a sign of cleaning problems
While professional low-foam detergents do not produce as much foam as domestic ones, a marked drop points to a problem. Lack of foam usually correlates with poor cleaning performance and leads to user complaints.
Impacts
- Laundry that does not come out properly clean
- Stains left behind
- Dissatisfied users filing complaints
- Perception that the detergent is poor quality
- Wasted product if the root cause is hard water
- Hidden cost of rewashing
Causes
Detergent under-dosing
The system delivers less product than required. The most common cause.
Very hard water
Water high in limescale "consumes" part of the detergent, reducing foam and cleaning power.
Degraded or expired detergent
Detergents lose effectiveness over time. Product stored too long will not foam correctly.
Dosing system faults
Out-of-calibration pumps, blocked tubes or empty drums prevent correct dosing.
Incorrect water temperature
Some detergents need a minimum temperature to activate fully.
Solutions
Check and recalibrate dosing
Use a measuring cylinder to verify the actual volume delivered. Adjust the pumps if the quantity is below the recommended level.
Use Biogold for better performance
Concentrated enzymatic detergent effective from 20 °C.
Inspect the dosing system
Check tubes, connections and pumps. Clear any blockages and check the drums.
Use Power Gold for heavily soiled loads
High-performance detergent that retains efficacy in demanding conditions.
Manage stock rotation
Ensure products are used before their expiry date. FIFO method.

Preventive protocol
- Request a water-hardness report from the supplier twice a year
- Use a measuring cylinder on the 1st of every month to verify each pump's actual dose
- Include visual inspection of tubes and connections in the maintenance routine
- Apply FIFO and mark the delivery date on every new drum
- Calculate real monthly consumption to keep only 1–2 months of rolling stock
- Evaluate the ROI of a water softener if hardness exceeds 25 °fH
