Dishwashing Performance Testing
Independent dishwashing performance testing for meaningful product comparisons
d-labs provides specialist performance testing for automatic and manual dishwashing products, supporting product development, competitor benchmarking, market evaluation and claims substantiation.
Testing can be designed around the product format, relevant soils, use conditions and benchmark products, with controlled test conditions, replication and technical analysis used to identify meaningful performance differences.
Dishwashing Testing Capabilities
Dishwashing performance testing designed around the product and performance question
d-labs evaluates both automatic and manual dishwashing products using test programs configured around the product format, relevant soils, use conditions, benchmark products and technical or commercial question being investigated.
Automatic dishwashing cleaning
Evaluate removal of relevant food soils and residues from dishes, glassware and other test items under controlled dishwasher conditions.
Manual dishwashing performance
Assess cleaning performance for hand dishwashing products using methods designed around grease removal, soil removal and practical consumer-relevant use.
Grease removal
Compare how effectively products remove oily and greasy soils under controlled conditions.
Rinsing & residue
Assess factors such as rinsing behaviour, residual film, spotting or other visible effects where relevant to the product and test objective.
Foam performance
Evaluate foam generation, foam stability and foam behaviour where these characteristics are important to manual dishwashing product performance or consumer perception.
Comparative benchmarking
Compare products directly against competitors, category leaders, reference products or agreed benchmarks under equivalent conditions.
The performance measures selected should reflect how the product is intended to work — and what the comparison needs to demonstrate.
Fit-For-Purpose Dishwashing Testing
Test conditions configured around the product, soil and use environment
Dishwashing performance can vary significantly depending on the product format, soil type, water conditions, temperature, dosage and cleaning process.
d-labs therefore configures each test programme around the technical or commercial question being investigated rather than applying one fixed method to every product.
Depending on the project, testing can be designed to reflect a particular market, appliance, consumer-use condition, benchmark or performance claim.
Soils & test items
Select relevant food soils, dishes, glassware or other test items to reflect the performance question being investigated.
Test conditions
Configure factors such as dosage, water hardness, temperature, contact time, dishwasher programme or manual washing conditions.
Products & benchmarks
Compare prototypes or commercial products against selected competitors, category leaders, reference products or agreed controls.
Method & replication
Select an appropriate test approach and number of replicates to generate meaningful comparative data.
The right dishwashing test is the one designed to reproduce the conditions that matter to the decision being made.
Controlled Conditions & Repeatability
Meaningful dishwashing comparisons depend on controlling the variables
Dishwashing performance can be influenced by factors beyond the formulation itself, including water hardness, temperature, dosage, soil loading, contact time, dishwasher programme and test-item preparation.
d-labs controls the relevant variables across comparative testing so products are evaluated under consistent conditions and observed differences can be interpreted with greater confidence.
Appropriate replication is also built into the test programme where required, helping reduce the influence of normal test variation and improving confidence in the conclusions drawn from the results.
Controlled test conditions
Keep relevant variables consistent across all products so the comparison remains fair and technically meaningful.
Consistent test preparation
Standardise soils, test items, dosing, equipment settings and other preparation steps that can influence the result.
Appropriate replication
Repeat testing where necessary to understand normal variation and determine whether observed differences are reproducible.
Consistency in the test method makes differences between the products easier to understand.
Benchmarking & Interpretation
Understand how dishwashing products compare — and what the differences mean
d-labs can compare automatic and manual dishwashing products against selected competitors, category leaders, reference products or agreed benchmarks under controlled conditions.
The value of benchmarking is not simply identifying which product produced the highest result. The important part is understanding where meaningful differences occur, where products are effectively comparable and what those findings mean for product development, market positioning or claims support.
Results can be analysed and presented in a clear comparative format so clients can quickly identify strengths, weaknesses and areas where further development may be worthwhile.
Competitor comparison
Compare products directly against relevant market benchmarks under equivalent test conditions.
Data analysis
Use appropriate analysis to determine whether observed performance differences are meaningful and reproducible.
Technical interpretation
Translate the results into a clear conclusion that supports development, benchmarking, claims or commercial decision-making.
Good testing should explain not only which product performed better, but whether the difference is meaningful and why it matters.
