Knowledge Centre
Plain-language articles that explain cleaning, formulation, surface science, and performance testing for technical and nontechnical teams.
Explore the Knowledge CentreTandell Academy
Practical cleaning science, clearly explained.
Independent education for the people who develop, test, position, sell, and use cleaning products—without assuming a background in surface chemistry.
Understand why a product behaves the way it does, what a measurement really means, and where testing is still required.
Two levels of learning
Start with the answer. Go deeper when you need to apply it.
The Academy separates free public explanations from structured learning. The Knowledge Centre answers the practical question; future courses will add demonstrations, worked examples, exercises, and assessments.
Academy Courses
Deeper self-paced modules with demonstrations, practical scenarios, exercises, knowledge checks, and certificates of completion.
Stay informed
The first planned course is Cleaning Fundamentals and Sinner's Circle.
Featured explanation
Dilution, dosing and at-use concentration
The product in the bottle is not always the product that reaches the soil.

What Are You Actually Testing?
Learn why dilution ratio, dose, product concentration, active concentration, and application loading answer different questions in a cleaning-product comparison.

Built around the questions product teams actually ask.
Cleaning Fundamentals
Sinner's Circle, dilution, dosing, dwell time, temperature, and mechanical action.
Surfactant Science
Surfactants, micelles, critical micelle concentration, and soil removal.
Surface Science
Surface tension, contact angle, wetting, interfacial tension, and surface energy.
Formulation Fundamentals
pH, water hardness, chelation, solvents, and ingredient concentration.
Foam and Appearance
Foam behaviour, rinsing, residue, spotting, filming, and visible product cues.
Testing and Claims
Controls, repeatability, meaningful differences, and defensible interpretation.
