The science of cleaning — why products work, which surfaces need what, and how to clean with chemistry instead of guesswork.
Building our libraryEvery cleaning product is a chemistry delivery system. Surfactants form micelles around grease. Acids donate protons to dissolve mineral deposits. Oxidisers break chromophore bonds to remove stains. Enzymes catalyse the breakdown of specific organic molecules. Understanding these mechanisms means you stop buying products by marketing claim and start choosing by chemical function.
Cleange explains the science behind every cleaning method — what works, what doesn't, and why. Every article is cited from peer-reviewed research in surface chemistry, material science, and microbiology.
Acetic acid donates protons to calcium carbonate, producing water-soluble calcium acetate, CO₂ gas, and water. The limescale dissolves because the reaction products are all soluble. Cleaning vinegar (6%) works roughly twice as fast as culinary vinegar (4–5%).
Surfactant molecules have a hydrophilic head and hydrophobic tail. The tails embed into grease, the heads face water, forming micelles — tiny spheres with grease trapped inside and water-compatible surfaces outside. The grease suspends in water and rinses away.
Sodium hypochlorite reacts with acetic acid to produce chlorine gas (Cl₂), which is toxic at concentrations as low as 1 ppm. This applies to bleach mixed with any acid, including citric acid and some toilet cleaners.
Depends on the soil. Hot water helps surfactants emulsify fats. For protein stains (blood, egg), hot water is worse — it denatures and sets the protein. Warm water (40–50°C) is the optimal general-purpose compromise.
Three mechanisms: mild alkalinity (pH 8.3) saponifies light grease; crystal structure provides gentle abrasion; combined with acid, CO₂ effervescence lifts debris from crevices. Abrasion is the primary mechanism.
Cleange is part of a multi-domain science network. The chemistry of cleaning overlaps with cooking science — grease removal is fat chemistry, stain setting is protein denaturation, limescale is the same calcium chemistry that affects water hardness in cooking.
