This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
The single highest-value page here is the mixing matrix — bleach with acid gives chlorine, bleach with ammonia gives chloramine, bleach with alcohol gives chloroform, peroxide with vinegar gives peracetic acid — as a grid of every common household pair with the gas, the symptoms and the poison-centre number per country.
Around it, one page per product class (chlorine bleach, oxygen bleach, ammonia, acids for limescale, drain openers, oven cleaner, disinfectant sprays, quats, alcohol gels, "eco" surfactants), each with what the CLP pictograms on the bottle mean, whether the claim is even permitted under the EU biocides rules, and where plain detergent does the same job.
How to use it
Use Cleaning products: what not to mix, and what to buy to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

| Finnish | mitä pesuaineita ei saa sekoittaa keskenään |
| Russian | что нельзя смешивать хлорку и уксус |
| English | bleach and vinegar chlorine gas |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: CDC/NIOSH chemical hazard pages (public domain), EU CLP Regulation 1272/2008 pictogram set and Biocidal Products Regulation 528/2012 (open), national poison-centre numbers (public). · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
Scope and boundaries
