About Cleange

What This Is

Cleange is a suite of client-side tools that answer one question:is it safe to mix these two cleaning products?

• Mix Checker — select two products, get an instant Safe / Caution / Danger verdict with the underlying chemistry
• Unmixable Finder — select one product, see every product in our database that's dangerous to combine with it

How the Scoring Works

Each product in our database is classified by its active chemical ingredients — hypochlorite, ammonia, acid, peroxide, solvent, and other reactive classes. When you check two products, the engine tests every chemical class in Product A against every class in Product B, checking 30 interaction rules.

The most severe match determines the verdict. If any combination produces a toxic gas, corrosive compound, or violent reaction, the result is Danger. If the interaction is mild or reduces effectiveness, the result is Caution. If no known harmful interaction exists, the result is Safe. The engine errs on the side of caution — a false warning is safer than a missed danger.

Where the Data Comes From

Chemical interaction rules and product classifications are compiled from published safety and toxicology sources:

• CDC — Morbidity and Mortality Weekly Report on cleaning chemical exposures
• EPA — CAMEO Chemicals reactivity database for chemical compatibility
• AAPCC — National Poison Data System annual reports (exposure frequencies and outcomes)
• Published toxicology — Chemistry World, Toxicology Education Foundation, university chemistry departments
• Manufacturer SDS — Safety Data Sheets for active ingredient identification

Products are classified by chemical class, not exact formulation. A product labeled as "bleach cleaner" is classified under hypochlorite regardless of brand. This approach is conservative — it may flag a product with a very low concentration as dangerous when the practical risk is lower.

What We Are Not

Cleange is not medical advice. It is not a substitute for reading product labels. It is not Poison Control. If you or someone you know has been exposed to a chemical mixture, call Poison Control at1-800-222-1222 (24/7, free, confidential) or call 911 for breathing emergencies.

How We Make Money

Display advertising. Ads are served by Google AdSense alongside the tools. Cleange has no financial relationship with any cleaning product manufacturer, chemical company, or retailer. The tools have no incentive to flag products as safe or dangerous — the chemistry determines the verdict.

Privacy

Every safety check runs in JavaScript on your device. No product selections are transmitted. No results are stored. No account is needed. No cookies are set by Cleange (third-party ad cookies are documented in ourprivacy policy). Close the tab and your data is gone.

Corrections

If you notice incorrect data — wrong chemical classification, missing product, outdated formulation, or an incorrect interaction rule — let us know. We update data periodically and prioritize corrections with cited sources. Include the product name, the issue, and a reference if possible.

Limitations

These tools classify products by chemical class, not exact formulation or concentration. A product with trace amounts of a reactive ingredient may receive the same verdict as one with a high concentration. Product formulations change over time — a product's classification is based on the formulation at the time of data entry. Always read the product label and follow manufacturer instructions.
