About CarCareTruth
CarCareTruth is an independent car-care product scoring database. Every product we list is graded on three axes — effectiveness, ingredient health impact, and environmental footprint — with the rubric and underlying data published openly on each product page.
Why we exist
Most car-care reviews answer one question: does it work? They skip a second question that matters just as much: is it safe?
Modern car-care products contain serious chemistry — strong acids in wheel cleaners, silicone solvents in tire dressings, glycol ethers in maintenance fluids and interior cleaners. Some carry California Prop 65 warnings. Some are aquatic toxins. Many are sold without a word about what's in the bottle or what runs into your driveway.
We translate the Safety Data Sheet into plain English so the chemistry stops being a footnote.
How we score
Every product page shows the math. Base score, deductions, bonuses, and which Safety Data Sheet section each input came from. The rubric is category-specific and published per category.
- Quality (effectiveness) — how well it actually does the job, sourced from community results, manufacturer claims with citations, and third-party testing where available.
- Health impact — translated directly from the Safety Data Sheet. GHS hazard codes, signal word, PPE tier, and ingredient-level concerns where the SDS discloses them.
- Environmental impact — aquatic toxicity, VOC content, drain-destined exposure pathway.
What makes us different
- H-codes by number. We cite the actual GHS hazard codes (H318, H334, H335, etc.) on every product, with plain-English translations. Competitors don't publish this.
- Defamation-safe. We never make negative claims about a named product. Educational chemistry stays at the class level; specific-product mentions are pure SDS-receipt facts.
- Independent of brands. No brand pays for placement. Scoring happens before affiliate availability is even considered.
- Broad scope. Detailing, maintenance, accessories, EV care, mods, off-road gear, dashcams — the whole car-care umbrella, not just paint correction.
Editorial standards
Every product page includes its SDS link, its scoring rubric reference, and the chemistry breakdown. We translate regulatory data; we do not make health or safety recommendations. The Brent test for every claim: can a non-technical owner verify it from the product's own SDS without taking our word for it?
