Disclaimer

CarCareTruth.com publishes editorial reviews of consumer auto-care products. The site is operated by SierraNova Labs LLC.

Editorial nature

Our reviews are opinion combined with public information: product label text, manufacturer claims, Safety Data Sheets, regulatory databases (Prop 65, EPA, CARB), peer-reviewed literature, and user reports. Effectiveness scores reflect editorial judgement about real-world performance. Health-impact scores reflect editorial judgement about what regulators have flagged and how the product is typically used.

Not professional advice

Nothing on CarCareTruth.com is medical, legal, automotive, or regulatory advice. We are not chemists, toxicologists, mechanics, or attorneys. If a product makes contact with your skin or your health, consult a doctor; if it might void a vehicle warranty, consult the manufacturer; if you have a regulatory question, consult an actual regulator.

Read the label

Always follow the manufacturer's label directions and Safety Data Sheet. Use personal protective equipment as recommended. Do not mix cleaning chemicals. Some products that are safe in isolation are dangerous when combined (notably acidic wheel cleaners and bleach-based all-purpose cleaners).

No warranty

The site is provided "as is" with no warranty of accuracy, completeness, or fitness for any purpose. Product formulations and labels change over time; a review accurate today may be out of date in 12 months. Ratings, ingredient lists, and Prop 65 statuses on this site are best-effort and not a substitute for the actual current label on the bottle in your hand.

Trademarks & fair use

Brand names, product names, and product images are the property of their respective owners. Their use on CarCareTruth.com is for editorial / nominative-fair-use purposes only. We are not endorsed by, affiliated with, or sponsored by the brands we review (except where a specific page is clearly marked as Sponsored).

User-generated content

Reviews and comments posted by users are the views of those users. They do not represent the views of SierraNova Labs LLC. We moderate for spam, abuse, and obvious falsity, but we do not pre-screen every post.

Affiliate disclosure

We earn affiliate commissions on outbound retailer links — full disclosure on the /disclosure page. Commissions never influence ratings.
