Seventh Generation Disinfecting Multi-Surface Review
Quick Take
Overall Score: 8.0/10
Seventh Generation's disinfecting cleaner solves a real problem: most non-toxic cleaners don't actually kill germs. Using thymol derived from thyme oil, this product is EPA-registered to kill 99.99% of household germs while avoiding synthetic chemicals. The trade-off is a lower safety rating (EWG-C) compared to their Free & Clear non-disinfecting products.
The Verdict: The best widely-available botanical disinfectant for families who need germ-killing without resorting to bleach or quats. The thymol-based formula is meaningfully safer than conventional disinfectants while delivering verified efficacy. Accept the EWG-C rating as the cost of actual disinfection.
