Clorox Faces Class Action Over Recalled Mistolin and Lestoil Cleaners

Consumers in Puerto Rico have filed a federal class action accusing The Clorox Company of selling scented Mistolin and Lestoil cleaners that may contain a bacterium linked to serious infections.

The case, Toro v. The Clorox Co., Case No. 4:26-cv-10893, is pending in the U.S. District Court for the Northern District of California. Court coverage also reports a separate proposed class action from a Puerto Rico resident that raises similar claims.

The lawsuits follow a recall announced on September 3, 2026 with the U.S. Consumer Product Safety Commission. The recall covers about 6.3 million bottles of scented Mistolin dilutable cleaners and Lestoil heavy duty multi-purpose cleaners sold in Puerto Rico and the U.S. Virgin Islands.

Which Mistolin and Lestoil Products Are Recalled?

Retailers included Walmart, Sam's Club and Costco, and prices ran from $1.40 to $8. Affected bottles carry a date code that starts with PR01, followed by a five-digit number between 25091 and 26168. Those codes mark products made from April 1, 2025 through June 17, 2026.

According to the CPSC, the cleaners may contain Pseudomonas aeruginosa. The agency says people with weakened immune systems or external medical devices face the greatest risk of serious infection, while people with healthy immune systems are usually not affected. The CPSC reported no incidents or injuries when it announced the recall.

Why Plaintiffs Say Clorox Should Have Known

The plaintiffs allege Clorox should have been aware of the risks and taken quality control precautions. They point to the company's 2022 recall of about 37 million Pine-Sol bottles over the same bacterium, which led to a $5.65 million class settlement and a $14.15 million civil penalty. They also allege Clorox waited more than 11 weeks after production ended to announce this recall.

Their claims include violations of California consumer protection laws, fraudulent concealment, breach of implied warranty and unjust enrichment. They seek damages and court-ordered changes, including Spanish-language recall outreach.

These are allegations only. Clorox has not been found liable, and representatives did not respond to a request for comment in published reports.

The plaintiffs also criticize the refund process. Consumers must submit photos of the UPC code and date code, yet many bottles have been used up or thrown away. Under the recall terms, buyers who register receive a full refund with a receipt or the suggested retail price without one. Anyone who bought these cleaners should stop using them, keep any bottles or receipts they still have, and record any health problems after use.
