FAQs
If you find mold and mildew in your tubs and showers, the first step is to kill it to prevent it from lingering on the surface and spreading. To kill the mold or mildew, apply an EPA-registered antimicrobial with a mildewstatic claim, like Ecolab’s Scrub Free Bathroom Cleaner and Disinfectant (EPA Reg. No. 1677-256). Ensure the product remains on the surface for the contact time indicated on the product label.
To prevent mold and mildew, make sure to thoroughly rinse and dry surfaces when cleaning a shower or bathtub. Mold and mildew can grow in almost any warm, moist environment. Preventing standing water or excess moisture is an ideal way to prevent mold and mildew from growing or spreading.
Based on a third-party survey of 598 hotel guests conducted on behalf of Ecolab in November 2025, mold and mildew in tubs and showers is the #1 cleanliness issue preventing a 5-star rating. In fact, 60% of hotel guests would consider staying at another hotel on a return visit due to mold and mildew, and 92% of hotel guests would downgrade an otherwise 5-star stay over it.
