Q: Do the cruise lines use harsh chemicals to clean the cabins?

A:

No, major cruise lines do not typically use "harsh" chemicals like bleach or ammonia for routine cabin cleaning. They rely on hospital-grade, EPA-approved disinfectants that are effective against pathogens but formulated to be safe for surfaces and occupants when used as directed.

On a ship, every cleaning product must be compatible with the marine sanitation system. Harsh acids or bleaches can corrode pipes and degrade vacuum toilet seals. The chemicals are engineered to eliminate norovirus and other contaminants without damaging the ship's closed-loop plumbing infrastructure.

If you have chemical sensitivities, request a cabin cleaned with hydrogen peroxide-based products. Inform your steward on day one. For added assurance, wipe down high-touch surfaces like remotes and door handles with your own alcohol wipes upon boarding.
