Cruise line reveals how they sanitised a cruise ship after mass coronavirus outbreak

The mammoth task was known as a “level three” clean up which is the most thorough level of sanitisation.

Spokesperson for Princess Cruises, Ms Kamali said: “‘Level three’ already existed in the cruise world.”

He explained that it was “originally written in response to norovirus but includes disinfectant that disinfects against coronavirus, as well.”

The process also included removing all linen from beds and material goods, disinfecting the entire vessel including “high-touch surfaces”, disinfecting the carpet and hard surfaces and cleaning HVAC systems.

Another spokesperson for Princess Cruises Alivia Owyoung Ender said: “Soft materials (linens, towels, etc.) were discarded and have been replaced.”
