Etymology
Origin of cleaner
First recorded in 1425–75, cleaner is from the late Middle English word clener. See clean, -er 1
Explanation
A cleaner is either a person whose job involves tidying and disinfecting, or it's a substance used to do that work, like soap. If the cleaner runs out of window cleaner, they might try using vinegar. Professional cleaners might work in people's homes, in which case you might call them housekeepers, or they might work in office buildings, on work sites, or really anywhere that needs to be cleaned. Some cleaners (like dry cleaners) clean clothing and other textiles. Being a cleaner is hard work — and if you've ever watched workers suspended on scaffolding using big squeegees to clean skyscraper windows, you know that it can be thrilling work, too.
