1. Definition: Clean out (phrasal verb) = to remove everything from inside a space, making it empty and clean; or informally, to take all of someone’s money or possessions.

“Clean out” is a phrasal verb with two distinct lives — one literal and practical, one informal and dramatic. Both involve the idea of emptying something completely, but in very different contexts.

The literal meaning is about thoroughly cleaning a space by removing its contents. You clean out your wardrobe, your garage, your fridge, your desk drawers. It’s more intensive than simply cleaning — you’re not just wiping surfaces; you’re taking everything out, deciding what to keep and what to throw away, and often reorganising. It’s the deep clean, the declutter, the “let’s finally deal with all this stuff” project.

The informal meaning is more colourful: to take all of someone’s money or resources, leaving them with nothing. A casino can clean you out. A divorce can clean someone out. A thief can clean out your house. Unexpected expenses can clean out your savings. This usage suggests being emptied completely — financially wiped out, robbed of everything, left with nothing.

There’s something dramatic and final about “clean out” in both senses. Whether it’s your cupboards or your bank account, the result is the same: empty.

Examples from the street:

• “I spent the whole weekend cleaning out the garage — I threw away three car-loads of junk” → I emptied the space completely and got rid of accumulated rubbish
• “The casino completely cleaned him out — he lost everything” → gambling took all his money; he left with nothing
• “We need to clean out the fridge before we go on holiday” → we must empty and clear the refrigerator before leaving

2. Most Common Patterns

• clean out + space → empty and organise a place (clean out the cupboard, the attic, the car)
• clean someone out → take all their money; leave them with nothing
• get cleaned out → lose all your money (passive; victim’s perspective)
• clean out + account/savings → empty a financial account completely
• need/have to clean out → expressing the task needs doing
• finally clean out → suggesting a long-overdue task
• clean-out (noun) → the act of thoroughly emptying and organising a space
