What does squeaky mean?
Squeaky is an adjective most commonly used to describe a high-pitched, sharp sound, as in a squeaky hinge, squeaky voice, or squeaky brakes. It is formed from the verb “squeak,” whose name imitates the sound itself. Squeaky also has an idiomatic meaning when used in the phrase “squeaky clean,” describing something that is exceptionally clean or polished. This expression can be entirely complimentary, as when a house has been thoroughly tidied, but it can also imply that the cleanliness is so perfect or conspicuous that it seems suspicious. The word is common in everyday British and American English and is usually neutral in tone, though its extended uses are more informal and occasionally humorous. Its usefulness lies in combining a direct description of sound with a colorful figurative expression that can praise neatness while gently questioning its genuineness.
Making or characterized by a high-pitched, squeaking sound.

Immaculately clean or polished; excessively clean, neat, or well-behaved.
"The police station was squeaky clean after the inspection."
Usually informal, and often somewhat humorous; it can imply that the perfection is suspicious or artificial.
A squeaky sound can make an ordinary object memorable, while “squeaky clean” turns an adjective about cleanliness into a playful warning that something may be too perfect to be true.
