"Took to the cleaners" is an idiomatic expression that refers to a situation where someone has been swindled or cheated out of their money or possessions. The word "took" implies that someone has forcefully taken something from another person against their will, while "cleaners" suggest that the victim has been left with virtually nothing. Therefore, the antonyms for this phrase would be words that describe gaining, winning, or succeeding in a deal or negotiation. Some of the antonyms may include words such as "profitable", "thriving", "successful", "lucrative", or "advantageous." These words describe situations where someone has come out on top, rather than being taken advantage of.
