The word 'whitewash' is used to describe a situation where someone tries to make something seem better than it actually is by hiding or ignoring the negative aspects. For example, if a person or a company were to cover up a mistake they made by justifying their actions or making excuses, it would be a form of whitewashing. The term was originally used to describe the practice of covering walls with a mixture of lime and water to hide imperfections, but has since taken on a more metaphorical meaning.
