Bowdlerize, maybe

CENSOR

Think of altering text to remove offensive or inappropriate parts, often done by authorities to control what people read or see.

"Bowdlerize" means to remove or alter parts of a text considered offensive or improper, which is essentially what censoring does. The clue adds "maybe" to hint that "censor" is a broader term for the same idea—editing content to make it more acceptable. So, the answer is a straightforward synonym with a slight nudge toward the more common word.
