This is a tip I learned from one of our critique facilitators, Julie Ferguson, who led our local writing group for decades. Unfortunately (for us) she has since moved cities, but I haven’t forgotten her many gems of advice while editing.
Read aloud. Two things happen when I read my work aloud. Firstly, I hear what I’ve written more clearly than merely reading in my head. Secondly, when I stumbled on a phrase, it usually means there’s something not quite right with what I’ve written.
