Coaxing Critters Out of Broccoli Heads

Hi all! I’m growing organic broccoli, and I’ve seen a few articles online about coaxing the crawly critters out. Some say soak in hot water with salt, others say cold water and vinegar. Does anyone have tips and pros/cons of these methods? I do want to refrigerate it for a day or two after getting critters out. They like to keep eating no matter where they are! Thanks.
