Sink strainers help keep unwanted scraps and unseen utensils out of your drains and away from your disposal. Chances are you’ve heard the grind and rattle of a fork that’s made its way into the garbage disposal. It’s not a pleasant sound, and the fork usually gets chipped and scratched enough to be unusable. Submerge a sink strainer when you’re doing dishes, or prop one up near your pre-rinse, to keep waste water relatively clean, utensils in top shape, and drains unclogged. They’re the safety nets of the sink, and using one could save you time and money in the long run.
