What it could cost you: A plumber’s visit (and maybe a new disposal)
Proceed with caution when it comes to this well-circulated DIY fix. Citric acid is a natural deodorizer, but plumbing experts say it can corrode the metal in your disposal. That tough lemon peel can also damage the grinding components and clog your pipes. Next thing you know you’re Googling reviews for plumbers.
The better way: Turn on the disposal and, while running cold water, dump in two or more trays of ice cubes. Despite the clamor, this will safely dislodge buildup on the walls and the impellers, which grind up the food. Use vinegar to deodorize.
