I was using another product, and the smell would come right back. Tried these and the one thing I noticed is the tablets are much larger than any of the other ones I've used. Used it last week. The sink still smells fresh

Why not just lemon and ice?

It's the internet's favorite disposal trick, and it mostly just masks the problem. The ice knocks off a little loose debris, but a disposal grinds with blunt impellers, not blades, so there's nothing to sharpen. The lemon leaves a fresh smell for an hour while the food packed under the splash guard keeps rotting. Renuv foams through the whole chamber, lifts the grime where the smell actually lives, and rinses out citrus clean and septic safe.

Your kitchen smells, and the disposal is where it's coming from
The problem

Your kitchen smells, and the disposal is where it's coming from

Food never fully leaves the disposal. Bits of it catch under the rubber splash guard, coat the grinding chamber, and sit rotting in the gaps a rinse can't reach. You run the water, maybe drop in a lemon, and the smell is back by morning because the source is still down there.

How it works

Three steps to a fresh disposal

Run the water hot
