The Perfect Kitchen Sponge

Updated: Apr 19, 2023

Standard kitchen sponges begin to smell foul within a few days use. That awful smell comes from the 10 million bacteria per square inch found in the typical sponge, making the kitchen sponge the dirtiest thing in the typical home. And you use that filthy sponge to “clean” things in your kitchen then throw it away because you can’t stand the smell. That’s gross!

The NoStench™ Sponge is GUARANTEED not to stink for 90 days! NoStench™ technology prevents odor causing bacteria from living on / in the sponge for 90 days without using poisons! No more stench! The non-toxic protection resides throughout the entire sponge material - it doesn’t wash out and doesn’t fade. This is the PERFECT kitchen sponge!

NoStench™ Sponges are made with the highest quality materials and construction for the height of effectiveness and durability.  Simply the best kitchen sponge available. Each sponge is 5.625 inches x 3.875 inches of fantastic cleaning and NoStench wonderment!


The amazing NoStench™ Sponge is factory treated with the same revolutionary long lasting Everest™ antimicrobial that uses a physical kill of odor causing bacteria – NOT poisons. The factory treatment forms a nano-scale biostatic layer throughout the sponge materials. This protection is invisible and can’t be felt. 

It consists of millions of carbon-based nano-spikes that self-assemble in layers and bond covalently and intertwine with the sponge structure. Each nano-spike is made up of a carbon shaft with a nitrogen molecule at it’s base. The positively charged nitrogen interacts with the negatively charged odor causing bacteria/mold/mildew/fungus like a magnet that draws it down onto the carbon spike. 

The result is a physically ruptured or “stabbed” odor causing bacteria that can’t survive – or adapt to become resistant. Odor causing bacteria cannot get established within the NoStench™ Sponge. That is how it remains free of the foul odors! The nano-spikes are very durable and will remain viable and safely protect the sponge from odors for at least 90 days – no matter how many times it is used or washed.


Each NoStench™ Sponge is unconditionally guaranteed against stench for a full 90 days from the date of purchase. If at any time during the 90 day period the NoStench™ Sponge stinks, it can be returned for a full refund.

(Note: it is necessary to adequately rinse the sponge after each use. Food particles left on sponge can support bacteria growth that may cause odor, but the sponge materials themselves are protected from odor causing bacterial growth)
