The larger size of this Fresh Wave Pets odor eliminator container is very convenient. I've had a relatively good experience using it, and odors from my cat's litter box are virtually eliminated however I've noticed that without good air flow (e.g. using a fan), that this product does not seem to be very effective. There is a slight trace odor left by it but it is not unpleasant and barely noticeable after a few days.
I have the top of the container open and also poured the gel crystals into a few bowls, placing them nearby. I am looking for other solutions at this time and depending on which one or more works well, may reorder this.Get more detail about Fresh Wave Pets 035 64 oz Gel Crystals.
