Frequently Asked Questions

1What Is Sweet PDZ?
Sweet PDZ is a natural earth product that captures, neutralizes, and eliminates harmful levels of ammonia and odors. It is made of premium grade clinoptilolite, better known as zeolite. Zeolites are naturally occurring minerals created from the earth’s volcanic activity that took place millions of years ago. They have a unique structure that make them uniquely suited for gas adsorption and ion exchange — special mineral properties for the elimination of harmful levels of ammonia odors like those originating from pet waste.

In 1983, the Phelps Dodge Company was the original company in the marketplace to introduce a branded odor control product from its zeolite mineral deposits, and the company trademarked it as Sweet PDZ. Today, Sweet PDZ is a trusted brand leader in the field of horse stall and animal ammonia control products.

Simply put, Sweet PDZ is a proven brand created with a natural earth mineral, and it is the power behind Sweet PDZ Horse Stall Refresher, the #1 stall deodorizer for nearly four decades.
How does it work? Sweet PDZ works because of its special mineral properties of Adsorption — the process in which atoms, ions or molecules from a substance (it could be gas, liquid, or dissolved solid) adhere to a surface of the adsorbent — and its Cation Exchange Capacity — a measure of how many cations can be retained on soil particle surfaces. Because Sweet PDZ’s ingredient is a high purity, premium grade zeolite, it is highly effective at capturing and neutralizing a variety of waste odors.
2Is Sweet PDZ Safe?
While deodorizer products often use masking scents and cover-up agents to hide odors or overpower them with a perfume odor of their own, Sweet PDZ eliminates odors naturally, by putting its unique neutralizing functions to work. It is 100% safe to breathe, handle and recycle, and its disposal-friendly properties means you can easily use your waste as a beneficial soil nutrient as the Sweet PDZ granules holds and slowly releases valuable nutrients to plants, primarily in the form of ammonium nitrogen (NH4+), potassium (K+), magnesium (Mg2+), as well as various trace elements. As a result, it promotes better plant growth by improving the value of fertilizers.
3Is Sweet PDZ Organic?
Yes. Sweet PDZ is Certified Organic through OMRI (Organic Materials Review Institute). It is all-natural, non-toxic and non-hazardous, and has no perfumes, masking scents, or colors additives. We consider Sweet PDZ a full-circle green earth mineral. It is borrowed from the earth, and it can be returned to the earth where it enhances soil, gardens and compost.

4Will Sweet PDZ Work for Other Animals Beside Horses?
Absolutely. While Sweet PDZ has been primarily sold as a horse stall refresher because of its unique ability to absorb ammonia from horse urine and improve the respiratory health of the horse, it is uniquely suited to solving all manner of animal waste problems. We recommend Sweet PDZ for creatures big and small, indoor or outdoor, exotic pets and livestock, from aardvarks to zebras and all critters in between.

For example, Healthy World Pet Deodorizer and Sweet PDZ Coop Refresher are fantastic litter additives. They are also ideal for treating household pet “accidents” whether they be new boo-boos or old stubborn messes that continue to reek of ammonia. Sweet PDZ products works wonderfully in every type of small animal habitat whether it’s for rabbits, guinea pigs, ferrets and hamsters; or in caged and housed birds. And, all Sweet PDZ products are life savers for the chicken coop, especially for backyard, urban or small-space chicken farmers where a healthy, fresh-smelling environment is essential. It can be used regularly to maintain freshness in damp, musty areas where you can let it remain in place for days, weeks and even months before needing to replenish or replace with fresh Sweet PDZ. Using the deep-litter method for chickens? Apply Sweet PDZ products or Healthy World Pet Deodorizer into the litter 1-2 times per week and each time fresh bedding is added.

A true multi-use product for households, farms, and a variety of industries, wherever ammonia and many other odors create a nuisance or a mess, Sweet PDZ is the perfect natural solution.
5Do You Need to Mix Sweet PDZ with Any Other Substance?
No, there is no reason to mix Sweet PDZ. It is very effective all by itself. Sprinkle it on trouble spots, mix it in with litter, or use more in large areas to combat spills and stall waste — it is completely safe and effective to use off the shelf, whether in powder form, for quickest odor capture or in granules for easy and thorough application.
Is it Lime? Sweet PDZ is not barn lime, hydrated lime or any other kind of lime. It is a natural-occuring clinoptilolite zeolite mineral that is pH neutral and perfectly safe for people, pets and the planet. In comparison, lime products simply don’t measure up — they mask odors rather than neutralizing them and hydrated lime is extrememly hazardous to handle or breathe.
6Is Sweet PDZ Expensive to Use?
Sweet PDZ is the most economical pet and stall deodorizer available to consumers. In fact, Sweet PDZ is really less expensive than lime or other products on a benefit-to-cost basis. For example, you’ll use much less Sweet PDZ as you would lime to control odors and ammonia. And while Sweet PDZ neutralizes odors, while lime products and other deodorizers mask odors, which means you use more and often reapply while never eliminating the source of the smell.

In addition, because of its effectiveness in creating a dry, fresh, healthful environment, Sweet PDZ’s efficiency, ease of use and transport, and its invaluable advantage in eradicating respiratory issues, lowering stress, and improving performance in horses, Sweet PDZ is, dollar for dollar, one of the best animal and pet products on the market.

Beyond Sweet PDZ’s built-in value, we strive for a price point that is consumer friendly and regularly offer promotions to our customers.
7How Long Will A Bag of Sweet PDZ Last?
How long your bag of Sweet PDZ Horse Stall Refresher will last will depend on the activities and habits of your horse. By using a simple feed scoop and sprinkling the area of the stall, routinely cleaning it, and using it on high-impact areas where urine and moisture has accumulated, you can expect a 40 lb. bag of Sweet PDZ to treat a typical horse stall for approximately 3-6 weeks.

If you have small and medium-sized pets, we recommend keeping a bag of Sweet PDZ for household accidents or to freshen the pets living space. With regular use, you can expect to have a bag of Sweet PDZ last for several months or more!

8Does Sweet PDZ Absorb Moisture?
Sweet PDZ has exceptional moisture absorption capabilities. Owing to its superior mineral functions — Adsorption and Cation Exchange Capacity — Sweet PDZ captures ammonia and odor gases, changes their chemistry, holds and neutralizes them. This molecular exchange absorbs the odor-causing wetness and then they ultimately desorb/release into the air and earth upon recycling.

Because of its absorbent properties, it Sweet PDZ products also have household and industrial applications, absorbing various gases, oils, and chemical spills as well as the toxic odors from those environments. It is also superior at capturing and removing stale, musty odors in attics, basements or and crawl spaces, or in areas following a flood.
Zeolite absorbs moisture at a rate of 40%-60% Of Its Weight. Sweet PDZ is a premium grade and highly absorbent zeolite that can absorb 40% – 60% of its weight in moisture.
9Does Sweet PDZ Work with Any Type of Bedding?
Yes. Sweet PDZ performs very well with all types of bedding, and in all types of stalls, whether they have concrete, wood, rubber mats or dirt floors. It can be used with straw in horse stalls, in the coop with all types of chicken bedding products, and it is safe to use on carpets and flooring, furnishings, and fabrics. In cat litter boxes it works equally well with traditional clay (non-clumping) litter, or clumping litter.

Our Sweet PDZ Coop Refresher also serves as a safe and beneficial grit for fowl of all kinds, as it is an excellent source of calcium. Lucerne Farms Koop Clean Chicken Bedding product, made from premium hay/straw, cut short for superior absorption and easy cleaning, serves as an excellent value-added bedding containing Sweet PDZ for additional odor control and superior coop hygiene.
Keep Your Fowl Healthy (& Fresh!) While we all love our chickens, we don’t always love the smell that comes with them. Unfortunately, that bad smell is more than just unpleasant, it can be harmful to our fowl friends. Sweet PDZ captures, neutralizes and eliminates harmful ammonia and odors. It does this with its natural chemistry. This makes your coop a more enjoyable place to visit.
10Will Sweet PDZ Keep Working Even if it Gets Wet?
Moisture does not reduce the effectiveness of Sweet PDZ to capture and load up with ammonia and odors. By its nature, Sweet PDZ products themselves are always holding some level of water inside its cyrstaline structure moisture, which is necessary for its unique mineral function to capture and hold ammonium and odors. Sweet PDZ responds extremely effectively on wet spots, pet accidents, high moisture areas, spills and flooded spaces, where its superior absorption properties are put to use.
11Will Sweet PDZ Help Get Rid of Flies?
Yes! One of the lesser known benefits of Sweet PDZ is its ability to reduce the fly population by drying damp and malodorous areas that are attractants for flies. Sweet PDZ is a desiccant (drying agent), and flies do not like to land on areas treated with it or lay their eggs in it. And, because Sweet PDZ is a natural drying agent, it causes bugs to dehydrate and die, a highly desirable characteristic for those treating in areas that attract flies, such as horse stalls, areas of standing moisture, or places where bacteria develop, such as attics or crawl spaces.
12Will Sweet PDZ Harm the Environment?
All-natural, non-toxic, non-hazardous Sweet PDZ is safe to handle (even with bare hands) and to apply while pets and livestock are in the stall or habitat. And it is not only safe for the environment, it is beneficial to the environment. After its use in the stall, the waste material and bedding containing the Sweet PDZ can be recycled and applied in pastures and gardens where it serves as a slow-release nitrogen fertilizer and soil amendment. Sweet PDZ is pH neutral, so it is excellent for use in gardening and as compost where it will not upset the soil balance, but rather bring a real benefit to it.

We like to describe Sweet PDZ as a full-circle green-earth mineral. We simply borrow it from the earth and have you apply it in stalls and all kinds of pet and livestock habitats where it captures noxious, ozone-burning odors, and then you can return it to the earth as a beneficial soil conditioner in your compost and gardens.
