This Arm and Hammer Clump and Seal review compares the regular Clump and Seal formula with Platinum. Arm and Hammer currently calls the regular formula Fresh Home, while some retailer and Platinum listings refer to it as Fresh Scent. Below you’ll see what actually differs, what owners report, and which one fits your home.
Both formulas use Clump and Seal odor-sealing technology with baking soda. Platinum adds 10% more odor eliminators than the regular formula, making that the main difference between the two.

Regular Formula: Clump and Seal Regular (Fresh Home)

Clump and Seal Regular vs Platinum: What’s Different
Both are clumping clay. Arm and Hammer says moisture-activated micro-granules form a seal around waste, and odor eliminators plus its baking soda handle the smell.
The main formula difference Arm and Hammer highlights is the odor eliminators. Platinum has 10% more than the regular formula. Both formulas in this comparison are scented.

Clump and Seal Regular (Fresh Home)
Why It Stands Out
Most reviewers say it controls odor well and forms solid clumps. Reviewers also confirm it’s low in dust, including a foster caregiver who compared it across four litter boxes.
One reviewer described the scent as clean and not overly perfumed.
Possible Downsides
It has the regular level of odor eliminators. If you specifically want Arm and Hammer’s stronger odor-control formula, Platinum is the step up.
Best For
Owners who want the regular Clump and Seal formula and don’t need Platinum’s extra odor eliminators.
Clump and Seal Platinum
Why It Stands Out
Most reviewers describe the clumps as rock hard, so less crumbles back into the box when you scoop. Most also report strong odor control.
Several reviewers in two and three cat homes say it keeps up with a busy box.
Possible Downsides
The 37 lb Amazon box is heavy and can be awkward to pour.
Best For
Multi-cat homes and boxes that get heavy use.
Other Clump and Seal Formulas
Arm and Hammer also sells Clump and Seal Multi-Cat and Clump and Seal Slide, which is made so used litter slides out when you empty the box. Our Arm and Hammer Slide review covers Slide, and the best Arm and Hammer cat litter guide compares the full lineup.
