HOCL-based Cistern Cleaning

Solutions HOCL Cistern Bomb™ works through HOCL, a powerful oxidizer. Our cleaning formulas feature Hypochlorous Acid (HOCL) to break down contaminant residue and neutralize odors and stains at the source through powerful deep cleaning oxidation technology™. Simply follow the directions on the package, wait a few hours, and then scoop out any floating contaminant buildup. This process helps keep your tank clean. Experience the power of the HOCL Earth-Friendly Cistern Tank Cleaner and keep your cistern tank clean.

How the Cistern Bomb Cleans Your Tank

The Cistern Bomb™ uses a sodium-based ingredient that generates HOCL when it dissolves in water. HOCL is an oxidizer that breaks down contaminant residue, buildup, and odor-causing soil on cistern walls and surfaces. It goes after the real dirt in a tank, including proteins, fatty acids, amines, and sulfur compounds, then lifts it so you can drain and rinse it away.

Mechanism of Action

Oxidation at work: HOCL breaks down contaminant residue on tank surfaces through Powerful Deep Cleaning Oxidation Technology™, so buildup has less chance to take hold.

Earth-friendly: A biodegradable formula with a low environmental footprint.

Surface-friendly: Will not harm common cistern materials, including plastic, concrete, metal, and fiberglass.

Simple to store: Concentrated powder in a resealable pouch that takes up little shelf space.

Cistern Bomb™ is a cleaning product for the tank itself, not a water treatment. You fill the tank enough to cover the surfaces being cleaned, add the powder, let it work, then drain and refill with fresh water. The water used during cleaning is drained out, not kept. Follow the directions on the package

Built for Off-Grid and Rainwater Systems

The Cistern Bomb™ is a perfect fit for off-grid living, rainwater harvesting, and rural water storage. One small pouch cleans a large tank, which makes it practical for homes, cabins, farms, and emergency supply kits. Keep your storage tank ready and your water system running smoothly, without hauling heavy bottles or dealing with bleach.

Practical Use in Cistern Systems

On roofs and gutters: Dilute the Cistern Bomb™ as directed and apply it to roofs and gutters to clear debris before it washes into the tank.

In the tank: It neutralizes odors and lifts buildup from cistern walls at the source.

Ongoing upkeep: Regular use keeps surfaces cleaner and helps reduce blockages in pipes.

For any cistern: Works across tank sizes and materials. Each pack includes a free scooper for easy measuring.

Whether you’re prepping for long-term storage or cleaning up after stagnation, this cleaner simplifies the job. One pouch goes a long way, making it efficient for bulk systems. Add it to your emergency supply list to keep your storage tank ready.
