Clear Safety Steps For Every Room

description

That damp, suffocating smell is not living on your walls. Mold spores and the microbial compounds that drive persistent musty odor settle into grout, drywall paper, carpet padding, and wood grain. Those are places a scrub brush or spray bottle was never engineered to touch. That is why wiping down the surfaces gives you a week of relief and then the smell returns on cue.

CloBombs releases chlorine dioxide gas that fills the sealed room completely, penetrating every porous surface and breaking apart the compounds responsible for that deep, embedded damp odor at a chemical level.


Eliminates:
  • Basement and crawl space mustiness, including buildup from years of trapped moisture
  • Bathroom mildew that cycles back within days of every cleaning session
  • Attic and storage room odor from condensation and poor ventilation
  • Musty smell in closets, laundry rooms, and older rental units
  • General damp-home odor that candles and air fresheners only ever postpone

One kit covers spaces up to 400 square feet. Everyone must leave the treatment area for the full 1-hour cycle and 30 minutes of ventilation afterward.

Easy to Use:

  1. Place jar out of direct sunlight in a cool, shaded area.
  2. Place 2 AA batteries inside bubbler
  3. Fill the jar with water to the fill line on the left. (Approx. 5oz).
  4. Place a towel around the application area to catch any potential splashes or overflow from the bubbling solution.
  5. Turn on bubbler, and insert bubbler hose into the jar of clear water and place bubbler to the side on flat surface.
  6. Remove CloBomb from aluminum pouch and drop into jar.

  7. Exit home and allow reset to take place.

    • Allow 1 Hour of application
  8. After the 1-hour treatment, open windows and allow fresh air to circulate for at least 30 minutes before re-entering.
  9. Once complete, remove and throw away contents.

*Chlorine smell will dissipate on its own*

That damp, musty smell that comes back every time it rains? This is how you end it.

How It Works

Step 1

Place the jar on a flat, raised surface away from direct sunlight, with a towel underneath. Put 2 AA batteries in the bubbler and fill the jar with water to the fill line, about 5 ounces.

STEP 2

Insert the bubbler hose into the jar and switch it on, then unwrap a CloBombs tablet from its foil pouch and drop it straight into the water.

STEP 3

Close every door, window, vent, and fan, and leave the room immediately. Let the CloBombs run undisturbed for a full hour so the gas fills the space and works into every porous surface.

STEP 4

After the hour is up, open the windows and let the room air out for 30 minutes before anyone goes back in. A faint chlorine note right after is normal and fades on its own.

Where To Place IT?

Pick a flat, raised spot like a countertop or table at the center of the room, away from direct sunlight. Central placement works best because the gas needs open space to distribute evenly, so skip closets and cabinets and give it the middle of the room instead.

HOW MANY DO I NEED?

One kit handles a standard room up to 400 square feet. Larger basements, open-concept spaces, and rooms with heavy, long-standing musty odor do better with two kits placed at opposite ends. Multiple rooms mean treating each one separately.

"The basement smelled fine until you got to the bottom of the stairs — then it hit you."

"THE SMELL DIDN'T COME BACK THIS TIME."

We fixed a slow leak two years ago and dried everything out, but that damp closed-up smell never left. Air fresheners lasted a day. I ran one CloBombs treatment with the door shut overnight, aired it out in the morning, and the basement finally smells like nothing. Three weeks later it's still nothing.

"I couldn't find the source. I just knew the room smelled old."

"IT REACHED PLACES I COULDN'T CLEAN."

The musty smell was in the carpet pad, the closet, probably the drywall — I wasn't going to pull the room apart to find it. That's the part that sold me: the gas goes where a spray bottle can't. Ran it in the guest room, came back an hour later and the stale smell was just gone.

"Our in-laws were staying in the spare room and I was embarrassed about it."

"GUEST ROOM SMELLED FRESH BEFORE THEY WALKED IN."

That room stays shut most of the year and it always smells like a closed suitcase. I treated it the night before they arrived and opened the windows for 30 minutes in the morning. My mother-in-law asked if we'd repainted. Nothing to hide anymore.

Tap on each box to view steps

STEP 1

PREPARE THE KIT.

Place the jar in the room

Set the jar on a hard flat surface in the center of the room where the musty smell is strongest. A floor or low table works best so the gas spreads at ground level, where damp odor settles deepest.

Fill the jar with water

Pour clear water into the jar up to the designated fill line (approximately 5 oz).

Tap on each box to view steps

STEP 2

CONNECT & ACTIVATE BUBBLER.

Power the bubbler machine

Insert 2 AA batteries into the bubbler and place the machine on a stable flat surface beside the jar.

Insert hose & turn on

Insert the bubbler hose directly into the jar of water and switch the machine on. You will see bubbles start forming immediately.

STEP 3

DROP THE TABLET.

Unwrap the ClO2 tablet

Remove the chlorine dioxide tablet from its protective foil pouch. Do not handle it with wet hands.

Drop into the water

Drop the tablet directly into the jar. It will begin dissolving immediately and the gas will start releasing within seconds. Leave the room straight away.

Tap on each box to view steps

STEP 4

LEAVE THE ROOM. COME BACK IN 1 HOUR.

Exit and wait exactly 1 hour

Make sure all people and pets have left the treated space. Close all doors, windows and vents in the room and let the ClO2 gas circulate undisturbed for 60 minutes.

Ventilate and cleanup

After 1 hour, open the windows for 30 minutes to air the room out. Any faint chlorine scent clears on its own. Everyone can return once the room is fully ventilated.

Stop masking. Start destroying. Engineered to eliminate odors at the molecular level.

ACTIVE TECHNOLOGY

Chlorine Dioxide Gas

Oxidizer

Not A Spray

Not A Perfume

A ClO₂ tablet reacts with water to release gas that chemically breaks apart the musty odor compounds instead of covering them up.

MICRO-GAS VAPOR

Battery Powered

Micro-Gas

Whole-Room Reach

A small bubbler agitates the water so the gas expands out of the jar and spreads through the entire room, including closets and cabinets you leave open.

TREATMENT CYCLE

Doors Closed

Fans Off

Room Empty

With windows and doors shut and the room empty, the gas has a full hour to reach into carpet padding, drywall, insulation, and stored fabric where musty odor actually lives.

AFTER-EFFECT

ZERO RESIDUE. NOTHING LEFT BEHIND.

30-Minute Airing

Trace Vapor

No Residue

The odor molecules break down into harmless water vapor and CO₂, and any chlorine smell fades on its own. No wiping down surfaces afterward.

The chemistry that makes moisture-based odor permanent is exactly what ClO₂ is built to destroy.

Frequently asked questions

Does this really get rid of musty smell for good?

It does not cover the smell. The oxidation process breaks the organic odor compounds apart so they convert to trace water vapor and CO2. Most rooms clear after a single cycle. Spaces with years of moisture buildup can need a second pass, and any active moisture source should be addressed separately.

Is it safe to use in a basement or bathroom with no windows?

Yes, provided every person and pet is out of the space for the full hour and the 30-minute ventilation period after. Seal every door, vent, and fan before starting, and keep the area off-limits until airing is complete.

Is it safe on tile, grout, drywall, and carpet?

The gas works into porous surfaces without leaving any residue. Position the jar on a flat, raised surface at the center of the room rather than pressed against a wall or tucked into a corner.

How many kits do I need for a large basement?

A single kit handles spaces up to 400 square feet. For open-plan or larger basements, run two kits placed at opposite ends at the same time. Treat separate rooms individually.

What is that chlorine note right after the treatment?

Completely normal. It clears within a few hours once you have opened the windows. Nothing went wrong.

How long does the whole process take?

Around 90 minutes total. That covers the sealed 1-hour treatment cycle plus 30 minutes of open-window ventilation before anyone goes back in.

What's your shipping and return policy?

Orders ship within 1 to 3 business days with tracking. If a kit arrives missing parts, broken, or defective, contact us within 30 days of delivery and we will make it right.
