Do It Yourself

ClO₂ has a 50 year history of effective use in both the EU and USA in a variety of liquid, gas & surface treatment applications, in dozens of industries and hundreds of applications.

ClO₂ is an exceptionally effective and versatile yet low toxicity odor, mold & smoke eliminator and is currently used nationally by many leading Diaster & Restoration franchises.

Reset now makes using professional grade ClO₂ simple, safe & affordable.

Chlorine Dioxide is a chemical compound made up of one atom of chlorine and two atoms of oxygen.

Do not confuse ClO₂ with typical household chlorine bleach or HTH. Chlorine dioxide is actually an oxidizing agent, not a chlorinating agent.

Unlike alternative chemicals, ClO₂ reacts with organic matter through SELECTIVE OXIDATION rather than SUBSTITUTION and does not produce carcinogenic chlorinated byproducts.

ClO₂ has 2.5 times the oxidation capacity of Cl. Because ClO₂ is a strong oxidizer and works at significantly lower concentrations than alternative chemicals, it is significantly less corrosive.

No post ClO₂ application rinsing or wiping is required.

One of the most important qualities of chlorine dioxide is its high solubility in water, especially in cold water. Chlorine dioxide does not hydrolyze nor undergo a chemical breakdown reaction when it enters water.

Instead, chlorine dioxide remains intact as a dissolved gas in water.

Chlorine dioxide is approximately 10 times more soluble in water than chlorine (Cl).

Active and Stabilized chlorine dioxide are not the same substance.

Stabilized chlorine dioxide (NaClO2) products are prepared by buffering sodium chlorite (salt) with carbonate or phosphate and hydrogen peroxide. This stabilizes the chlorite, not chlorine dioxide. Stabilized chlorite is not the same as active chlorine dioxide and does not have the same oxidizing properties. It can be used as a LIQUID only and at significantly higher ppm concentrations. Active Chlorine Dioxide (ClO₂) is a water soluble gas and can be used both in LIQUID & VAPOR Treatments.

Properties Liquid applications only; does not off-gas and can not be used in VAPOR applications.
Typically must be mixed in precise A (liquid) and B (powder) measurements, with proper water pH, to achieve use concentration solutions.
Active ClO₂ is a fee radical which is simultaneously a liquid and gas state at the same time.
ClO₂ has significantly more OXIDATION capacity than stabilized. Simply add tap water to the product or device for activation.
Effectiveness Slower and not as effective as activated ClO₂. Can only be used as a liquid. Excellent liquid and vapor deodorization capabilities. No rinse, no wipe solution.
Concentrations Can be mixed in concentrations of 2,000-6,000 ppm for effective liquid surface Treatments. Can be mixed in concentrations of 100-500 ppm for effective liquid surface Treatments.
Can be used for vaporing atmosphere, porous and non-porous surfaces.
pH Slightly alkaline at ~9 pH. Non-corrosive to stainless steel and most metals. Near Neutral 6.8 pH
Non-corrosive to stainless steel and most metals.
Personal Protective Equipment No PPE required when mixing and handling product. No PPE required when mixing & handling Liquid.
PPE required when mixing & handling Vapor.
Product Life Keeps for up to 2 years once mixed. No light sensitivity. Liquids keep for 2-3 months after activation. Significant light sensitivity; must be capped.
Discoloration Less subject to discoloration than activated ClO₂ when treating fabrics. Can discolor certain color fabrics (beige, tan, light colors) at higher than 500 ppm concentrations.
Typical Usages Surfaces & Water Treatments Surfaces, Atmosphere, Tank & Line & Water Treatments
Industries and Applications Agriculture, Horticulture, Medical, Carpet Cleaning, Veterinary Disaster & Restoration, Horticulture, Medical, Marine/RV/Auto

All Reset Tablets and Paks can be activated and safely used as either a ‘GAS VAPOR’ to deeply penetrate and clean a confined space atmosphere and its porous and non-porous surfaces, or activated as a ‘LIQUID’ to be applied by sponge, mop, wet vacuum, sprayer or fogger onto virtually any surface or atmosphere to eliminate wide-spectrum pungent and resistant odor.


Step 1: Odor Source Identification, Removal & Restoration

Source issues must be addressed or mold and odor will re-appear.

HEPA filtration could be required. For best results, use both liquid and vapor protocols (Steps 2 & 3).

Step 2: Liquid Surface Application

All rooms, beddings, surfaces, furniture, uniforms, etc.

Sprayers, Foggers, Mops, Sponges and Wet Vacuums are used for different targeted application challenges.

Step 3: Vapor Application

Step 3: Vapor Application

ClO₂ deep cleans & deodorizes atmospheres and its visible and non-visible surfaces and penetrates barriers spraying and fogging can not.

Step 4: Re-open, Air Out, Retest

Re-open and air-out space if using Vapor protocol.

Pour remaining Vapor concentrate down the toilet or drain. Re-take mold tests in same locations to determine treatment effectiveness.

Reset Pure ClO₂ tablets can be combined to activate either a VAPOR or LIQUID. For example, ten (10) 20g tablets + three (3) 100g tablets = 500 grams ClO₂.

ClO₂ Vaporing

Use a Medium (M) Deodorization Level to reset to neutral any environment from wide-spectrum pungent and resistant odors.

Use a High (H) Mold and Smoke Removal Level to remove difficult mold type issues or when deep cleaning.

Reset Pure ClO₂ is the lowest cost, easiest-to-use, high quality in-place ClO₂, available in the USA.

Reset is designed to rapidly generate use concentrations of pure chlorine dioxide that match internationally established application usage products.



Aerators are highly effective at rapidly pushing the ClO₂ out of the concentrate. Aerators are not required with any Reset product. Vapor will release from Reset concentrates over a 3 to 24 hour period.

For best results, use the Reset Aerator to agitate the Reset ClO₂ concentrate when using Reset Red products. If not using an aerator, periodically agitate the concentrate manually to help release the vapor from the concentrate.
