Prorestore ODORx 9‐D‐9. General purpose smoke odor counteractant. Specially formulated to manage smoke odors, it detoxifies and knocks down strong odors fast and efficiently.

9-D-9 is an odor control product used primarily to eliminate smoke odor. 9-D-9 is a blend of odor control counteractants, solvents and detergents that reduce the spread of odor causing molecules into the atmosphere. 9-D-9 also contains surfactants that help it penetrate into odor damaged surfaces. The surfactants help 9-D-9 disperse when it is used as an odor control additive in water based cleaning solutions. When applied to porous or absorbent materials, the solvents in ready-to-use (RTU) solutions of 9-D-9 vaporize and dry rapidly thus promoting the desorption of smoky malodors from treated surfaces.

9-D-9 is used in three different applications:

  1. Suppression spraying for immediate knockdown of odor. Suppression spraying is the first step in the Unsmoke 3-Step Odor Removal Process.
  2. As an additive to water-based cleaning solutions
  3. As an additive to Unsoot #1 in deodorizing presealers. In this application, the presealer is applied to surfaces that might otherwise be a source of secondary soot contamination such as charred framing. The addition of 9-D-9 provides enhanced odor control.


  • Direct contact with contaminated surfaces provides an initial reduction of strong, objectionable odors.
  • Detoxifies smoke- and fire-damaged job sites.
  • Inhibits the evaporation of toxic fire-related vapors.
  • Apply with a compression sprayer or an airless paint sprayer only. Do not use with a fogger.
  • May be added to other water-based cleaning solutions to increase their effectiveness.

Product Application

Dilute for use. Do not use with a fogger.

Detoxifying smoke- and fire-damaged job sites: Treating smoke-damaged surfaces and charred materials with 9-D-9 solution inhibits the evaporation of toxic fire-related gases.

For charred wood or additional odor control: Add 1 ounce of Last Resort to each gallon of 9-D-9 solution as prepared above (8 mL / L).

Use with other products: Up to 1 oz. of 9-D-9 may be added to a ready to use gallon of other water-based cleaning solutions to increase their effectiveness.

For best results, use our Three-step odor removal process. This multistep approach to odor control addresses a wide variety of odors in many different types of buildings.

Step 1: Suppression Spraying: For most odor control situations prepare a ready-to-use (RTU) solution by mixing 3 fluid ounces of 9-D-9 concentrate with enough water to make one gallon (24 milliliters per liter). For exceptionally strong odors increase the concentration to as much as 6 ounces per gallon (48 milliliters per liter). Prepare all RTU solutions before entering the worksite. Procedure: 1) Be sure that spraying equipment is clean and that it functions properly before entering the worksite. Be particularly careful about spray nozzles to be sure they are clean and that they produce an even spray pattern. 2) Use the personal protective (PPE) equipment required for each situation. 3) Identify surfaces that were damaged by fire and smoke. Scan each room and examine all vertical and horizontal surfaces. Look for evidence of fire damage such as charring, soot trails, distorted or melted surfaces. Check areas such as closets, cabinet interiors, and behind window treatments. 4) Using the pressure sprayer, apply 9-D-9 RTU solution to damaged areas; be sure that all charred material is wetted by the solution. Use a deliberate, even application. The intention is to deliver deodorizing solution to the damaged material, not to spray fine aerosol particles into the air. Odors often settle onto horizontal surfaces, make sure to treat them adequately. 5) Check the area for the immediate reduction of odor. Proceed to the next step of the 3-Step Odor Removal Process.

Step 2: Cleaning Solution Additive: During the clean up phase of a restoration project, you can add up to 1 ounce of 9-D-9 per gallon (8 ml/ l) of detergent solutions used for water cleanable surfaces. Test to be sure that 9-D-9 properly dissolves in the detergent solution. Procedure: Use cleaning products according to the label directions specified by the manufacturer of the detergent.

Step 3: Deodorizing Sealer: Deodorizing pre-sealer for smoke damaged structural surfaces. To make 5 gallons (20 liters) of deodorizing pre-sealer, combine the following in an empty 5 gallon container. Be sure that the container is clean.

  • One gallon (3.8 liters) Unsoot #1 Encapsulant
  • One quart (950 ml) 9-D-9, and mix thoroughly
  • Five ounces (150 ml) Last Resort, and mix thoroughly
  • Add enough water to fill the container and mix thoroughly

Covers 500 to 750 square feet per gallon (12 to 18 square meters per liter) when applied with commercial airless paint sprayer or electric sprayer. Note: solution is more viscous than water and cannot be properly applied with a pressure sprayer.
