Diesel Fumes and Residue

Gas Pump

Identifying the Odor

Many businesses and homes have vehicles that are powered by Diesel Fuel. Either an attached garage with the home or a shared ventilation system with the offices in a business setting. The Walls eventually acquire a residue along with a distinct odor from the fumes of the exhaust pipes on the vehicles over time. This odor is a penetrating odor that can successfully be destroyed by using a high output ozone generator for Deodorizing.

  • Was or is there soot on your walls from diesel engines running in another part of the building or attached home garage? If you decided to repaint, did you seal the walls first with a stain sealer?
  • Did the carpets get cleaned with the correct petroleum attacking cleaning agent? Or did they get replaced?
  • Are the ceilings a lowered ceiling that is porous or are they a permanent ceiling with a porous or popcorn texture?
  • Has all the woodwork been cleaned and re-varnished or sealed?
  • Has the ventilation system been cleaned?
  • Do you share the ventilation system with the same area as where the diesel engines are running?

Odor Elimination

  • If there is a gray-black haze or film over the contents and structure, a chem sponge should be used. This is a dry process of wiping down the walls. A chem sponge can be purchased from your local Fire Restoration Cleaning Company or go online and search Chem Sponge.
  • Do not use any liquid cleaning agent or any moisture before this process. Moisture will smear the walls leaving a look that may be difficult to correct and then potentially need a paint job.
  • If there are any walls or items that are not sealed or might be porous - take caution! Something not sealed such as most lamp shades, some designer decoration and even some canvas paintings, will smear the sooty residue and becomes a permanent mess, if a liquid cleaning agent is used first. Always use a dry chem sponge first.
  • Once the 1st step of removing the sooty residue with the Dry Chem Sponge is complete, then (if needed) use a mixture of liquid soot cleaner diluted into water, preferably hot water. After wiping down the walls in this last step you must evaluate and determine if the cleaning job was successful. Repeating the cleaning might be needed.
  • The next step of using an ozone generator will eliminate the odor and the chemical reaction that takes place between soot, oxygen and paint. This will give you an even paint coverage without bleed through.
  • The carpets should be deep down cleaned with a cleaning agent or additive for cleaning up petroleum which is usually solvent based. The padding should be checked to see if it needs to be replaced before cleaning the carpets.
  • After the ozonating process is finished and the structure has been aired out with fresh oxygen from out-doors, a stain sealer may be applied, followed by the paint of your choice.
  • If the odor returns after two weeks, then a commercial grade ozone generator should be rented.
  • When using a commercial ozone generator, a lot more caution must be taken. The ozone level produced can easily handle the job of deodorizing, but if used without respiratory protection, the ozone can be a health hazard. So take caution by using a respirator with no less than P-100 filters made by AEARO AU-Safety.
