Basically, bleach vapors have gotten into my dehumidifier after I used clorox "tilex" All Purpose Cleaner With Bleach for mold control in the kitchen sink. Now the dehumidifier is blowing bleach vapor into the air, which irritates my throat and causes me sleep apnea which is extremely frustrating. Last time, this happened with the AC, and continued until I replaced the unit. How can I avoid needing to replace the unit whenever this happens? While I am sometimes successful at properly scrubbing all the bleach out of the sink after treatment, sometimes residue remains and it is activated whenever I use the sink.

    In the future, consider avoiding the "all purpose cleaners" and other brand formulations in favour of unadulterated materials such as liquid bleach, Sodium Hypochlorite (bleach), or Hydrogen Peroxide without any additives except water to adjust strength. Do not run your ac/dehumidifier during your application and removal of your odour producing anti-fungus treatment(s). Don't restart it until your environment is odour free. – Stan Dec 1 '20 at 17:34

The simple answer is: water and / or alcohol. However, if you do not know what you are doing, you risk ruining the unit - as well as creating fire, electrocution and other hazards.

My best advice: take the unit to an electrical service. They have the tools, substances, experience and knowledge to deal with the problem. It should not cost a fortune, I assume.


  1. Chlorine vapors can be dangerous to the health. Have the unit cleaned a.s.a.p. to avoid problems.

  2. Do not repeat the mistake :)


Oh my! It's generally a mistake to clean electronics with bleach. I will clean the fans with spray cleaners and simple rags/dusters, but I do my best to make sure that content stays out of the electric motor. The fan will last years just by wiping off the blades and dusting off the visible and accessible parts of the motor. I wouldn't submerge it in anything or spray any cleaners on the motor. The wire coils are coated with a material to keep electricity flowing through them rather than simply across the coils, and bleach and other cleaners will eat that coating, effectively ruining the motor.
