Question: how to clean air conditioner louvers?
Answer: As you did with the cover, begin by soaking the louvers with detergent, rinse and air dry. If you cannot remove the louvers, wipe them as well as you are able with hot, soapy water and air dry. Next, for both removed and in-place louvers, wipe every surface with a solution of 1 C. bleach to 1 gallon of water.
