CHOOSING THE RIGHT CLEANING METHOD
When deciding between chemical wash and steam cleaning for your air conditioner, several factors should be considered. If your air conditioner is heavily soiled, has mould or bacteria growth, or hasn't been cleaned for an extended period, a chemical wash might be the more suitable option. On the other hand, if you prefer an environmentally friendly and cost-effective approach or have concerns about chemical exposure, steam cleaning is an excellent choice. It can effectively clean the surface of the air conditioner, improve air quality, and provide a safer cleaning option for individuals with allergies.
