Conventional cleaning products that people use to clean their air-conditioners consist of strong acid and alkali which are toxic and hazardous to human health, equipment, water table and even to the environment. Did you know the HVAC/Air-Conditioning System components consist of aluminium and plastic? Based on what we analysed, 90% of HVAC/Air-Conditioning System components are aluminium, and another 10% of the part is plastic. Besides, based on scientific research, acid and alkaline chemicals are hazardous substances, therefore when the acid or alkaline touches any part of the ceilings or walls, it will cause oxidation, alas, and the aesthetics of the building will be damaged. Most importantly, the probability of injury is high too, because acid and alkaline chemicals are not safe for people.
