Cleaning the car air conditioner refrigerator with water and soap in 15 minutes without decoration

Hello, I read a topic in the morphology and syntax forum at King Abdulaziz University in Riyadh. Please help me with this topic as I did not find a sufficient answer. I would like you to give me your opinion: is this correct or not? And is there anyone who can help me with this topic? Is it available on the forum?
