### ⭐⭐⭐⭐⭐ It works
*by A***. on May 14, 2025*

So far so good with those who say it is smelly well yes it’s a cleaner and you should be diluting it with water it says on the bottle 1 part solution up to 5 parts water. It has a windex smell. My coils were not filthy or gunky but it seems to have removed the odor that I was smelling. So in short it works and smells like a cleaner
