I have been living long enough in this polykatoikia (flat building) in Athens to notice that people are used very much to using this certain chemical to clean their houses, but after finished they always throw the liquid out through their balcony and it splattered down to our common backyard, the smell is so pungent and chemically stabbing to my senses = but they seem NOT to be annoyed at all by it (so only me)!!!! Alas for me, who live on the ground floor where they toss the toxic, or any washing water leftover continuously. I can't identify who did it, it just seems any random neighbor upstairs uses the same chemicals. Sometimes it's like the habit of middle-ages Europe based on the literature I read.
Any of you perhaps know what kind of chemical they use? I use a plain chlorine (Χλορίνη) to mop my floor but it's not smelling that stabbing after that. Is it Ajax? why are people seemed to be obsessed using it? How would you confront them if you were in my situation? Would you suggest something better than that?
