Chemical fumes

After I almost fainted from exposure to chemical fumes when using a toilet at VU library today, I started wondering whether there wasn't a different way to make toilets appear clean other than applying tons of intensively smelling detergents. Or at least a way that poses less of a health hazard. I'm sure those chloride/ammonia fumes combined with what detergent manufacturers consider "pleasant" smells can't be healthy. At least not when used in amounts like those here at VU.

And I still don't know what the people in charge of cleaning the toilets at Oulu University Library did to make their toilets smell of nothing (really nothing) when I was there a few years ago. They sould sell their knowledge to the rest of the world. It might save a few lives.
