It was restricted because there was a spate of people mixing chlorine bleach

it would be safe.

Teaching them to read Hewbrew would be too expensive? Instead you
get a nation of dirty toilets. I would think that sacrificing a few
immigrants so that the rest could have clean toilets would be a
suitable exchange. I guess international safety symbols won't work
when mixing to non-toxic products. Maybe a toilet with a nuclear
mushroom cloud coming out of the bowl might work.

Well, maybe there's a chemical solution to the problem. Adding any
sulfur compount to the chlorine bleach would be easy. It would be
non-reactive until it hits the ammonia, where it's converted to
ammonium sulfide, which smells like rotten eggs.

Luckily the glass cleaner here is made with vinegar.

I have to make my own for cleaning LCD's. Vinegar, filtered water,
cheap rubbing alcohol, a little dish washing soap (for the wetting
agent), and a few drops of kerosene. There are plenty of similar do
it thyself formulas on the web.

Great, thanks to you and everyone else for the info and the links.
