Advice from a chemist is much appreciated! Im retired (72) & primarily use
a very small guest bathroom with a quickly nasty looking toilet bowl. I
recently used spa brominating tables instead of chlorine tablets (in a Kaboom
system that bypasses the tank) for fear of inhaling chlorine gas. The bromine
tablet worked great but also has a strong odor. Is the off gassing from
bromine or chlorine tablets toxic? Many Thanks.
