For general interest,
I have a ss io on order for about 9 days and finally inquired over the weekend. I had originally been told it would ship early last week.
Just got a response with a track #, it should be going out today.
Maybe, eventually, but in the drain it is diluted and will not 'just evaporate' for quite some time.
Lots say it is okay for small quantities down the drain, but I think that's from the perspective that it won't hurt your plumbing.
Some say it can impede the process that they're trying to achieve on down at the sewage treatment plant...
Others call it hazardous waste.
I guess if one is inclined to give the benefit of the doubt to the environment, it's probably good practice to not send it down the drain.
I justify doing it in the 'small' quantities that I do, which is maybe a little over a pint spread over a year's time.
For purely superstitious (ie, unscientific) reasons, when I have some to dump, I add some dish soap, lots of water, then send it down.
@Vaporific was good to point this out, I obviously found it worth knowing a little more about it than I did an hour or so ago. I'll bet there's already an FC thread all about it...somewhere...
