Your local county organizes household disposal HAZ collection for free
I've use that to get rid of:
Old paint
pesticide and lumber end cut treatment. ( really poisonous stuff)
Also Lye and other corrosive stuff that's busting out of its original container - put the can inside a clean plastic container.
You've got to label it with a label that's on the list otherwise they don't know how to deal with it.

Otherwise we just try to use it up.
Living in the country allows you to have a burn barrel, so any dirty solvents from cleaning I just use to light the fire.
Any sort of corrosive things like acid, I just put in the toilet, scrub the toilet and flush like normal.
Toilet cleaner is just acid.
It's a cup full a month maybe - not five gallons at a time.
You could use the haz disposal for them too.
Dead ferric chloride, or grinder dust I feed to the roses or put in the garden - they like the iron-to a point.
If it's excessive I throw it on the gravel shoulder to keep the dust down.
That all sounds pretty redneck and sloppy
however
Nothing gets flushed that won't rot.
That means no:
tampons, condoms, plastic wrappers or wax paper strips from tampons, nothing tampon related
baby wipes, apparently they are a huge problem in city systems.
no kitchen waste flushed or sink type garbage disposals - start a composted pile.
No chemicals near the well.
Pop open the septic tank lid, make sure you know how to find it year round, = map it to the building or something.
It should not form a crust.
get it sucked out and keep an eye on it so you know how long it takes until the next clean out.
We had a clean out once in 20 years, but that's because it was crusted,
The floating crust blocked the pipe from the house backing up in the house it was still running freely.
and of course
we had to dig it out in the wintertime and didn't know where to dig.
We've never used the additives, lots of bacteria there already - but if they really do help with the crust prevention it may have saved us from a backup.
we don't use low flow toilets, water is needed to move the stuff.
