Home depot sells it, so does target, or many other stores like lowes. It has oxcalic acid in it but lists nothing else. I just checked the can. I think it safe, just give it a few good rinses and let it dry. maybe rinse it again after that.
If you get in your eyes:save your frogs and sell them on db.
. just rinse them for 15 minutes. That seems like a long time, doesn't it.
