I did some cleaning out/organizing this weekend. I have a bottle of ammonia that I know I've had since college (so, over 10 years) and a half used bottle of canola oil that has expired. How should I dispose of these? Dr. go og le said I could pour the ammonia down the drain with a lot of water, but I guess I'm hesitant to do that without a second opinion. And you ladies are my second opinion.

How do you think I should dispose of these 2 containers full of liquid?
