By the way, Daniel.
This is what I do with my fixer, selenium, and whatever else I am unsure about:

I go to the Los Feliz location, near the L.A. Zoo:
4600 Colorado Blvd.
Los Angeles, CA 90039
Hours of Operation:
Saturdays and Sundays
9:00 a.m. - 3:00 p.m.
If you are in Pasadena, take 210 west to 134 west to 5 south. Exit Colorado St., which is the first exit after getting onto 5, I believe. The ramp is a very long multi-lane ramp, and you want to get/stay in the right lane. There is another exit from the Colorado ramp, called Edenhurst. Take this exit. (Do not miss this exit, or it is a bit of a pain to turn around and get back to where you need to be.) Make a left onto the street at the end of the ramp (Colorado). Continue down the street a short distance and make a right into the driveway.
It is free, quick, and easy. All it costs is time. Take anything there. Batteries, paint, rags, etc. Just make sure it is all labeled correctly so they know what to do with it.
