I used to work with professional chemists and those who used laboratory reagents. I could get all the empty brown glass ones with Bakelite tops I wanted. I accepted isopropanol, acetone, xylene, hydrochloric acid, and similar bottles, but did not bother with syrupy stuff or chlorinated hydrocarbons because I was not sure if I could clean the bottles adequately. When that source dried up, I bought some new. If you get a full carton of bottles, they are really quite cheap. Got mine from some bottle company on the Internet. If it was D-76, some kind of development system cleaner might work. You could also try BBs or something and shake them up with the bottle partly filled with water and a little detergent or something. But at some point you may find you time is worth more and just buy the bottles. I find the 500ml and 1000ml bottles the most useful I have some 4000ml bottles and some 2000 ml bottles as well. -- .~.
