Hello All! I'm new to these forums and new to being a general lab techincian for biology and chemistry departments. I have been doing some prep work for the upcoming semester and I wanted to do something about the dissecting pans used at my school. They were dirty and the wax was really marked up. I gave them all a thorough cleaning then ran them through the autoclave to melt the wax and sterilize it. I used to do this at the end of each semester for a university where I was once a work-study student and got great results.
Upon runinng the trays through a liquid cycle a few turned out nicely but most were marked and unsmooth. Any adivce would be greatly appreciated!
