This is the year I organize the lab.
Teaching kids to work efficiently and keep their work area neat is pretty intuitive. Washing glassware, however, is not. I’ve outfitted every station with a small plastic bin that contains a sponge, a towel, and a spray bottle of table cleaner provided by the custodial staff. There’s nothing to clean glassware. So, I added a medium-sized test tube brush to the can in each cupboard, and placed a salt shaker (2/$1 at The Dollar Store) filled with Alconox in each bin:
Alconox is my glassware-cleaning detergent of choice, when a cleaner is needed. Students usually wash their own glassware at their lab benches. They will dump a handful of Alconox in one beaker when only a sprinkle is needed. The shakers are about 12 cm tall, plastic, easy to refill, and yes, they are color-coded to match the table color scheme.
Update, November 24: Working quite well.
