I already forgot the instructions I got in class.  How do I wash my shirt?? 
  1. Make sure the washer is empty.  
  2. Cut the bags & ties off-- touch the shirt as little as possible-- the dye is still active!
  3. Squirt some (1-2 Tbsp) liquid dish soap (the kind you use in the kitchen sink on pots & pans) DIRECTLY into the machine.  (NOT into a dispenser!!)  Liquid dish soap (for the sink, not the dishwasher) is essential to the washout-process.  It contains a chemical that deactivates the dye.
  4. Run on WARM as a MEDIUM* load.  (If you have a top-loader that gives you the option of starting the water and adding the dish soap before you put the shirt in, that is a fabulous idea.)
  5. Squirt another dose of liquid dish soap.  Run again on warm/medium.*
  6. If you & your mom are nervous, run it one more time as a rinse.
  7. Dry normally.  Wear proudly.  Tell people you have mad chemistry skills.
*If your washer saves water by detecting the load size for you, it won't use enough water!  You can either (1) Make friends with someone whose washer isn't as environmentally friendly as yours (double soap, large load) or (2) add a load of wash rags or dark towels to convince the washer you need more water.  (Add extra soap to be safe.)  If an extra rinse is an option, that's a nice idea too.
