Thanks. Something like this:
1. Put them in front-loading washing machine, let fill up with water for a minute, pause cycle, pour whole container of bleach directly into barrel. Continue cycle.
2. After cycle finishes, wash a couple more times with detergent to lessen chemical smell. Let dry and wear.
3. Decide want them lighter, so back to step 1.
(Repeat whole process 3 times.)
The fading turned out pretty even. No bleach splotches.
