Looking at today's POD (10/11) for the Maytag A902 it's interesting that only Bright Colors called for a cold wash in the washing instructions. I'm not sure how "bright" my gray t-shirts are but they all call for cold-wash only. Also boxers call for cold wash and briefs call for warm wash, regardless of color. I just ignore this whole "use cold-wash only" stupidity that certain interests are calling for and just go with what the clothing tag says. Also have to put a plug in for Cheer. Used to use Tide years ago, and it seems Cheer lives up to its old All Tempa-Cheer tagline. Gets clothes cleaner for me than Tide did in all wash temperatures, and smells better too. I think the brand of detergent you are using really does matter for cold vs warm wash emps.
