It takes me literally 5 minutes to rinse the little bit of remaining grain out of the bag, then I hang it in the bathroom to drip dry. I was a stubborn adherent to disposable paint strainer bags until I saw how much finer and stronger the
@wilserbrewer bag was. It made a huge difference in the amount of 'mud' I was getting in the bottom of my fermenter.
I do use a 6'x14" 400 micron hop filter I got from AIH during the boil and it is a major PITA to rinse clean after a brew. I would say that is probably the biggest chore in my cleaning routine. Lately I've been skipping the hop filter and just pitching the pellets straight into the kettle; though most of the trub ends up in the fermenter I haven't noticed a negative impact on flavor.
