I tried the Laundry "sheets" and found them to be a little too floral for me, a little too much of a "girly" smell.

To "agitate" my clothes during hand washing, I bring along a 2 gallon zip lock bag.

I put my clothes inside the bag, add water, detergent, and let them soak for a few minutes. Then I shake the bag for a few minutes . pour out the water, rinse the clothes and hang them up to dry.
