So what kinds of containers are you talking about, and why don't you have a "soap home", kenny
? I would be more concerned about dishwashing detergent to be left on the container than if I were washing with Dawn, or another liqiid soap by hand (and safer for my hands, too!), though the DW rinses much better than I do! When I save plastic containers, I usually put them in the DW to clean, though, and I'm sure we've all seen this, sometimes they melt from the heat!
Talenti containers do this, as well as some mushroom containers, so they always get hand washed, with soap.
