Quoting CL & DJs Mommy:" <blockquote><b>Quoting Sabrina~SquishyButts:</b>" all of them can hold in the pee ... [snip!] ... smell was do bad I cc ouldnt look at thrm, but they appeared clean. So rinsing is the key? Before or after the wash cycle?"
yeah if they were smelly before there was anything in them, they for sure had buildup.
I rinse, wash, rinse, rinse then dry. The key is rinsing extra after the wash, because you want to make sure to get the soap bubbles out that you put in there during the wash cycle.
