Last weekend I had a regular load going with my synthetic workout stuff mixed in as usual. On a whim I separated just those pieces and ran them alone on a cold quick cycle with no extra spin since the machine was already set that way. When it finished I peeked into the drum and the water looked noticeably less murky than it does after my normal loads. I’m wondering if the shorter cycle itself is what kept the water clearer or if separating the synthetics made the real difference.
