That is fugly...lol Where are the connector covers that come with the connectors? If they are gone or lost, go to any farm store (Tractor Supply works) and get slip over covers, they are cheap.
Every push to connect QD fitting will lose some fluid when disconnected. Fact of operation. I never let the connections get that cruddy, always install the covers when not in use.
The big issue with open QD ports is dirt will get in and cause the poppets to not seal properly and the crud gets in your fluid too.
Cover them up...
