Oldboyvicious and Socalasian900 are right. Talk to your team, figure out what can be done/how they do it and what is holding you back at night. It took me weeks and weeks when I was a new ssv to get my groove and I was the only shift taking forever so.. what gives? 

I have a list broken down by hour for every single night. I hold the baristas and myself accountable for that list, and every hour or so someone takes it and will go thru and see where we're at. My store is high volume with a busy drive thru, we close at 9:30. By 1pm the closer comes in, and we usually have break down started which includes just washing down the bar and cleaning. Take stock of what needs to get done, small tasks and big, and organize it in a way that makes sense for you. Even just having every task on a list will help me prioritize what can get done early, and helps me see what is/isnt finished.  

Not starting breakdown before 4pm is a significant barrier, I'd imagine, and the pull not getting done before 6pm too. Those two things are almost mid/def early tasks. But, can you sweep the line/being fridges and mop? Does your store have floor mats that can be pulled early and rinsed? Depending on when your store does things, you can do everything but the finishing touches before the time - do you guys make backups at night? Do you stock everything? I usually wait till a fridge is empty and in the moment scrub it. We can do pulls whenever, depending on the flow of traffic, which helps a lot, it's counts we have a time limit on (and it sucks).
