This sounds bad when I say it, and I fully respect you have a local, but being as you have 1 employee on at a time I can't imagine that business is booming, especially now when most people are hiding indoors. At the same time I know skaters aren't the most cleanly people, or people that aren't high fiving and hugging a lot for that matter. Personally I say stay open as long as you can, but as a responsible business owner it makes way more sense to close for public health.
As everyone else said I'm sure you have a Facebook page or Instagram account, worst case scenario try to communicate through them to set up purchases and go that route.
Also yea, there are other options out there as far as cleaning goes. I've been a diabetic for years and kind of hoarded alcohol swabs just by being lazy. A guy I work with keeps a bottle of Lysol on the truck to mist himself with if we're working someplace dirty.
