I understand that the virus is killed by certain spectrum's of UV light and there are special lightbulbs that produce these. Perhaps at your arcade you could set up these lights in front of each game at night to disinfect the coindoor, lockdown bar, flipper buttons etc. I have no idea on how this effects paint and decals as far as fading goes though. Additionally, heat kills the virus so strategically placed space heaters could be used as well.

We use UV-C lights in our air handlers in the manufacture of cannabis. Before the UV-C we have MIRV filters.

In some areas we have UV-C lights in our air ducts. This is actually a cheaper solution. I read an article that COVID was found in the duct work in Wuhan.

These were not installed for the virus but other bio hazards that impact the crop. From what I’ve heard, these lights are hard to come by right now. We also use negative air pressure.
