Ok, my dirty little secret. Every time I host league or a tournament, after the last person leaves, I wipe down every machine with Clorox wipes. I clean the glass with Windex, and then use he disinfectant wipes on every button, Palm bar, start button, everywhere people touch. Every time I do it I think “this can’t be good for the paint”. But I still do it, and I always will.
As for the big tournaments like Pinburgh, I use hand sanitizer after every round... but I know that only helps so much. If a pandemic is brought in, I’m a goner.
