At the beginning of each day and between sessions clean each of the items on the list and check off what has been done.
If officials are responsible for their own area (e.g. judges wiping down their chairs) check that this has been done before marking complete.
What to clean with:
With disinfectant wipes/mop clean hard/plastic surfaces e.g chairs, tables, iPads, Crash mats etc.
Vacuum carpeted areas at the end of each day
