Cleaning Tables

With the chairs going up at night and teachers/students wiping tables I am finding the cleanliness of the tables is falling to the wayside. Food is left, markers won't wipe with the chemwipes, and spilled snack is also left to dry on table tops. Could we possibly put chairs up Mon, Wed, Fri and have custodial turn the attention to a good detail clean of tables Tues/Thurs? Or is there a best system for rotational cleaning of tables vs floors to ensure all germs and items are wiped from tables?
