The advice you received was correct. Most treated dust mops are treated with an oil-based chemical. Certain stones can absorb this oil, causing staining. Strongly recommend only untreated dust mops.
TIP Also, tell your customers this: When purchasing a dust mop buy as wide a dust mop as possible. This will make the task of dust mopping much easier. Buy a washable mop and frequently clean it.
